Volumetric flow-meters series AM

The volumetric flow-meters with oval gear wheels allow to perform precise and highly repeatable measurements, even with very viscous liquids, with up to 1,000,000 cps.

The ease of use and compactness of these products, together with the possibility of installing and independent battery power supply, make them suitable to be fixed on fixed installations as well as transfer and distribution lines for fluids, both for mobile applications such as accessories for distribution valves and guns and for any other industrial application for the control of the delivered fluid.

How it work
Two oval gear wheels are located inside the measuring body and, when pushed by the flow, they rotate in opposite directions; every gear contains two magnets which, coupled with an external sensor (reed type or hall effect sensor), transmit a pulsing signal. One of the sensors can be replaced by an analogue signal directly integrated in the electronic card. The frequency of the impulses determines the instantaneous flow rate, as every cycle corresponds to a given flow volume.
