Description
Ultra Low Flow SensorsThe Type ULF Ultra Low Flow Sensors are available in two flow ranges. They contain a transducer and a four blade paddle wheel rotor with a permanent magnet inside each blade. A square wave output signal is generated with frequency proportional to rate of rotor rotation and flow velocity. This pulse output is normally fed to a FlowX3 flow monitor/transmitter, blind transmitter, batch controller or adjustable flow switch. It can also be fed to other brand instruments or PLC’s. Two types of sensors are available, Hall Effect which requires a 5 to 24 VDC power supply and Reed Effect which have a volt-free contact. Reed Effect is required with the battery powered flow monitor. Hall Effect signals may be transmitted up to 300 meters (984 ft.) without the need for conditioning whereas Reed Effect signals may be transmitted up to 16 m (52.5 ft.) without conditioning.
