The TUF331 is an ultrasonic clamp-on flow meter that measures flow rate and total flow with a 4-20 mA flow proportional output or optional Modbus RS485 interface. It has an integrated structure and can be used as a stand-alone meter or part of a management system.

Installation is easy: clip it on the pipe section, tighten the screw, and turn on the power. It’s non-intrusive and suitable for small pipe sizes, from materials DN20 to DN80, with no need to cut the pipe or shut down processes.
