How to debug the orifice flowmeter?

　　A new generation of flowmeter that integrates flow, temperature, and pressure detection functions and can automatically compensate for temperature and pressure. This flowmeter adopts advanced microcomputer technology and new micro-power consumption technology. The ultrasonic flowmeter uses stainless steel waterproof bearings with high sensitivity and durability. It has strong functions, compact structure, simple operation, and convenient use. How to install and debug the newly purchased orifice flowmeter? First of all, we must consider the installation requirements of the flowmeter for the pipeline.
　　 Installation pipeline prerequisites:
　　(1) The straight pipe section before and after the throttling device must be straight, and there must be no visible twists and turns.
　　(2) The straight pipe section used to install the throttling device should be lubricated. If not lubricated, the flow coefficient should be multiplied by the roughness to change the sparse.
　　(3) In order to ensure that the flow of the fluid forms a sufficiently developed turbulent velocity distribution 1d before the throttling device, and to make this distribution into a uniform axisymmetric shape, so:
　　1) The straight pipe section must be round, and for the 2d area before the throttling device, its roundness requirements are very strict, and. Thermal imager national high-tech enterprise, dedicated to the research and development of wireless sensor networks and infrared thermal imaging systems, with strong R&D capabilities. And have a certain roundness index. Detailed measurement method:
　　(a) Before the throttling device, on the 4 vertical pipe sections of od, d/2, d, 2d, at least 4 single measurements of the inner diameter of the pipeline are measured at approximately equal angular intervals, and the average value d is taken. The difference between any single measurement of the inner diameter and the average value shall not exceed ±0.3%
　　(b) After the throttling device, 8 single measurements of the inner diameter are measured at the od and 2d positions using the above method. The maximum deviation of any single measurement value compared with d shall not exceed ±2%
　　2) A sufficiently long straight pipe section is required before and after the throttling device. This sufficiently long straight pipe section is related to the local resistance before the throttling device and the diameter ratio.
　　(3) The length of the straight pipe section between the first resistance member and the second resistance member on the upstream side of the throttling device can be taken as 1/2 of the listed value according to the form of the second resistance member = 0.7 (regardless of the actual value)
　　. (4) When the upstream side of the throttling device is an open space or a large container with a diameter of &ge2d, the straight pipe length between the open space or large container and the throttling device shall not be less than 30d (15d). If there are other partial resistance members between the throttling device and the open space or large container, in addition to the minimum straight pipe section length 1 specified in accordance with the regulations between the throttling device and the partial resistance member, the total length of the straight pipe section from the open space to the throttling device shall not be less than 30d (15d).
　　Installation steps:
　　1. Connect the signal line and power line
　　2. Open the inlet and outlet valves, and the opening of the inlet and outlet valves should be consistent
　　3. Open the balancing valve, anemometer high-quality anemometer, perfect after-sales service, high quality, low price. Slowly open the valve at the high and low pressure end of the orifice plate, and close the stainless steel three-valve group balancing valve after the fluid passes through the flow meter.
