October 21, 2005 — Flush Mount Liquid Level Transmitter

Loop powered KING-GAGE® ES2i transmitter for hydrostatic tank gauging is designed for sanitary applications. Sensor is isolated using a unique sealed design while maintaining atmospheric reference. Non-repeatability for process control monitoring is less than 0.02% FS. No cost options include remote zero and terminal junction. Various mounting configurations available adapters for retrofit installations.

KING-GAGE ES2i transmitters are applicable to most tanks or process vessels whose contents remain at normal atmospheric pressure. The transmitter’s 4-20 mAdc output signal is compatible with PLCs or other control architecture using analog I/O. Accurate tank gauging can be achieved using KING-GAGE indicators or tank processors that convert the proportional output into a volumetric measurement of tank level.

Measuring hydrostatic head pressure created by liquid depth in the tank, they are unaffected by foam or internal obstructions such as agitators. Pressure affords consistent measurement because it is based on the total mass of the liquid, not the relative volume or displacement that varies by temperature.
