Differential Pressure Flow Meters Application Cautions for Differential Pressure Flow Meters Gas applications Gas applications should be designed carefully because changes in operating pressure and operating temperature can dramatically affect the flow measurement. In other words, the gas density can vary significantly during operation. As a result, the differential pressure produced by the flowmeter can also vary significantly during operation. Failure to compensate for these effects can cause flow measurement errors of 20 percent or more in many applications. In these applications, a flow computer can be used to calculate the corrected flow measurement using actual pressure, temperature and flow measurements. |
