High Performance DN25mm RS485 Modbus Digital Ultrasonic Flow Meter for Liquid Control
KUF2000 series ultrasonic water flow meter usually is used in long-term measurement at field. It has three types of sensor to measure the pipe flow: clamp on type, insertion type and inline pipe type. And it can measure heat if add temperature sensor. SD card is optional to save large quantity of data.
Inline pipe type: DN15-32mm pipes uses π shape inline pipe sensor, DN40 and above uses standard inline pipe sensor. The inline sensors has the advantages of low starting flow rate, high measurement accuracy and no pressure loss.
Clamp on type: The sensors clamp on to the outside of pipes and do not come in contact with the internal liquid. And all the models can become energy meters when connecting to temperature sensors. KUF2000 Series Clamp On Ultrasonic Flowmeter is easy for installation, no need to cut off the pipe and water, no press loss. It support measuring online long-term. Wide range of liquid flow can be measured with the sensor clamped on the pipe.
Insertion type: Only two installation holes are needed on the pipe, user can install the insertion type sensors. By using the hole making tool, the no stop flow installation can be realized. Sensors contact to the fluid directly, the measurement is stable and reliable.
