King-Gage's D/P Purge Controls

King-Gage D/P purge controls send a regulated, low-volume air flow to purge a length of pipe extending downward to the tank bottom. Changes in liquid depth increase or decrease the resulting internal air pressure while a differential pressure transmitter generates a 4-20 mA output proportional to the level in the tank. Accurate level measurement and repeatability to within ±0.2%.
