Use these doppler flowmeters measure the flow of liquids in pipes from 1/4" and larger. Each flowmeter requires a transducer (32615-66 or -68) and a monitor (32615-60, -62, or -64).|The transducers send flow data via RG59 coax cable to the monitor, and the monitor¿s software automatically adjusts filtering parameters and gain settings to ensure reliable readings are ensured over a wide range of liquid and reflector conditions. Easily configure the monitor using the front panel keypad. A two-line backlit LCD displays rate and accumulated flow values in user selected measuring units. Models 32615-62 and -64 have a 4 to 20 mA input and output for datalogging or recording. A 4 to 20 mA input must be supplied for a 4 to 20 mA output. The monitor is housed in a NEMA 4X (IP-66) enclosure. The NEMA 6 (IP67) rating has the ability to work with temperatures up to 400¿F (200¿C).
