Measuring principle
The clamp-on ultrasonic flow meter measures liquid flow inside pipelines using ultrasonic technology.
Ultrasonic sensors installed on the outside of the pipe transmit and receive ultrasonic signals through the pipe wall and the flowing liquid. The flow velocity is calculated based on the characteristics of ultrasonic signal transmission through the flowing medium.
The measurement result is converted into electrical output signals, allowing integration with industrial monitoring and control systems.
-

Supported pipe materials include:
-
Metal pipes
-
Plastic pipes
Through simple menu configuration, one flow meter can be used to measure both metal and plastic pipelines
-
Suitable Media
The flowmeter is suitable for measuring single-phase clean liquids.
Typical applications include:
-
Tap water
-
Purified water
-
Ultra-pure water
With the expansion of application industries, the meter is also used to measure:

-
Conditions for Measurable Liquids
To ensure reliable measurement, the liquid should meet the following conditions:
-
The flowing liquid should not generate bubbles or cavitation during operation
-
Pipeline pressure should be maintained around 0.3 MPa
-
Flow velocity should remain relatively stable within the pipe
Many additional liquids have been successfully measured in real applications. For specific media compatibility, consultation is recommended.
