Sensor Selection vortex flow sensors Unlike other flow sensors. Each caliber vortex flow sensors flow range is compressed air metering meter wholesale 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 hours in a narrow range of compressed air flow sensors measure the Principle, wide flow range sensor density. 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. The more lost fewer air leak pulse count metering, metering. 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. The impact on the measurement of the pressure loss of heating system, there are a lot of valves and valves, they can change the pipeline pressure. Vortex Flowmeter not mass flowmeter, which measure the flow rate of steam quality but also with pipes and steam density, and the density is determined by the pressure, the pressure to change the density change. Shihai just open the valve in the pipeline to change the flow rate, these types of cases, so have a great measurement error. To ensure accurate measurement, the meter before the valve to open, valve placed after the flowmeter.
