Details for LiquiSeal Purge Control

PropertyValue
Name:LiquiSeal Purge Control
Description:

dp738

• Continuous Level Measurement
• Simple Proven Sensing Technique
• Suitable for Corrosive or Aggressive Liquids

When purged with compressed air, liquid within the downpipe is displaced by air pressure equal to the hydrostatic force of liquid in the tank. If carefully regulated at a low rate of flow, air pressure will constantly maintain equilibrium against the force of the liquid. Output is proportional to liquid depth and can be transmitted as an electronic 4-20 mA signal or pneumatically as a direct 1:1 pressure signal.

LiquiSeal D/P purge control is a fully integrated air purge regulator and level transmitter. Operation is based on the control regulating a continuous 1 cfh (cubic foot per hour) flow of compressed air into the tank downpipe. An internal differential pressure sensor element converts resulting pressure into a 4-20 mAdc two wire signal.

APPLICATION NOTE: Available in all-pneumatic configurations for hazardous area service.
