Target Flowmeter Mounting Requirements - Focus on Microfluidic Control Technology

Target flowmeter installation requirements
Before the target flowmeter is installed, the user shall provide a packing list against the manufacturer to check compliance with the requirements and perform a preliminary inspection to confirm whether the product has been damaged due to transportation and other human factors.

1. The flange of the target flowmeter is based on the GB/T standard, and other industry standards and special requirements flanges can be provided according to user requirements.
2. To ensure the accurate measurement of the target flowmeter, it is generally required to set the forward and backward straight sections to be 5D before and after 10D. At the same time, in order to ensure on-line maintenance of the target flowmeter in the ground, a bypass pipeline shall be provided under the conditions permitting. l
3. The target flowmeter is generally installed horizontally, and its basic installation is as follows:
What are the installation requirements of the target flowmeter?
1.2.3, respectively, for the front and rear valves and bypass valve; 4 for the flowmeter, L ≥ 10D and L ≥ 5D, respectively, before and after the straight pipe length greater than 10D and 5D. (D-target flowmeter nominal diameter mm) l
4. When the target flowmeter is installed vertically, the flow direction of the medium is preferably from bottom to top. l
5. It is forbidden to install valves, elbows, etc. at the front and rear ends of the target flowmeter to greatly change the components of the fluid flow state, so as to seriously affect the accuracy of the flowmeter. l
6. During installation, avoid strong impact on the instrument, causing damage to the instrument itself and severe drift of the zero point.
7. The target flowmeter and the pipeline before and after the connection should be as coaxial as possible to reduce the ground error caused by the liquid state mutation. l
8. The installation direction of the target flowmeter is consistent with the flow direction of the liquid to be measured in the direction indicated by the arrow on the measuring tube (outer cavity).
9. For instruments installed in open air, certain measures should be taken to avoid direct erosion by rainwater.
10. For target flowmeters that require remote signal transmission, users must configure 24VDC power supply.
