1. In the measurement of pipelines and old industrial and mining, try not to use 2 sound layer (V method) to install the sensor, you should first select 1 sound layer (Z method), this installation method, the ultrasonic wave emitted by the ultrasonic flowmeter flow sensor It is easy to be received by the measured flow sensor, and the signal strength of the flow meter host is guaranteed, and the high-precision measurement value can be guaranteed.
2. When measuring new pipelines, when encountering paint or crossing zinc pipelines, the surface of the pipeline can be treated with roving first, and then treated with fine yarns to ensure smooth, flat, ultrasonic wave flow sensor installation points. The flowmeter's flow probe is in good contact with the outer wall of the pipe being measured.
3. When the pipeline is in a vertical upward direction, if the fluid in the pipeline flows from bottom to top, it can be measured. If the liquid is a top-down flow, this pipeline is not suitable for flow data collection.
4. In addition, before collecting the flow data of a pipeline, it is necessary to measure the outer circumference of the pipeline (using a tape measure), the wall thickness (using a thickness gauge), the temperature of the outer wall of the pipeline (surface temperature measuring instrument), etc., because many The accuracy of the measurement is not accurate, not because of the problem of the instrument itself, but by measuring the so-called parameter deviation problem of the field staff. Believe in your own eyes and don't trust your ears.
5. Choose a suitable ultrasonic flowmeter. There are many types of ultrasonic flow meters. How to choose an ultrasonic flow meter? Many people who call the technical department of Shanghai Senyi Intelligent Instrument Co., Ltd. will say, “I will give you a lot of things to communicate with your company, thank you!†This is because the technical staff of Shanghai Senyi Intelligent Instrument Co., Ltd. Adhering to the results of the Senyi concept! The technicians of Shanghai Senyi Intelligent Instrument Co., Ltd. will not think that they should promote their products. Instead, they recommend products according to the user's working conditions and practical applications, and recommend ultrasonic flowmeters suitable for users. Many times, this flowmeter is in Shanghai. There are no sales in Senyi Intelligent Instrument Co., Ltd. So the caller will feel and thank you.
In the selection of ultrasonic flowmeters, it is still based on the actual conditions of each working condition to make choices, with working conditions, and interested friends can also go to technical exchanges.
6. When operating the ultrasonic flowmeter, be sure to follow the requirements of the flowmeter manufacturer and standardize the operation. Do not "I think it can be operated like this" mentality, or seem to find new laws, in fact, many irregular operations are based on the accuracy of the ultrasonic flowmeter. Such as: coating coupling agent, Z method to install through the center line.
7. For measuring special media, such as natural gas, compressed air, etc., you need to choose carefully. If the gas pressure in the aisle is less than 8KG, you should not use ultrasonic flowmeter as the measurement basis, but should use mechanical instrumentation.
8. For the pulse flow conditions, select the appropriate ultrasonic flowmeter. Select the ultrasonic sampling time interval and the ultrasonic flowmeter smaller than the pulse frequency interval. Otherwise, the actual fluid flow rate has changed. Your ultrasonic flowmeter has not yet Reflected, the resulting error is very large.
9. Regarding some conventional installation precautions, the choice of installation points will not be described here. I believe that practitioners who have contacted ultrasonic flowmeters should be very clear. If you are not sure, you can call Shanghai Senyi Intelligent Instrument Co., Ltd. to communicate. And consulting!
