Intelligent ultrasonic flowmeter

Intelligent ultrasonic flow meters (energy meters) are widely used in the measurement of system flow (energy) consumption in refrigeration, heating, heat exchangers, refrigerators, boilers and other industries. The flow measurement of the intelligent ultrasonic flowmeter (energy meter) is simple and convenient. Just select a suitable installation point, enter the pipeline parameters at the installation point on the host, and then set the intelligent ultrasonic flowmeter according to the sensor installation distance provided by the intelligent ultrasonic flowmeter host. The type ultrasonic flowmeter sensor is installed on the surface of the pipeline and connected to the host with a special cable for the intelligent ultrasonic flowmeter to complete the flow measurement. Because of its simple and intelligent measurement method without breaking the tube, it has been sought after by everyone. Today, the editor will introduce to you the installation guide of intelligent ultrasonic flowmeter. The installation guide for the intelligent ultrasonic flowmeter is as follows: 　　 (1) The installation guide for the intelligent ultrasonic flowmeter should understand the on-site situation before installation, including: 　　1, how far is the distance between the sensor and the host of the intelligent ultrasonic flowmeter; 　　2, pipe material , Pipe wall thickness and pipe diameter; 　　3, pipeline age; 　　4, fluid type, whether it contains impurities, bubbles, and whether the pipe is full; 　　5, fluid temperature: plug-in intelligent ultrasonic flowmeter sensor needs to confirm the pipeline pressure; 　　6, intelligent type Whether there are interference sources at the installation site of the ultrasonic flowmeter (such as frequency conversion, high-voltage cable field, etc.); 　　7, the temperature of the four seasons where the host of the intelligent ultrasonic flowmeter is placed; 　　8, whether the power supply voltage of the intelligent ultrasonic flowmeter is stable; 　　9, whether the customer Intelligent ultrasonic flowmeters are required to provide remote signals and types; 　　According to the on-site conditions provided above, manufacturers can prepare intelligent ultrasonic flowmeters for on-site conditions, and special models can also be made if necessary. (2) Choosing the installation location of the intelligent ultrasonic flowmeter. Choosing the installation pipe section has a great influence on the test accuracy of the intelligent ultrasonic flowmeter. Therefore, the pipe section should avoid interference and eddy currents, which have a greater impact on the measurement accuracy of the intelligent ultrasonic flowmeter. Generally, the pipe section should meet the following conditions: 　　 1. Avoid installing intelligent ultrasonic flowmeters on water pumps, high-power radios, frequency conversion, that is, where there is strong magnetic field and vibration interference. 2. The selection of pipes should be uniform and compact, easy to intelligent ultrasonic flowmeter ultrasonic Transmission pipe section; 　　3. There must be a long enough straight pipe section. The upstream straight pipe section of the intelligent ultrasonic flowmeter installation point must be greater than 10D (note: Du003ddiameter), and the downstream must be greater than 5D; 　　4, the intelligent ultrasonic flowmeter installation point There should be a 30D distance upstream from the pump; 　　5, the fluid should be full of the pipeline; 　　6, there should be enough space around the pipeline to facilitate the operation of the intelligent ultrasonic flowmeter by the on-site personnel; 　　(3) determine the installation method of the intelligent ultrasonic flowmeter There are generally two ways to install the probe, namely the Z method and the V method. Normally: 　　When the pipe diameter D is greater than 200mm, use the Z method and use the V method when the pipe diameter is less than 200mm. However, when D is less than 200mm and the site situation is one of the following conditions, the Z method can also be used for installation: 　　1, when the fluid to be measured When the turbidity is high, the signal cannot be received by the V method or the signal is very weak; 　　2, when the inner wall of the pipeline is lined; 　　3, when the pipeline service life is too long and the internal piping scale is serious; 　　 (4) seeking intelligent ultrasonic The installation distance of the flowmeter, determine the position of the intelligent ultrasonic flowmeter probe 1, input the pipeline parameters into the intelligent ultrasonic flowmeter, select the probe installation method, and get the installation distance of the intelligent ultrasonic flowmeter; (for specific input pipeline parameters, please refer to the manual)　　2 On a horizontal pipeline, you should generally choose the middle of the pipeline to avoid the top and bottom (the top may contain bubbles and the bottom may have sediment); 　　3, V method installation: first determine one point, and measure the other in the horizontal position according to the installation distance point. Z method installation: first determine a point, measure another point in the horizontal position according to the installation distance, and then measure the symmetrical point of this point on the other side of the pipeline; 　　 I have seen so many points of attention for the installation of intelligent ultrasonic flowmeters, everyone Do you have a clearer understanding of intelligent ultrasonic flowmeters?
