The DUM/A is designed for cooling piping monitoring, high pressure washing systems, dry run pump protection, etc.

The DUM/A controls and visualizes the flow in a pipe of a liquid free of suspended particles.

Operation:
The liquid drives a magnetic orifice plate inside the cylindrical measuring tube. A spring balances its movement and allows to operate in all positions. An adjustable Reed contact changes of status with the passage of the magnetic orifice plate; which drives the pointer on indicator.

With these equipments, DKM/A operates independently of the pressure, even with low flow-rates.

The magnetic coupling insures that indication can not be lost whatever the speed of rise of the diver.
