Hand-held ultrasonic flowmeter is a necessary instrument for flow detection. It is designed to improve the convenience of measuring flow. It has high measurement accuracy, large turndown ratio, no pressure loss, no moving parts, small size and light weight. It can be completed by installing the sensor on the outer wall of the pipeline. Measurement of flow. Hand-held ultrasonic flowmeters are widely used in tap water, heating, water conservancy, metallurgy, chemical, machinery and other industries. They can be used for production monitoring, flow comparison, temporary detection, and flow inspection. It is an essential tool for flow detection. Especially suitable for flow balance testing and flow monitoring: drinking water, river water, sea water, cooling water, hot water, industrial sewage, lubricating oil, diesel oil, fuel oil, chemical liquids, etc.
Then let's take a look at the use of handheld ultrasonic flowmeters. The installation methods of handheld ultrasonic flowmeters are divided into bracket installation or clamp installation. Clamp-on installation requires the external clamp sensor to be adsorbed on the outer wall to easily complete the flow measurement. The installation is extremely convenient without cutting off the pipe section, the flow rate, low cost and no pressure loss. The fixing method can be fixed with a metal clamp. The bracket installation simplifies the installation process of the ultrasonic flowmeter sensor and shortens the installation time, and there is a scale directly on the bracket, which improves the installation accuracy and has strong corrosion resistance and durability. It is usually fixed with a steel bracket chain. When using the ultrasonic flowmeter, it should be noted that the ultrasonic flowmeter is most afraid of bubbles. When there are impurities or bubbles in the heating network that will affect the final strategic result, we should avoid measuring the places with impurities and blisters. Of course, you can also choose to remove these blisters before the measurement. And impurities, otherwise it will affect the results.
For the ultrasonic measuring instrument, because of the concern that impurities will affect the final measurement result, the time difference method can be used to measure the turbidity of the liquid, and then the time difference method can be used to measure the turbidity of the liquid. Different handheld ultrasonic flowmetershave requirements for the scope of water quality. , Some measuring instruments can be measured in places with high impurity turbidity, so it is necessary to choose a suitable measuring instrument. There are still many precautions when choosing a handheld ultrasonic flowmeter, such as ensuring that the battery is of good quality, to ensure that the battery is not unusable due to battery loss, and there must be a habit of charging after each use, it is recommended not to use it during the charging process This device will cause too much harm to the battery. After normal use, simple cleaning should be done, and it should be stored in a place free from the sun and the air humidity reaches the standard.
