MEASURING VOLUMES WITH GAS MASS FLOW SENSORS

The two major specifications when selecting a mass-flow sensor are total uncertainty and the response time of the measurement. If the flow rate will vary, it is important to use a sensor with good accuracy over that range. It is best to select a mass-flow sensor that gives a percent of reading rather than a percent of full scale sensor.
