• 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.

788 D/P Purge Control is a differential pressure regulator and air flow control. It generates a constant flow of compressed air to purge a downpipe. Its integral differential pressure transmitter provides 4-20 mAdc output proportional to liquid level.

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

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.

• Measure Level, Volume or Ullage
• Advanced Smart Radar Improves Reliability
• Use for Potable Water, Fuel Oil, Service Tanks

KING-GAGE LevelWAV microwave level transmitter provides continuous measurement of liquids and solids. Measurement is independent of dielectric constant, temperature, pressure and density variations. It is suitable to a broad range of level mesurement applications regardless of visible vapors, foam, surface agitation, high temperature and/or pressure. Radar level measurement is a practical solution to failing or erratic tank level transmitters.

A compact mounting footprint permits tank top mounting in tight spaces. Accurate and reliable operation with no moving parts or submerged components eliminates the maintenance requirements of other level technologies. Applications include ballast monitoring, fuel oil, day tanks, greywater/blackwater, waste oil and drilling mud. LevelWAV is also available in a sanitary configuration for safeguarding potable water supplies.

2-wire technology means LevelWAV level radar is easier to implement and simplifies shipboard wiring for lower cost.  The LevelWAV transmitter is a two-wire loop powered unit intended for tank top installation. Stainless steel housing and rugged digital circuitry are well suited to the marine environment. IP68 rating safeguards reliability when exposed to extreme environments including deck mounting.

• Simple Inline Installation
• Float Check Avoids Pressure Drop
• Guards Against Siphoning From Tank

This engineered component will help you prevent siphoning or backflow of liquid through a downpipe installed in tank level gauging applications. With the KING-GAGE® Downpipe Backflow Check Valve, you can guard against liquid traveling up through the downpipe and into the system pressure lines. It utilizes a specially designed float pin that rises up to seal the valve shut when liquid enters from the downpipe through the bottom of the unit. The Model 6563 Downpipe Check Valve is well suited for use on downpipe systems employing KING-GAGE Purge Control or LiquiSeal Purge Control liquid level transmitters.
