The main reasons for the large measurement error of the target flow meter

Abstract: The main reasons for the large measurement error of the target flow meter are provided by the excellent flow meter and flow meter manufacturers and quotation manufacturers. The main reason for the large measurement error of the target flowmeter is that the indication value of the target flowmeter increases abnormally during the working process, and the measurement error is large. There are many reasons for this phenomenon. The main reasons are as follows: a. Target There are filaments hanging on the film and the target rod. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following are the main reasons for the large measurement errors of target flowmeters. The main reason for the large measurement error of the target flowmeter is that the indication value of the target flowmeter increases abnormally during the working process, and the measurement error is large. There are many reasons for this phenomenon. The main reasons are as follows: a. Target There are filamentous and ribbon-shaped debris hanging on the film and target rod; treatment method: refer to the method of handling debris. b. Under the condition of high junction, the target plate and the target rod have serious junction, which increases the projected area of ​​the target plate of the force-bearing element along the axis of the measuring flow tube, that is, the annular flow area between the target plate and the measuring flow tube decreases, and then Under the same flow rate, the force of the sensor increases, which eventually leads to an abnormal increase in the flow indication value; treatment method: remove the transition parts, and use tools to remove the target piece, the target rod, and the masonry on the inner wall of the measuring flow tube. c. During installation, the relative concentricity of the target flowmeter and the connecting pipe is greatly dislocated, and the sealing gasket is not concentric, thus forming a throttling resistance piece, which greatly affects the flow state of the liquid, gas and dust to be measured; treatment method: adjust the installation state. d. The straight pipe section before and after the target flowmeter is too short, and elbows, valves, etc. are directly installed in front of the target flowmeter, which greatly interfere with the liquid, gas, and dust flow components under test; treatment method: install according to the requirements of the manual or On-site real-flow calibration of the target flowmeter. e. Bypass pipeline leaks; treatment method: check and replace the bypass pipeline. f. The target piece is wrapped with ribbon-shaped debris, which increases the force of the target piece; treatment method: refer to the previous method for handling debris.
