which is not in direct contact with the gas itself. The measured value
provided by the sensor (see the description on page 2) will be compared
in the digital control electronics with the predefi ned set point according
to the signal; if a control difference is present, the control value output to
the proportional valve will be modifi ed using a PI-control algorithm. In this
way, the mass fl ow can be maintained at a fi xed value or a predefi ned
profi le can be followed, regardless of pressure variations or other changes
in the system. Type 8710 can optionally be calibrated for two different
gases, the user is able to switch between these two gases
