A gas flow meter is used to measure the volumetric or mass flow rate of various process gases in industrial plants and machinery. The flow rate refers to the speed at which fluid is moving through closed pipes or ducts at a given time. Modern instrumentation & control engineering design needs monitoring of fluid flow rates to optimize the use of gases and improve the efficiency of processes and equipment. Therefore, a gas flow meter device must be calibrated against a reference or a master calibration system. Due to process & environmental conditions flowmeters may have some drift in flowrate readings which needs recalibration periodically for the flow range it is designed for, to achieve the desired accuracy for smooth process operation. Some organizations have an ISO audit system in place which needs recalibration at a specific time frame. Types of Gas Flow Meters Available in Market Various flowmeter technologies are available currently in the market which ...
