Parallel standard table detector gas flow meter method is to use standard means more gas flow device Guizhou steam flow meter retail, especially in some flowmeter production enterprises to establish this standard more devices. With the accelerated pace of China's urban industrialization, urban environmental protection requirements and city gas, increasing the supply of steam, gas meter sizes are used more and more. Traceable calibration standard table and large-caliber flowmeter existing difficulties became apparent. But if in parallel using the standard way of Guizhou table steam flow meter quote, just use the standard flowmeter calibration curve for a limited segment of Guizhou steam flow meter, standard flowmeter calibration accuracy can be improved. Also it allows the flow meter range of the subject to reach demand. In parallel standards as a gas meter calibration device has been widely used at home and abroad Guizhou steam flow meter companies, such as the widely used domestic gas flow device nozzle method is the use of parallel; 1990s Canada built North America's largest Gas solid flow calibration device is six DN400 and DN200 two turbine flow meter as a standard form to verify DN750 following the various caliber flowmeter. Sensor Selection vortex flow sensors Unlike other flow sensors. Each caliber vortex flow sensors flow range is fixed and can not be adjusted. So it is to choose according to the traffic caliber. Selection should be under conditions of pressure, temperature, make sure to measure the flow range. Then choose to cover this flow range diameter flow sensor. Vapor Density hour traffic in a narrow range of sensors, high density sensor wide flow range. If you choose incorrectly. When the actual flow rate greater than the upper sensor limit, let the other cause the sensor head is damaged, lost missing pulses, less measure. The more traffic over the actual limit. Lost missing pulses, the more less measure. When the actual flow rate is less than the lower limit, the sensor measurement sensor little or no metering. This two cases of long-term use can cause great losses. Guizhou steam flow rates, Guizhou steam flow meter, Sisson Sisson from Guangzhou Automation provides automation control equipment Limited.
