8709 Liquid Flow Meter
Brand: Burkert Fluid Control Systems
Type 8709 is an instrument for liquid flow measurement in process technology. The actual value supplied by the sensor is transmitted through the digital electronics and over a standard signal output or a field bus interface.
In the device two calibration curves can be stored, which the user is able to switch between. Mass Flow Communicator software can be used for parameterization and diagnosis.
