8708 Liquid Flow Meter
Brand: Burkert Fluid Control SystemsType 8708 is an instrument for liquid flow control 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. The device offers a particularly compact solution.
MassFlowCommunicator software can be used for parameterisation and diagnosis.
