Abstract: the integration of electromagnetic flow meter scale manufacturer of technical standards of information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Bidirectional electromagnetic flowmeter measurement system, close the valve in the line, the use of GS8 converter output current of the electromagnetic flowmeter calibration instrument detection integration, check the integration of electromagnetic flowmeter in liquid flow under the condition of the machine zero point, when a given flow rate. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the integration of electromagnetic flow meter scale manufacturer of technical standard article for details. Bidirectional electromagnetic flowmeter measurement system, close the valve in the line, the use of GS8 converter output current of the electromagnetic flowmeter calibration instrument detection integration, check the integration of electromagnetic flowmeter in liquid flow under the condition of the machine zero point, when a given flow rate of 0, flowmeter output current should be: 4. 00mA; Remember the case from filled with liquid. Measurable flow, when a given flow rate 100%, the output current should be: 20. 00mA。 The error of the output current value should be in 1. About 5%. Reverse flow. Test excitation current value converter terminals & other; 7' And & other 8' Between the exciting current is negative in 137 ( 5%) MA scope. Adopt special attention should be paid to the integration of electromagnetic flowmeter in the external environment's influence on the test results: if the excitation line and signal line on the same line pipe laying, excitation and signal lines and high voltage cable parallel, surrounded by large transformer or motor on the observation of the running status of electromagnetic flowmeter with and without mutation or fluctuations have roughly judge integration electromagnetic flowmeter by electromagnetic waves or other stray wave interference or whether there is a bubble in the pipeline. To evaluate the influence of electromagnetic flowmeter accuracy, the assessment is mainly by using the method of visual such as electrode surface layer and the lining have attached sediments, the sediments are electrical conductivity and insulation. Production technology and high quality materials, measuring excitation coil to ground ( Line no. & other; 1' And & other 7' Or & other 8' ) Insulation resistance to judge whether integration electromagnetic flowmeter sensor be affected with damp be affected with damp, measuring electrode contact with the liquid resistance value, indirect assessment element in electrode, lining layer on the surface of the situation. The resistance value should be greater than 20 megohm. Measuring excitation coil resistance, mainly in order to determine whether the excitation coil turn-to-turn short circuit phenomenon, if the resistance value is the same as the factory record, then we will think the coil is good, therefore evaluate the indirect integration electromagnetic flowmeter the resistance value between them should be 1000 ~ 1 megohm, and line no. & other; 1' And & other 2' And & other; 1' And & other 3' The resistance must be symmetrical. Sensor magnetic field strength did not change. The excitation coil resistance in general should be 30 ~ 170 it. To ensure that product performance remains stable in a long time. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
If you are looking for an effective and safe way to take care of insertion ultrasonic flow meter, then mass flow meter electromagnetic flow meter slurry are the best bet.
