8039 Paddle Wheel Flowmeter with Optical Principle

Brand: Burkert Fluid Control Systems

This flowmeter with an extra-large display is specially designed to switch a valve and to establish a monitoring system or an On/Off control loop. Switching points can be programmed with the 3-key keypad under the display and the connection to the process in the piping is done with standard fittings. The version with a frequency output makes it possible to transmit the paddle wheel rotation speed (2 pulses/paddle wheel rotation) directly to a PLC.
Features
  • Indication, monitoring, transmitting and On/Off control in one device
  • Configurable outputs (Transistor or relay)
  • Optical measurement principle:
    • Insensitive to magnetic fields
    • Flow sense detection
    • Insensitive to ferromagnetic particles in the fluid
