                       TDS-100P Portable Clamp-on Ultrasonic Flowmeter

                                                   - Advanced Clamp-on Transit-time flow measurement


The TDS-100P clamp-on ultrasonic flow meter is portable flowmeters which utilize the latest ultrasonic transducers technology and digital signal processing techniques. This design can provide abundant capabilities for high accurate liquid flow measurement. 

The portable water flow meters have a built-in printer which can print data as request at spot.

20 hours can ensure long time for operating without external power supply.



*Clamp-on measurement,easy installing,no pipe disturbance,no pressure drop
