Oval Wheel Flow Meter for Viscous Liquids

Application

Electronics

The model OVZ oval wheel flow meters are used to measure, monitor and meter viscous liquids. The flow meters function independent of viscosity in the viscosity range between 10 and 800 mm2/s. A maximum pressure loss of 1 bar has been defined at the factory.
This results in different measuring ranges for different viscosities. The oval gearwheels are manufactured from highquality plastic.
