Our range of Purge Level Indicator is used for remote indication in storage tanks, process vessels, reactors, settlers, evaporators, re-boilers and filters. With it, the tanks can be opened, pressurized or even evacuated at any altitude & at a distance around a radius of 200 feet. This is heavily used for consistent indication of the level of corrosive and hazardous chemicals. Centralized indication of level of various storage tanks is made feasible, which will help in economic and precise handling of liquids in tanks during transfer, mixing and dispatch and also help in inventory control.

The working of this system is briefed below:

  • Inert gas is purged into the system at a small negligible rate ( approx 5-10 LPM) through a drop pipe fitted in the tank or vessel
  • Back pressure created by the level of liquid is transmitted to the panel mounted or wall mounted single limb manometer remote indicator
  • This indicator can be directly calibrated in terms of level of liquid, length units, volume units or weight units
  • An equalizing line is provided for pressurization or evacuation
  • The tank pressure and the manometer pressure are equalized
  • The system consists of the following:
  • Level Indicator ( Dial Type or Manometer Type )
  • Purge rate Indicator ( Rotameter or Bubbler ) ( SS/AL ) ( G.M. / S.S. )
  • Drop pipe (C.S. / S.S. / P.V.C. / P.P.)
  • Constant differential pressure & flow controller ( AL )
  • Air filter regulator (AL) with drain cock and output gauge
