Description
Bamo Metallic DUM Flow Controller the flow of a liquid, free of suspended particles, having a viscosity substantially equal to water. The DUM controls the flow of a liquid, free of suspended particles, having a viscosity substantially equal to water.
Operation:
The fluid drives a magnetic orifice plate inside the cylindrical measuring tube. A spring balances its movement and allows to operate in all positions. A Reed contact, N.O. with no flow, changes of status with the passage of the magnetic orifice plate.
With these equipments, the DUM operates independently of the pressure, even with low flow-rates.
Bamo Metallic DUM Flow Controller Features:
- Operates in all positions
- Blind controller, 1 contact
- Independent of pressure
- Pressure up to 300 bar
- Flow ranges from 0.2 up to 250 l/min
Application:
Control of flow-rate in cooling systems, high pressure washing circuit, pump safety, etc.
