Bamo DUM/A Metallic Flow Controller with Indicator

Description

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

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 equipment, 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.

Features:

  • Operates in all positions
  • Indicator, plus 1 adjustable contact
  • Versions: Stainless steel or brass
  • Pressure: up to 300 bar
  • Flow ranges: 0.2 … 250 l/min

Application:

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

SWITCH FEATURES

Adjustment: The housing slides along the body for threshold adjustment; 2 screws fix the setting safely.
