On-line verification method of LDE flow meter and V-cone flow meter

Abstract: The online verification method information of LDE flow meter and V-cone flow meter is provided by the excellent flow meter and flow meter production and quotation manufacturers. Flow meters such as LDE flowmeters and V-cone flowmeters cannot be calibrated regularly in some places of use. For example, large water pipelines are not allowed to be shut down. Compare or. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following is the details of the online verification method of LDE flowmeters and V-cone flowmeters. Flow meters such as LDE flowmeters and V-cone flowmeters cannot be calibrated regularly in some places of use. For example, large water pipelines are not allowed to be shut down. There are three different levels of operation, such as comparison or verification. Based on years of field operation experience, the technical staff of Jinhu Xudong Instrument Factory summarizes and applies the current online calibration and online comparison, and optimizes and improves the evaluation and verification of flow meters used by electromagnetic flowmeters and V-cone flowmeters. method. The flow value of electromagnetic flowmeter and V-cone flowmeter is usually calibrated on the flow standard device of the flow laboratory of the manufacturer such as Xudong Instrument Factory to transmit the value. However, when the on-site flow and use conditions deviate from the reference working conditions at the time of calibration, in order to detect the on-site conditions, that is, the measurement accuracy of the measurement system (including flow meters, front and rear connecting pipes, medium flow status, etc.), or custody transfer measurement requirements Short interval period verification, and places where offline calibration of deactivated pipelines is not allowed, online calibration is required. The online calibration of flow instruments such as electromagnetic flowmeter and V-shaped cone flowmeter is to temporarily connect the fluid flowing through the instrument to be calibrated to a fixed (or mobile) flow standard device or standard measuring instrument for comparison under on-site measurement conditions. In addition to the highest level of online calibration, there are two levels of online comparison and online verification. The working method of online comparison of flow meters and“calibration”similar, but not in some ways“calibration”regulations, the requirements are relatively low, such as only compared with reference gauges of a similar accuracy class. On-line verification of flow meter is an indirect inspection method to evaluate or verify that the performance of the meter, such as the flow measurement value, still maintains or exceeds the range of the original calibration performance, and provides a basis for whether it can still be used or needs further inspection. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
