Control and indication of flow-rate in pipings (cooling, lubricating, etc.) or in any compatible skids.

BMV series: to control and indicate the flow-rate in a vertical pipe with ascendiong flow; The liquid must be free of particles.

The solid-state body accepts high operating pressures. The liquid drives a magnetic diver inside a perforated tube (conical slots) which actuates an external analogue display on the side of device.

The magnetic coupling insures that indication can not be lost whatever the speed of rise of the diver.
At the same time, the magnetic diver actuates a N.O. contact (open without flow).
