Clamp-on Ultrasonic Flow Meter

TUF331 (Clamp-on Ultrasonic Flow Meter)

The TUF331 is a transit time ultrasonic clamp-on flow meter that measures flow rate and total flow. It offers a 4–20 mA flow proportional output or an optional Modbus RS485 interface. It is designed to work with clamp-on transducers to provide accurate measurement of liquid flowing within a closed pipe without requiring any mechanical parts to be inserted through the pipe wall or to protrude into the flow system. It takes just a few minutes to install, and there is no need to shut down flow or drain the system.

Simple to install: clip the flowmeter on the pipe section, tighten the screw, and turn on the power—no specialist skills or tools required.

Non-intrusive clamp-on type without cutting pipe or shutting down processes.

Suitable for small pipe sizes: designed for small pipe sizes from DN20 to DN80 for pipe materials: PVC, carbon steel, and stainless steel.
