VOLUMETRIC MEASURERS
VOLUMETRIC MEASURERS
I volumetric flow meters They are precision instruments designed for the direct measurement of the volume of liquids that pass through a pipe. Unlike other technologies, volumetric technology (positive displacement) allows for mechanically and constantly detect the actual quantity of fluid transited, ensuring accuracy, repeatability and reliability even with high viscosity fluids or in the presence of pressure variations.
Comhas proposes a complete range of industrial volumetric meters, selected among the best international producers such as Badger Meter, Flomec, GPI e Kytola, brands recognized for the quality of their construction and the precision of their solutions. Thanks to over forty years of experience in measurement instrumentation, Comhas It is able to offer robust, calibrated and customizable instruments, accompanied by technical consultancy and specialized after-sales support.

How volumetric meters work
Volumetric meters are based on the measurement of a svolume posting Each rotation, displacement, or defined volume of fluid corresponds to a known amount of passage. Among the main available technologies:
- Gear or lobe meters : they measure the flow rate through the synchronized movement of two gears, guaranteeing high precision even with oils, fuels or viscous fluids.
- Oscillating piston meters : ideal for low flow rates or clean fluids, they ensure linear and constant measurements over time.
- Nutating disc meters: compact and economical solutions, perfect for standard control and dosing applications.
