Modbus RTU Multifunctional Ultrasonic Flowmeter Clamp On Thermal Energy Meter


TF1100-EP portable ultrasonic flow meter is designed for measuring liquid. Non-invasive transducers are mounted outside surface of the pipe. It has advantage that measurement is not influenced by pipe scale or blockage. It’s simple to install and calibrate due to unnecessary pipe cutting or flow stop.
