TUBULAR LEVEL INDICATOR
PRINCIPAL OF OPERATION:-
Tubular Level Gauge for visual liquid level observation is very common in process industry. It is a simple and reliable device for direct reading in atmospheric or pressurized tank applications. It is mounted parallel, along the side of tank. As the process level fluctuates, the level in the transparent glass tube changes accordingly and gives local liquid indication. This is a very simple instrument. It is flange mounted to the tank.
As the liquid level rises in the tank, the liquid also rises inside the glass tube and one can see the liquid level in the tank. In this model the glass tube is enclosed in an enclosure which also carries a graduated scale. The liquid level in the gauge can be conveniently read against this scale.
