是当今世界上具竞争力的流量测量手段，其测量线精度高于1.0%。 Ultrasonic flowmeter is a competitive flow measurement method in the world today, and its measurement line accuracy is higher than 1.0%. Due to the diversity of the industrial site, especially the environment around the pipeline, how to install and debug the ultrasonic flowmeter according to the specific environment has become an important topic in the field of ultrasonic flow measurement. It further fully reflects the advantages of accuracy, reliability and stability of the ultrasonic flowmeter, greatly reducing future maintenance work and even maintenance-free.
Ultrasonic flowmeter installation steps:
(1) Observe whether the pipeline at the installation site meets the first 10d and 5d after the straight pipe section and the distance from the pump 30d (d is the inner diameter of the pipeline). (2) Confirm the fluid medium in the pipeline and whether it is full. (3) Confirm the pipe material and wall thickness. (4) After the first three steps are completed, you can confirm which sensor is used for installation. (5) After selecting the sensor, start to input parameters to the meter body to determine the installation distance. (6) Measure the installation distance accurately.
The outer clip can be optionally installed with the approximate distance of the sensor, and then the active sensor is continuously adjusted to achieve the best match of signal and transmission ratio. Insert and use a special tool to measure the distance between the mounting points on the pipe. This distance is very important. It directly affects the actual measurement accuracy of the meter, so it is best to perform multiple measurements to obtain higher accuracy. Then, make a hole → install the sensor → debug the signal → make waterproof → reorganize the signal cable → clean up the waste such as the on-site wires.
安装是一种优秀的流量测量仪表，它给测量流量带来的方便性和经济性是别的流量计无法比拟的。 The installation of an ultrasonic flowmeter is an excellent flow measurement instrument. The convenience and economy it brings to the measurement of flow are unmatched by other flowmeters. Therefore, the ultrasonic flowmeter should be installed and used correctly according to the requirements of the use conditions and environment of the ultrasonic flowmeter, accurately set the pipeline parameters, and periodically verify or calibrate the ultrasonic flowmeter, so as to ensure the accurate measurement of the ultrasonic flowmeter and extend its service life.
产品使用特点1.超声波流量计有对角和反射两种模式，当反射模式测不出时用对角模式可能能测出，以至于后来我们一直用反射模式。 Ultrasonic flowmeter product features 1. Ultrasonic flowmeters have two modes of diagonal and reflection. When the reflection mode cannot be measured, the diagonal mode may be able to measure, so that we have always used the reflection mode. 2. Ultrasonic flowmeters have high requirements for pipelines, and the insulation layer must be scraped off, otherwise it cannot be measured. When we measure the air-conditioning water system, use a knife to cut off the insulation layer to prevent the sensor, and then stick the cut insulation layer after the measurement. The surface of the pipe is as bright as possible. If it is too rough, it must be polished with sandpaper. 3. Ultrasonic flowmeter is difficult to measure when the fluid in the pipeline is not full, so the measurement position should be as straight as possible, away from elbows, valves and other places Yes, the result is basically unreliable when the signal is too low, generally it is more than 60% or even more. 5. As the readings may vary greatly, the approach we take is to allow the flowmeter to take continuous readings, such as continuously reading for one minute and then taking the average. 6. It is more difficult to measure hot water pipes than cold water pipes. Because the temperature of the hot-water pipe wall surface is high, the couplant is easily made at high temperatures. In addition to the product's own couplant, we have all tried toothpaste. The accuracy and precision of ultrasonic flowmeters need to be improved
