Liquid Flow Meter (LFM)

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 fi eld bus interface. In the device two calibration curves can be stored, which the user is able to switch between.
