Product Description

The MilliFlow M32 is a piston-type flowmeter based on the positive displacement principle, consisting of four radial pistons driven sequentially by the fluid’s head pressure. The pistons are connected to a crankshaft, which is linked to a counter/pulse transmitter via a magnetic coupling.
