Product Overviewe

Ultrasonic flow meters adopt a non-contact measurement principle and are easy to install. They can operate without cutting off the pipeline or stopping the water supply. Simply select a suitable measurement point, input the corresponding pipeline parameters into the device, and then fix the sensor on the outer wall of the pipeline to complete the installation, greatly reducing the construction difficulty and on-site commissioning costs.

As a flow metering instrument with high precision, no pressure loss, and wide applicability, its measurement accuracy largely depends on the reasonable selection of the installation point. Correctly selecting the installation point is the key to ensuring accurate metering, and practical applications need to meet the following core conditions:

a. The medium inside the pipeline must be in a full-pipe state

b. Reserve sufficient lengths of straight pipe sections before and after the measurement point to stabilize the water flow

c. The scaling degree of the inner wall of the pipeline is within the allowable range of the instrument

d. The on-site temperature and pressure meet the operating requirements of the instrument

e. Keep away from various external interference sources, such as vibration and electromagnetic fields

This product can be widely applied to the flow monitoring of various media such as water, oil, chemical liquids, etc. It has advantages such as easy installation, simple maintenance, and stable operation, providing stable and reliable solutions for flow measurement and energy consumption management in industries such as industrial, municipal, HVAC, and water conservancy.
