Descriptions bamo Flow rate indicator and controller BMV SERIES

The BMV flow rate indicator is a variable area flow rate indicator. The instrument must be mounted on a vertical pipe with ascending flow. The acceptable fluid viscosity is close to water viscosity. These instruments may be available for airflow rate indication and control: on request.
The built in magnet of the diver drives the indicator. Coupling of both devices allow a continuous indication even with quick changes in the flow rate. The Reed contact, by side, is continuously adjustable. The switch is bi-stable and NO (normally open with flow less). It acts when the diver passes in front of it.
