In order to improve the measurement accuracy of the water meter and reduce the loss of water measurement, the C-level water meter with wide range and high precision will gradually replace the A-level and B-level water meters, which is an inevitable trend in the development and application of water meter technology.

Ultrasonic flow meters are the use of ultrasonic waves to measure the velocity of fluids and are used in various fluid applications. Ultrasonic flow meters are ideal for water and other liquids. Clamp-on ultrasonic flowmeters provide high accuracy at both low and high flow rates, save time without pipe cuts or process downtime, and are immune to external noise.

The selection of the water meter should consider the working environment of the water meter: such as water temperature, working pressure, working time, measurement range and water quality, etc.

Flowmeter selection refers to the selection according to the requirements of industrial production, according to the five principles of fluid type and instrument performance, fluid characteristics, installation conditions, environmental conditions and economic factors.

Many times when we measure the flow, we tend to use the more convenient hand-held ultrasonic flowmeter, because the hand-held flowmeter has high accuracy and is a contact measuring instrument, so we should also pay attention to the operating specifications and a lot of attention when operating. Therefore, today I will talk about the precautions for using a hand-held flowmeter.

It is a metering instrument to continuously measure, record and display volume of water flowing through sensor by use of ultrasonic time difference method.
