Interface (Level) Detection: Oil / Water, Separator (Treater) Tank
Kayden CLASSIC 800 Series Thermal Dispersion Flow, Level, Interface & Temperature Switch & Transmitter
Oil is pumped from the well (or well storage) into the (“knock-out”) tank to separate the oil from the water and debris (sand, etc.). The interface (level) switch controls the (water) drain valve by energizing / de-energizing one of the internal relay contacts as the switch reacts to the material difference of the oil / water.
In oil / water interface applications the level switch must:
The Kayden CLASSIC 800 Series Thermal Dispersion Flow, Level, Interface Switch is used to provide the critical control for interface level in the tank.
Unlike float, paddle or gap switches Kayden switches feature all-welded sensors, no-moving-parts design and true digital electronics in a rugged package that is not bothered by coating of the probe and will not drift, seize or ever require calibration.
