Transit time ultrasonic flow meters measure the difference in time from when an ultrasonic signal is transmitted from the first transducer until it crosses the pipe and is received by the second transducer. A comparison is made of upstream and downstream measurements.

KUFF2000 series ultrasonic 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 adding temperature sensor.

Clamp on type: The sensors clamp on to the outside of pipes and do not come in contact with the internal liquid. No need to make any holes on the pipe. And all the models can become energy meters when connecting to temperature sensors.

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.

Inline pipe type: DN15-32 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.

• 1% accuracy.
• Wide range for various application fields. (DN15-DN6000)
• No mechanical drive in ultasonic flowmeter, parts are rarely damaged. Maintenance free and long operating life.
• Easy and quick installation. Save time with no pipe cutting or process shutdown.
• No obstruction measurement, no pressure loss.
• Connect Pt100 temperature transducer, can finish the heat/energy measurement.

Sensor selection depend on the application field parameters such as the diameter of the pipe the fix method the kind of the flow, please refer to the fix method choice chapter for details.
