Bürkert Type 8710 can control the gas mass flow with a sensor component that has no contact with the gas.
A comparison is done in the digital control electronics between the gas measurement value given by the sensor and the predefined set point as per the signal. In case there's a control difference, a PI-control algorithm will modify the control value output to the proportional valve.
This allows maintenance of mass flow at fixed value or following a predefined profile, irrespective of pressure or any other system variations.
An option is available to calibrate Type 8710 for two separate gases, with the user having the ability to switch among the two gases.
