Instrument installation considerations

by:Sincerity     2021-01-06
Abstract: the instrument installation note information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. 1, meter hole should be avoided in forming hole in the pipeline. 2 in the junction box, the field instruments, the grounding of different grounding systems can't meet, all instrument shielded wire should be separate connection shielding layer from top to bottom, it is forbidden to screw connection block up and down together. 3, stainless steel pipe. More flow meter manufacturers choose model price quote you are welcome to inquire, is instrument installation considerations article details below. 1, meter hole should be avoided in forming hole in the pipeline. 2 in the junction box, the field instruments, the grounding of different grounding systems can't meet, all instrument shielded wire should be separate connection shielding layer from top to bottom, it is forbidden to screw connection block up and down together. 3, stainless steel pipe, it is forbidden to electricity, gas welding, cutting and open hole, plasma or mechanical cutting, opening should be adopted. 4, different grounding system of instrument instrument line or share a rack with the power cord, application of metal plate. 5, dashboard, cabinets, boxes, the installation of the machine and the processing is strictly prohibited in the gas welding method, fixed installation should not adopt welding way, hole open Kong Yi using mechanical method. 6, drain valve and under appropriate increase transmitter valve leakage of the tube cap ( Especially in the explosion-proof area) 。 7, note straight pipe before and after the meter length. 8 for grounding requirement of electromagnetic flow meter, such as quality grounding should be conducted according to the instructions. 9, instrument using copper gaskets, without annealing treatment, should be annealed before use, and pay attention to all kinds of gasket material allowable temperature, medium and pressure conditions. 10, instruments are in a difficult to observe, overhaul location, at party a's approval, change or add platform position. Among 11, instrument line joints shall be strictly forbidden, such as in special circumstances to party a's approval, and make the hidden records, compensation conductor joint welding or pressure should be adopted. 12, stainless steel joint should be pickling and passivation, and processing. 13, galvanized, aluminum alloy cable tray are strictly forbidden to electricity, gas welding, cutting and open hole, toothless saw and special core should be adopted, such as mechanical cutting and opening. Process piping welding, grounding line should avoid instrument noumenon, prevent the earth current flows through the instrument of ontology into the ground, and damage the instrument. 14. Process of welding, avoid earth current flows through the single and double flange instrument of capillary pressure tube. 15. Pay attention to the installation of the flowmeter throttle device take pressure direction. 16. Stainless steel lead pressure pipe roasted is forbidden; Are strictly prohibited to bring pressure pipe heat flat. 17. Instrument of pressure pipe, air duct, threading pipe installation position, should avoid to interfere with the process operation in the future, to avoid the high temperature corrosion, should be fixed tightly; From the top of threading pipe, the pins should be lower than the lowest inlet side pick up instrument wiring; Threading pipe most low-end should increase drop tee; Near the instrument side should increase Y type or conical explosion-proof seal joint; Instrument main air line lowest place should add coagulation ( Fouling) Valve. 18. To skim instrument, pipe fittings, degreasing treatment should be in strict accordance with the specification, and make the instrument, pipe sealing after degreasing, keeping work, fight was secondary pollution in the process of storage and installation. 19. It is forbidden to direct contact with carbon steel stainless steel piping. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
