Oval gear flow meters type VO with flange connection are available with process connection in sizes DN 15, DN 25 or DN 50. The housing is made from stainless steel or aluminium. They were developed for volume and flow measurement of liquids, and are used in applications including:

• Lubricant monitoring
• Food, beverages and tobacco production

Description:

• Positive displacement meter for volumetric flow rate or total flow measurement
• No inlet or outlet section required
• High-quality construction for long service life and high reliability
• Long-term stability
• High measurement accuracy and repeatability
• Easy installation

Function
Oval gear meters are displacement-type volume meters that transport defined incremental volumes in individual measuring chambers. The measuring element consists of two high precision toothed oval gears, which are driven by the flow of the medium and mesh with each other. In this way, a defined volume is transported for each rotation of the pair of oval gears. The number of rotations is a measure of the amount of fluid that has passed through the meter. The rotations are detected by a sensor
