The solution of the flow meter improper operation and installation

Abstract: the flow meter on the solution of the improper operation and bad installation information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Traffic flow meter on the solution of the instrument operation is not good and bad installation common failures, in the application, including improper operation and flow disturbance and bad installation; Produce air-pocket and will have bubbles in the liquid; Contained in gas condensate; Wear and deposition, and so on. These mistakes. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the solution of the flow instrument operation is not good and bad installation article details. Traffic flow meter on the solution of the instrument operation is not good and bad installation common failures, in the application, including improper operation and flow disturbance and bad installation; Produce air-pocket and will have bubbles in the liquid; Contained in gas condensate; Wear and deposition, and so on. These failures often result in a flow meter is not allowed or failure. Users often from material balance, process system and the historical value comparison or with other reference flow measurement value comparison, feeling used flowmeter measurement is accurate, however instrument to check on flow standard device, with a few is error (instrument itself Such as debugging setting error) Outside that most of the instrument is normal. The reason most often belongs to the instrument installation medium and the pipe with mixed with interphase ( If there is condensation in the gas liquid droplets, in bubbles in the liquid) From the aspects such as the error. Good bad installation, improper operation and arrangement of common are: 1) Standard orifice of the acute Angle is not welcomed in flow. 2) Sealing gasket between instrument and pipeline diameter dg is less than the pipe diameter dp and meter diameter dm beam. Dg should be slightly bigger than the dm, such as dg3) Eccentric sealing gasket ( Misalignment center) 。 Sealing gasket installation eccentric, cover some of the circulation area, make the velocity distribution asymmetry of serious distortion. Due to the asymmetric flow occurred in the flow sensor imports, the length of straight pipe upstream is zero, the differential pressure type, turbine, and vortex street type, ultrasonic type, target type, such as electromagnetic instrument measurement error. For example dn50mm electromagnetic flowmeter liner eccentric 10 mm, the measurement error is as high as 4% ~ 10%. 4) The meter is in the wrong direction of flow. 5) Will be for vibration interference are sensitive instrument installed in vibration of the pipes. 6) Lack the necessary protective accessories. These defects are well known or instrument factory should be avoided. By operating personnel without strict training, however, lack of knowledge and did not pay more attention to this kind of mistake. Eccentric sealing gasket inside diameter is too small or install while on the displacement, the float type, coriolis mass type instrument, such as flow value has no effect or little effect, but may increase the risk of additional pressure loss. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.

are an important part of the society and they come in handy in any place where there are insertion ultrasonic flow meter in need of rosemount vortex flow meter.
