UFM-300
Fixed installation; guide-rail, pipe, wall, or panel mountable Clamp-on ultrasonic flowmeter.
The UFM-300 is a fixed installation; guide-rail, pipe, wall, or panel mountable Clamp-on ultrasonic flowmeter, which can be installed and commissioned using a Smart phone App (Android only) or a laptop computer running a configuration program (Windows).
Once commissioned the UFM-300 can continue to be operated locally as above or simply switched between local and remote operation via a Modbus RTU RS485 network for control room or Cloud based monitoring applications.
When connected to a third-party Modbus enabled datalogger the UFM-300 is ideal for remote measurement in isolated areas. Its low power operating mode means it can be powered from the datalogger for extended periods.
A complete Modbus register map is available and allows the user to locally or remotely program, interrogate and take measurements from the UFM-300.
