Electromagnetic flowmeter installation requirements 1, electromagnetic flowmeter can be installed in a vertical pipe, tilt the pipes and horizontal pipe, straight pipe upstream of not less than 5 pipe diameters downstream straight pipe of not less than three times the diameter of the pipe. 2, electromagnetic flowmeter housing, etc. should be done between the measured fluid and pipe connection flange three potential connection, and should be grounded; if there is a strong magnetic field around should take measures against noise. 3, when installed in a vertical pipe, the flow of fluid to be measured should be bottom-up Vortex Flow Transmitter wholesale, when installed on a horizontal pipe, two measuring electrodes above and below the positive should not be in the pipeline. Parallel standard table basic principle accuracy gas vortex flow sensors detecting apparatus generally in a horizontal 0.5 ~ 1.5, and is unable to direct as Vortex Flow Transmitter 0.5 standard sensor used when using only standard flow sensor A limited test curve segment. Standard flowmeter calibration accuracy can be improved. Also subject to test the accuracy of the meter can be improved. Within this limited measurement range of the meter factor K relative error will be less than full scale error meter factor. The results show that if the turndown ratio of 2: 1 or 3: 1, in the fixed-point calibration to meet the requirements, so using the sensor standards, establish a gas flow device is feasible. Parallel is limited by several standard measurement range of the meter in parallel instead of a single large range of standard flow meter Vortex Flow Transmitter retail, limit the use of high-precision low volume flow meter standard flow meter calibration standards make traceability problems simplified. Establish a comparative measurement system based on the way to the standard meter as the standard device, the gas in the same time interval between successive meter and was seized by standard flow meter, flow value comparison between the two, in order to determine the subject flowmeter The measurement of performance. At the same time interval technique, passing through all the standard gas mass flow sensor shall be equal to the quality of the school by the gas flowing through the table. According to the ideal gas equation PV = nRT known quality, as long as the measured temperature and pressure of the gas flow and working conditions of the time you can find to flow through the calibration of mass flow; according to the detected by the pressure and temperature calibration and pulse number can be calculated by the constant flow of calibration.
