All About Float Level Switches

Simple and effective

All About Float Level Switches!

Simple and effective

What are Float Level Switches

Float Level Switches are handy little devices used to detect and control liquid levels for a variety of different applications. They are relatively simple and effective. They can be used to stop liquid in a tank or vessel from overflowing, or prevent it from emptying.

What are the different types of float level switches?

Float switches can come in an array of configurations, however they are typically catagorised into vertical and horizontal. Here we will be talking in detail about two basic examples of each.

Vertical Float Level Switches

Here we can see the switch is installed in the top of the tank, as the water level increases, the float rises and activates the switch. It can also be installed in the bottom to help detect when the tank level is too low. Below we will discuss how the switch is activated.

Horizontal Float Level Switches

Here we can see the switch is installed in the side of the tank, following the same principal as the vertical ones, as the float rises it activates the switch. These particular ones are sometimes referred to as finger level switches due to the float looking a bit like a finger moving up and down.

How does a float level switch work?

Float level switches commonly use reed switches and magnets to activate or deactivate the switch, aka open or close the circuit.

What is a reed switch?

Reed switches are fairly simple contraptions. They are usually very small glass capsules, inside containing two magnetised reeds from either side. When a magnet comes in proximity, the magnetic attraction forces the closure of the reeds. This allows a current to flow through the leads at either end of the reeds.

So how are they configured in a float level switch?

In a vertical float level switch, the reed switch is in the non-magnetic stem, while the magnet is in the float.

As you can see in the below demonstration, as the liquid level rises, the float rises with it, moving the magnet into position, causing the reed switch to close, allowing a current to flow through.

There are plenty of uses for vertical float level switches.

For example, in this instance the signal may be telling another device to stop filling up a tank, or alert an operator that the tank is full and needs emptying.

A vertical level switch can also be placed at the base of the tank, instead telling another device that it needs to start filling the tank again, or alert an operator that the tank is emptying.

Here we can see a horizontal level switch. It follows the same basic principals, just configured differently.

As you can see they are simple devices that are very effective for monitoring liquid levels.

All About Temperature Switches!

All About Mechanical Temperature Switches!

Low cost, compact, and accurate

All About Mechanical Temperature Switches!

Low cost, compact, and accurate

What are Temperature Switches?

A temperature switch is a mechanical or electrical device that reacts when a certain set temperature is reached. It is utilised in manufacturing and industrial processes by turning on or off when the temperature rises or falls to the set degree. Examples of their uses include turning off a machine before it overheats, or to turn on the cooling cycle in your fridge to get it to the right temperature.

What are the different types of temperature switches?

There are a number of different types of temperature switches that use different operating principals. They categorised into either mechanical or electrical. Here we will be talking about mechanical temperature switches.

Mechanical temperature switches operate without a power source, making them a cost effective and reliable solution. There are two main types of mechanical temperature switches.

Bimetallic Temperature Switches

Bimetallic switches utilise the bimetallic strip, which converts a change of temperature into a mechanical displacement. A bimetallic strip is a strip consisting of two different types of metal, often steel and copper (sometimes brass) fused together.

They are then fixed in position at one end with the other end free to move.

As temperature increases, the metal with a larger thermal coefficient will try to expand and get longer. However, as it is fused with another piece of metal, the only way it can do that is by bending.

This physical movement is then used to connect or disconnect a circuit.

This demonstration features a normally closed switch, as the circuit remains closed at rest, they are also made as normally open.

Fluid Expansion Temperature Switches

Fluid expansion temperature switches come in a variety of constructions, however they all rely on a chamber or bulb that is filled with a gas or liquid. Upon heating, the liquid inside expands, causing the physical movement of a part such as a bellow, that opens or closes a circuit.

Our range of PDTF temperature switches use the fluid expansion principal, utilising an internal bellow that pushes the switch contacts when the liquid expands.  Let’s look at how them in detail.

Parts of our fluid expansion temperature switches:

  • A fluid filled chamber within the temperature probe
  • A bellow that extends as the liquid expands inside
  • An adjustment screw to adjust the distance between switching contacts, in order to change the set point
  • A spring to provide resistance against the bellow
  • Switch contacts that allow current from an external power source to pass through them when they touch.
  • Terminals to connect the external power source to the contacts.
  • Process connection, a threaded port to the switch to the process unit

In the demonstration below we have a normally open temperature switch, the process connection would be screwed into the system with the probe within the media.

  1. Here the system is at resting temperature, therefore the liquid is settled, and the electrical contacts are not touching.
  2. As we increase temperature in the system, it causes the liquid to expand, and the bellow starts extending
  3. Once the bellow extends enough to reach the set point, the electrical contacts touch, and a circuit is created.

This demonstration features a normally open switch, as the circuit remains open at rest, they are also made as normally closed.
However, for ease of functionality across multiple applications, they are commonly manufactured to have both NO and NC components, we call this “changeover“.

Titan Turbine Flow Meters

Titan Turbine Flow Meters

Turbine Flow Meters – for Flow Measurement Control

Titan’s own turbine flowmeter range is all based on the Pelton wheel technique. This well proven method is the ideal way of measuring low rates of flow of low viscosity liquids.

Their comprehensive ranges of radial flow turbine meters offer a selection of products for many differing types of application.

Some are suitable for chemical plant others, for the semi-conductor industry and others are ideal for drink dispense or beer monitoring equipment.

All have rugged bearings and excellent repeatability. The choice of fitting type reflects the function of the meter, some have simple hose barbs and others may be fitted with custom designed process connections to suit an OEM installation.

The Technology

Titan’s small turbine flowmeter range use a radial flow principle based on the Pelton wheel technique. This well proven method is the ideal way of measuring low rates of flow of low viscosity liquids.

For these mini flowmeters, a jet of fluid is directed at a turbine that is mounted on robust low friction sapphire bearings. The geometry of the turbine and the fluid chamber ensures that the rotational speed of the rotor is proportional to the flow rate through the device. The use of this radial arrangement allows more energy to be imparted into the turbine, so the bearing drag is far less important. Furthermore, because more energy is available the bearings themselves can be a lot stronger so increasing the life of the flowmeter. For larger flows, some of the liquid can bypass the turbine chamber, which then behaves as a “shunt” to the metered fluid. Accuracy is still maintained and the output remains linear.

AW-Lake Turbine Flow Meters

Turbine Flow Meters – for Flow Measurement Control

Axial turbine flow meters are designed with wear resistant internal components to provide trouble-free operation and a long service life.

Fluid entering the flow meter is first conditioned by the inlet flow straightener which reduces turbulence in the fluid. The moving fluid causes the rotor to spin at a speed that is proportional to its flow rate.

As the turbine blades on the rotor pass through the magnetic field of the pickup, an electronic pulse is generated. This pulse train signal can then be used to monitor the fluid’s actual flow rate or the total amount of fluid that has passed through the flow meter.

The number of electronic pulses generated by the meter, per unit volume, is known as its K-Factor. Each flow meter is calibrated to find its unique K-Factor, which is supplied with the flow meter when purchased.

What is Pressure?

Lil Engineers!

What is Pressure?

An educational resource to help understand the basic concepts of pressure

Pressure can be explained as the amount of force on a certain area.

Believe it or not, the air surrounding you has pressure, it is called atmospheric pressure. It usually reads a bit over 1 bar, but if you look at your weather app it might tell you something around 1015hPA (this is just a different unit of measurement, there are 1015 hPA in 1.015 bar… For this exercise we will keep things simple and refer to everything in the bar unit).

Interestingly, the atmospheric pressure is different depending on where you live, and is also affected by the weather.

Pressure can be found everywhere!

The weight of your body standing on the ground has pressure, the liquid you pour through a funnel has pressure.

Although it may seem like an invisible force, sometimes we can see it in action. If we look around the house, maybe we can find some examples of things that are “pressurised” around your house, these are things where the pressure is higher than the outside pressure.

Can you think of anything around the house that is pressurised?

Here’s one to get you started

Turn on a tap!  See how the water gushes out… this is because it is pressurised in the hoses that lead to it. Often the water we get in our taps is stored in a reservoir in the highest point nearby, maybe a hill or a water tower. Then it travels through pipes to your house which is lower than the water reservoir, which creates pressure allowing it to push out of your taps. In Australia, the ideal standard for water pressure is 5 bar. This is an example of water pressure.

Are there any other things that you can think of that have water pressure?

What about water guns! Without going into detail about the mechanics of a water gun, we can at least understand that in order for water to squirt out and hit your friend or sibling, it has to be pressurised!

These are easy to see because water is visible, but what about air? We know that the air around us has pressure (around 1 bar) so…

Can you think of any examples where you might find air that has more pressure?

The tyres in a bike or car do! Have you ever had to “pump up your tyres”? An air pump compresses air and pushes it into your tyres to inflate them, this makes your tyres bouncy and reduces the feeling of bumps and lumps while you’re moving.

Bike tyre pressures vary depending on the type of tyres, the ideal pressure can range anywhere from 1.7 bar to 8 bar!

Car tyre pressure doesn’t vary as much, and they usually are around 2.2-2.6 bar.

Are there any other things that you can think of that have air pressure?

We just spoke about inflating tyres… what else can be inflated?

Balloons! When we blow air into a balloon, we are creating air pressure that inflates the balloon. And the same goes for blowing up inflatable pool toys!

What do we use pressure for?

Now we can see that pressure is all around us in our homes, we can think about how it is used in an industrial setting.

Pressure is INCREDIBLY useful in manufacturing for example. We can use it to make objects move, we can use it to detect faults, we can use it to clean, it is utilised in almost every aspect.

What is an example of pressure being used in industry?

Here is one way we can use pressure in industry. Let’s have a look at the image below.

The device on the left is called a cylinder, inside is a piston rod that can move left to right. Here it is not pressurised, and the rod is in it’s resting position to the left.

What would happen if we added pressure to the left hand side of the rod by pushing air in?

We can see that pushing pressurised air into the left side of the cylinder, the piston rod moves to the right and extends it’s foot, which pushes the box!

This is a simple demonstration of how pressure can be utilised.

All About Mechanical Pressure Switches!

The low-cost and reliable pressure sensor

What are Pressure Switches?

Pressure switches are used to operate an electrical contact when a certain pressure in a liquid or gaseous medium is reached. They can be used to switch another device on or off from rising or falling pressure.

They are sometimes referred to as electro-mechanical pressure switches or pressure sensors.

It is important to not confuse them with pressure transducers or pressure transmitters, which convert pressure into an electrical output signal.

There are two types of pressure switches, mechanical and electrical. Today we will be talking about mechanical pressure switches.

How do mechanical pressure switches work?

Firstly, let’s look at what makes up a pressure switch.

Parts of a mechanical pressure switch

  • A pressure sensing element, usually a diaphragm or piston that acts as the pressure detection element.
  • An adjustment screw to vary the set point.
  • A spring to provide resistance against the pressure sensing element
  • Switch contacts that allow current from an external power source to pass through them when they touch.
  • Terminals to connect the external power source to the contacts.
  • Process connection, a threaded port to the switch to the process unit

In the demonstration below, we can see that the pressure switch is connected to the system at the process connection.

  1. Here the system is not pressurised, therefore the diaphragm is in a resting position, and the electrical contacts are not touching.
  2. As we increase pressure in the system, it causes the diaphragm to collapse and compress the spring.
  3. Once the spring compresses enough to reach the set point, the electrical contacts touch, and a circuit is created.

This demonstration features a normally open switch, as the circuit remains open at rest, they are also made as normally closed.
However, for ease of functionality across multiple applications, they are commonly manufactured to have both NO and NC components, we call this “changeover“.

How to choose a pressure switch

Pressure switches come with a vast array of options. In order to select the correct pressure switch for your system, it is important to gather as much information as you can.

Below are the vital pieces of information we need to select the perfect switch for your application:

  • Pressure range or switching point – the pressure you require it to switch at, and whether it is rising or falling
  • Port size – usually ⅛” or ¼ and BSP or NPT
  • Switch type – Normally open, normally closed, or changeover
  • Electrical connection – usually a DIN plug, flying leads, or spade terminals
  • Body material – usually brass, steel, stainless steel, or plastic
  • Pressure sensing component – we typically stock diaphragm type switches. These come in a few material options including Nitrile (NBR) as a standard, or Viton, and EPDM options.
  • Maximum system pressure – also referred to as overpressure

In addition to this, it may help us to know the following:

  • Fluid media – what is going through the switch
  • Minimum/maximum temperature – of the switches environment
