Four common problems of electromagnetic flowmeter, Shanghai porcelain city instrument co., ltd. is the world's leading instrument manufacturer, because of the excellent quality, with a good reputation to occupy the market quickly, in the hearts of many customers, porcelain city is the pronoun of flowmeter.Our goal is to provide high quality flow meters and excellent solutions for your engineering applications.
A, intelligent pressure transmitter in the application of some common fault analysis, some common fault is the result of a damaged electronics instrument panel itself, some of them are due to improper use, improper installation, environmental standards, factors such as fluid mechanics characteristics of common failures, such as display volatility, precision even dashboard damage reduction, etc.It can be generally divided into two types: intelligent pressure transmitter meter in the installation of the common fault and the normal operation of the common fault.
Common faults during the adjustment period common faults are expected to occur during the adjustment stage of the instrument panel installation and will not occur again once eliminated under the same standards.Common failures during the adjustment period are usually caused by improper installation, environmental impact, and fluid mechanical characteristics.
Installation is usually a common fault caused by the incorrect installation position of intelligent pressure transmitter sensor.Or installed in the vertical pipe from the top down, may appear empty;Or the sensor after no back pressure, fluid mechanics immediately into the atmosphere to produce accurate measurement of the tube is not full tube.
Common faults in operation period common faults in operation period are common faults that occur after the intelligent pressure transmitter meter is adjusted and all works normally for a period of time. Common faults in operation period are generally caused by the internal wall adhesion layer of the flow sensor, lightning strike and changes in environmental standards.
Because the intelligent pressure transmitter meter is often used to accurately measure the fluid dynamics of dirt, after a period of operation, the adhesive layer often accumulates in the inner wall of the sensor and causes common faults.These common failures are often due to the adhesion layer conductivity is too large or too small.If the attachment is cable sheath, the electrode circuit will be broken and the instrument panel cannot work properly.If the conductivity of the attachment layer is significantly higher than that of the fluid mechanics, the electrode circuit will be short-circuiting and the instrument panel will not work properly.Therefore, the intelligent pressure transmitter meter should be removed in time to accurately measure the adhesion of the scaling layer inside the tube.
Four, in the application of the process of intelligent pressure transmitter, all kinds of common failures may occur, but in general can put all of the common faults boils down to two kinds, namely the adjustment period of common failures and operational phase of the common faults, as long as we are in daily work time pay attention to these two kinds of common failures, and to solve well, I believe that the intelligent pressure transmitter must be able to play its proper role.
