summary:
(called controller) adopted advance technology to develop for level measuring.it
is stable and steady,can control level and surface of medium which widely used
in petrol,chemistry,electricity,medicine,foodstuff,paper-making.it can accompy
with PLC or DCS.
theory:
Use
joint point to measure if air or material exsise .controller is made up of
circuit and joint point.
