Introduction to analysis of sewage flow meter scale for daily use and maintenance method

Abstract: introduction to the analysis of sewage flow meter scale daily maintenance method in the use of the information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Introduction to analysis of daily maintenance method in the use of sewage flowmeter flow meter is one of the categories of instruments for process automation instrument and apparatus, it is widely used in metallurgy, electric power, coal, chemical industry, petroleum, transportation, construction, textile, food, medicine,. More flow meter manufacturers choose model price quote you are welcome to inquire, here is a introduction to analysis of sewage flow meter scale daily maintenance method in the use of the article for details. Introduction to analysis of daily maintenance method in the use of sewage flowmeter flow meter is one of the categories of instruments for process automation instrument and apparatus, it is widely used in metallurgy, electric power, coal, chemical industry, petroleum, transportation, construction, textile, food, medicine, agriculture, environmental protection and People's Daily life and so on each domain of national economy, is the development of industrial and agricultural production, save energy and improve the quality of our products and improve the economic benefit and the management level of the important tools in the national economy occupies an important position. But the user must also pay attention to the daily maintenance is important to note what respect? 1: manual zero method: refers to the use of multimeter for differential pressure table to send manual zero, a cop pressure transducer zero drift slightly can use this method, the approach is as follows: differential pressure transmitter has positive and negative two signal lines, and tear down, one of the multimeter in 4 - On 20 ma dc gear, string, multimeter to differential pressure transmitter has a time zero screw ( Marked with zero is zero button) Clockwise debugging, current increase, counterclockwise to reduce, when the multimeter displays is required 4 ma zero to set at this time. 2: condensate valve switch order ( Mainly for steam) : when the normal operation of the three intermediate valve valve group is closed, valve for open on both sides, if need to drain or condensation, closed the valve on both sides first, and then open the valve on the middle, zui to root after sewage drain valve open, if after condensation completely, want to close the valve on the middle, in then slowly open the valve on both sides, is the normal operation of the system. 3: to measure the medium for steam, it should be online adjust zero, because condensation when installation disk may have a little difference in height, to measure the fluid velocity is small, the height difference have bigger influence on the traffic at this time. ( 1 cm water column for 100 pa) Maintenance methods: 1, the probe should be cleaned regularly vortex flowmeter, was found in the examination and individual probe test holes have been contamination jams, and even be plastic wrapping, affected the normal measurement. And eastern chemical works lack calibration method and ability, can only be out of calibration, the influence of process operation, should be removed from the pipeline vortex street to send up to 5, and 6 days of calibration time, process is hard to meet, to determine the coefficient K. Should be drying time, regularly and moistureproof processing. Because at the end of the probe itself and moistureproof processing, affect running after be affected with damp be affected with damp. 4, regularly check grounding and shielding case, eliminate the interference. The problem is due to interference by sometimes instructions. 5, meter data management should cause enough attention, to facilitate the future work. Key words: sewage flow meter, fujian sewage flowmeter, electromagnetic flowmeter, fujian province, sewage flow meter, water meter, fission electromagnetic flowmeter, more than large diameter electromagnetic flowmeter is all there is in this article, you are welcome to inquire me factory flowmeter selection, quotation, etc.
