Mass flow controlling device

A mass flow controller (MFC) is a device used to measure and control the flow of liquids and gases. A mass flow controller is designed and calibrated to control a specific  type of liquid or gas at a particular range of flow rates. The MFC controller can  be given a setpoint from 0 to 100% of its full scale range but is  typically operated in the 10 to 90% of full scale where the best  accuracy is achieved. The device will then control the rate of flow to  the given setpoint. MFCs can be either analog or digital.   A digital flow controller is usually able to control more than one  type of fluid whereas an analog controller is limited to the fluid for  which it was calibrated. 


All mass flow controllers have an inlet port, an outlet port, a  mass flow sensor and a proportional control valve. The MFC is fitted  with a closed loop control system which is given an input signal by the  operator (or an external circuit/computer) that it compares to the value  from the mass flow sensor and adjusts the proportional valve accordingly to achieve the required  flow. The flow rate is specified as a percentage of its calibrated full  scale flow and is supplied to the MFC as a voltage signal. 


Mass flow controllers require the supply gas or liquid to be  within a specific pressure range. Low pressure will starve the MFC of  fluid and cause it to fail to achieve its setpoint. High pressure may  cause erratic flow rates. The MFCs are typically factory calibrated using dry nitrogen gas.

Mass flow metering device

A thermal based mass flow meter is a device that outputs a voltage proportional to the mass flow rate it measures, but does not control or restrict the flow based on an input signal. It therefore does not require a piston / valve downstream and operates at relatively low differential pressures.
