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

The BV series controls the flow-rate in a vertical pipe with ascending flow; Liquid must be free of particles.

The fluid passing through the controller, from bottom to top, drives a diver with built-in magnet which actuates an external Reed contact, adjustable all along the body. The cylindrical diver moves inside a tube perforated with conical slots.

The upper edge of the float indicate the flow rate.
- The scale is graduated in l/min of water.
- The setting of trigger point is possible over the entire measuring range.
- The actual flow-rate can be greater than the high range without damaging the device (it results in a higher pressure drop).

These controllers must be installed far from any magnetic induction.
