Why is there a distance between the top ten and the bottom five (even
) when installing the flowmeter on the pipeline? The reason is to make the fluid stable in order to measure accurately.
2. Whether the flowmeter is in the top 5 and bottom 3 or in the top 10 and bottom 5 depends mainly on the measurement requirements.
.
1、 Specifically, the top 5 and bottom 3 indicate that there needs to be a straight pipe section with a length of 5 times the pipe diameter in front of the flowmeter, while there needs to be a straight pipe section with a length of 3 times the pipe diameter behind the flowmeter. The top ten and bottom five indicate that there needs to be a straight pipe section with a length of 10 times the pipe diameter in front of the flowmeter, and a straight pipe section with a length of 5 times the pipe diameter behind the flowmeter.
2、 The installation requirements of front 5 and back 3, front 10 and back 5 of the flowmeter are both designed to ensure that the flow state of the fluid in the flowmeter is stable and stable, thereby improving the accuracy of measurement. The requirements for the top 5 and bottom 3 are relatively low, while the top 10 and bottom 5 are more stringent standards. In pract
3. What are the types of mass flow meters?
4. Why is the installation position of the water flow meter 10 times the pipe diameter before and 5 times the pipe diameter after, and what is the calculation basis ..
The first 10 times the pipe diameter and the last 5 times the pipe diameter refer to two pipe bends that are closed at the front and back of the measuring point, and the two bends are in the same plane. The length of the straight pipe section between the two is equal to 15 pipe diameters. Except for volumetric flow meters, common flow rates usually require this requirement (the straight pipe section required for differential pressure instruments is relatively long), and this requirement is mainly obtained through experiments. The purpose is to eliminate the adverse effects of rotational flow and disturbed fluid caused by bends on the measurement accuracy of the flowmeter through a certain straight pipe section, in order to achieve the best measurement effect. If it is a valve in front of the flowmeter, a longer straight pipe section is required.
