Mass Flow Controller theory

In the case of mass flow control, the output signal is continuously compared with a setpoint signal from a voltage source. Any deviations between setpoint signal and measured signal are translated into a solenoid control valve adjustment until the two signals are identical.

Only Bronkhorst offers so many different models of control valves, not just suitable up to pressures of 700 bar, but also capable of coping with high and extremely low differential pressures, and with high flow rates.
