Clamp-on Liquid Flow Meter, also known as clamp-on liquid flow meter, is a non-contact flow measurement instrument that measures the flow of fluid in the pipeline through a sensor installed externally on the pipeline without direct contact with the fluid. This flow meter has the advantages of easy installation, no interference with fluid flow, and is suitable for pipelines of various materials, so it is widely used in many industrial fields.

 

Working principle

 

Clamp-on Liquid Flow Meter mainly measures flow based on the principle of ultrasonic time difference method. Specifically, it uses the fact that when ultrasonic waves propagate in the fluid, the flow of the fluid will change the propagation speed of the ultrasonic waves, thereby generating a time difference (i.e., the time difference between downstream propagation and upstream propagation). By measuring this time difference and combining parameters such as the inner diameter of the pipeline and the sound velocity of the fluid, the flow rate of the fluid can be calculated.

 

Main features

 

Non-contact measurement: The sensor is installed outside the pipeline and does not directly contact the fluid, avoiding the risk of damage to the sensor due to fluid properties (such as corrosiveness, high temperature and high pressure, etc.).

 

Easy installation: No need to drill holes or weld on the pipe, just fix the sensor to the outside of the pipe with a clamp, which greatly reduces installation time and cost.

 

Wide range of applications: It can be used to measure various liquids, including corrosive liquids, high viscosity liquids, and liquids containing solid particles.

 

High precision: Through advanced digital signal processing technology, high-precision flow measurement can be achieved to meet the needs of various industrial applications.

 

Remote monitoring: Some Clamp-on Liquid Flow Meters support communication protocols such as RS485 and Modbus, and can be connected to computers or control systems to achieve remote monitoring and data transmission.
