Oval gear meters are volumetric meters and are most suited for liquids with a viscosity up to 1.000 mPas. (special models up to 500.000 mPas.). Due to the robust nature of this particular flow measurement technology, the meters can be used where other types of measurement technologies are not suited.. The meters handle very viscous or highly corrosive fluids. They have been designed for a variety of chemical applications including petroleum-based fluids, water solutions and any other liquid compatible with the materials of construction.


Flexibility of installation options (vertical installation or horizontal installation)

• Minimum number of wearable parts for long product life and easy field servicing

 Wide range of instrumentation available for control system interfacing


 Compact size

 High accuracy and repeatability

 Factory calibrated (stated in pulses per liter)

 Low pressure drop

As fluid passes through the metering chamber by entering
the inlet port, it forces the internal gears to rotate and exits
through the outlet port. Each rotation of the gear displaces
a given volume of fluid. Controlled clearances between the
gears and chamber wall ensure minimum leakage. As the
gears rotate, a magnet on each end of the gear activates the
reedswitch and forward the pulses to the display or to the
pulse output.
