Often, when we measure flow, we tend to use the convenient handheld ultrasonic flowmeter. This is because the handheld flowmeter has high accuracy and is a contact-type measuring instrument. Therefore, when operating it, we also need to pay attention to the operation norms and many precautions. So today, let's talk about what precautions should be taken when using a handheld flowmeter.
1. When using a handheld ultrasonic flowmeter, it is important to note that the ultrasonic flowmeter is most afraid of bubbles. When there are impurities or bubbles in the heating network, it will affect the final strategy result. Therefore, measurement should be avoided in places with impurities and bubbles. Of course, it is also possible to remove these bubbles and impurities first before measurement, otherwise it will affect the result.
2. For ultrasonic measuring instruments, since they are rather concerned about impurities affecting the final measurement results, the turbidity of the liquid can be measured by the time difference method, and then the areas with turbidity less than 2000 can be taken as the measurement targets. Moreover, different handheld ultrasonic flowmeters have requirements for the applicable range of water quality, and some measuring instruments can measure in areas with high impurity turbidity. The appropriate measuring instrument should be selected.
3. There are many points to note when choosing a handheld ultrasonic flowmeter. For instance, it is necessary to ensure the quality of the battery to prevent it from being unusable due to battery wear and tear. Also, it is advisable to have the habit of fully charging the device after each use. Moreover, it is recommended not to use the device during the charging process, as this can cause significant damage to the battery. Moreover, after regular use, simple cleaning work should be done, and it should be stored in a place that is not exposed to direct sunlight and where the air humidity meets the standard.
The points mentioned just now are the precautions for using handheld ultrasonic flowmeters. Since this type of ultrasonic flowmeter is very precise, it is necessary to pay attention to the regular maintenance work. Moreover, when operating, it should be used in accordance with the operation specifications. Only in this way can the measured data be accurate enough.
