Abstract: check the inserted into the meter scale several methods of information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Check the insertion of flowmeter several methods: 1, the flow rate meter method called meter method, is only checkpoint flow pattern plug-in flow sensor measuring head, the measuring head as a way to a meter to check. For the frequency output type measuring head ( Such as insert. More flow meter manufacturers choose model price quote you are welcome to inquire, here is a check inserted into the meter scale several methods of this article for details. Check the insertion of flowmeter several methods: 1, the flow rate meter method called meter method, is only checkpoint flow pattern plug-in flow sensor measuring head, the measuring head as a way to a meter to check. For the frequency output type measuring head ( Such as insert turbine and plug-in vortex street flowmeter) , first of all, in the calibration device instrument of measuring head coefficient have been measured, and then according to the application field of fluid and the pipe conditions to determine the velocity distribution coefficient. Meter method has many advantages, it should be point flow pattern insert flowmeter calibration of the main methods, should be widely used. 2, meter calibration device calibration method and calibration method is: will flow meter measuring head firmly fixed in the measurement of the car, car on the track on either side of the sink mobile measurement standard speed movement speed is water, change velocity and instrument signal, the relationship between various speed obtained to determine the flow rate of the measuring head meter coefficient. If the meter manufacturers do not have straight line slot and low speed wind tunnel, you can also use pipe flow standard device for calibration of measuring head, but must be sure of velocity distribution coefficient in the test section of the pipe flow standard device and blocking coefficient. 3, flowmeter flowmeter is for the entire plug-in flow sensor, including measuring head, insert rod, insert the agency, translator and calibrate the measuring pipe, namely the insert type flow meter as a full tube flowmeter calibration instrument coefficient is obtained on flow standard device. So the calibration equipment and methods and full tube flowmeter are exactly the same. Here no longer. 4, current meter meter zui big advantage is the only real flow to calibrate the instrument coefficient of measuring head, and calibration of measuring head can be small and medium-sized equipment, do not need to build large flow standard device, therefore, as the construction costs in check device and instrument daily calibration cost is low. Meter method is used to check the insert flowmeter is various kinds of large diameter flowmeter production cost of the flow meter with low operation cost zui. And calibration plug flow meter by meter method, makes the production cost of instrument is high, for some large diameter instrument even can not check at present. Into the source of instrument as a quality brand flow meter manufacturer, the main products: sewage flowmeter, electromagnetic flowmeter, steam flow meter, gas meter, turbine flowmeter, ultrasonic flowmeter, balance flow meter, such as steam flowmeter, professional custom, the good faith bargaining!
