How to install the electromagnetic flowmeter correctly
Electromagnetic flowmeter how to install correctly, electromagnetic flowmeter key for accurate measurement of the flow of good conductivity medium, generally used as a good assistant of intelligent system, industrial automation, the following look at the installation of electromagnetic flowmeter, I hope you will be helpful.
1, first to pipeline control point measurement of open a Φ 60-62 - mm above the hole, the rules around the hole edge is smooth, no burrs and oxygen tumour scar, etc., will be installed a away from the controller and on welding welding it is punched, regulation: make plug-in electromagnetic flowmeter installation pieces below and pipeline inside level;Make sure it doesn't leak.
2. Record the L2 specification, loosen the 3 locking screws of the controller, and pull out the detection rod and detection head for later installation.(note: the customer cannot open the connection between the test head and the insertion lever!)
3. Wrap raw tape around the outer thread above the mounting part and then connect the gate valve to the sealing and locking structure and tighten it on the top.
4. Gradually insert the test rod from the top, tighten the locking nut a little, press down the insert rod to accurately measure L2 and the original record L2 specifications, and then install immediately.
5. Insert deep adjustment: when the electrical level is selected and inserted into the mean water flow, the mean water flow point is about the distance from the wall thickness according to the standard of pipeline flow field
H= 0.25d (D is the nominal diameter of the pipe, that is, 1/4 of the pipe through is inserted into the deep layer). After adjustment, tighten the locking nut with strength and then fix three locking screws respectively.
Warning and attention: because the working pressure in the pipeline has an outward investment attraction to the detection rod, so
For safety is correct, it is best to choose shutdown that is in the pipeline without pressure standard to carry out the installation.
If shutdown is not allowed, it is best to temporarily reduce the working pressure of the pipeline to less than 0.2MPa during installation.
Porcelain city Shanghai instruments co., LTD., the introduction of Germany Siemens numerical control processing center, make the tiny flowmeter is greatly increased, actually has reached world leading level, such as OVAL LSF40, many clients in Japan and the customer to know LSF40 flow range in 0.7 ~ 50 l/H, and porcelain xian CX - M5 - AL can achieve 0.3 ~ 60 l/H, the same 0.5% FS precision, another porcelain city gear is SS316L is qualitative, OVAL gear is plastic.
