Low Cost Ultrasonic Flow meter

The low cost ultrasonic flow meter is clamp-on flow meter designed for low cost and large quantity. It should be the lowest cost transit-time clamp on ultrasonic flow meter in the world.

More details


Low Cost Clamp on Ultrasonic Flow Meter



The clamp-on ultrasonic flowmeter is low cost digital liquid flowmeter which is the third generation flow product of Abest Technology. The clamp-on flow meter is also ultrasonic heat meters for thermal energy measurement. It employs advanced ultrasonic transit-time technology,and developed with surface mounting electronics and digital signal processing techniques. It can support clamp-on ultrasonic flow transduces which can provides abundant capabilities for accurate liquid flow measurement from outside of a pipe.It is also easy and simple to install clamp-on transducer installation and no special skills or tools are required

This flowmeter has four local keys which can be used for setting all parameters,including inputing value and won't need any external keypad or software.

Clamp-on ultrasonic flowmeters or heat meters have been widely used in many main lines and become more and more popular,but their high price has hindered the widespread.And this type ultrasonic flow meter is designed for large quantity application with very low cost . Its unique features, particularly very low cost, very high performance and very small size, make it the ideal choice for industrial automation, processing control, water source management, flow meter networking and OEM applications.

The flowmeters is mounted with guide rail and put inside protecting house and use special cables to connect clamp-on transducers mounted on the surface of pipes.



The low cost ultrasonic flowmeters are designed for large quantity application with low price. With rich network interface technique, the flow meter is an ideal choice for water source management,processing monitoring, industrial automation, water flow meter networking and OEM applications. The flow meter provides reliable measurement in both clean and opaque liquid flow.


Technical Spefication:
