Selection of flow meter accuracy
Thread Content
When selecting a flow meter, in order to maintain the injection pressure of the medium behind it, there are requirements regarding the pressure loss caused by the flow meter, which must not exceed 500 Pa. What should be done if the accuracy of the flow meter does not meet these requirements? What is the basis for choosing the accuracy grade?
This design involves quite a number of parameters, which are related to things such as pipe diameter, flow rate, pressure, and so on; it’s not possible to discuss it simply without any context.
You mentioned two requirements that the process imposes on meters: pressure drop and accuracy. These two requirements are not contradictory; it is possible to choose a flow meter with a low pressure drop but high accuracy, and specific operating conditions are also necessary. Based on the design specifications and the recommended types of instruments, there is certainly a suitable instrument available; of course, price is also a factor to consider.
1. There is absolutely no relationship between the pressure loss of a flow meter and its accuracy.......... 2. “What should be done if the accuracy of a flow meter does not meet the required standards?” ” Answer: One should drink porridge. 3、:lol Hehehe. Choose a flow meter with low pressure loss, such as a Pitot tube flow meter – that’s the right choice. .
