Gas flow performance

When selecting sensors for gas applications, measurement accuracy is a function of fluid mass flow rate independent of operating

temperature, pressure, or composition. However, pressure drop through the sensor is dependent upon operating temperature,

pressure, and fluid composition. Therefore, when selecting a sensor for any particular gas application, it is highly recommended that

each sensor be sized using the Micro Motion product selector, available at www.micromotion.com
