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
