Anytime there is a process tank, there is a need to know how full it may be. There are numerous methods and technologies that can be applied, with varying levels of complexity and accuracy, to provide a measure and indication of tank liquid level.

A direct reading tank level gauge is essentially an extension of the tank that provides a visible indication of liquid level. The level is not inferred from a pressure reading or tank weight, nor is it represented by the movement of a float or other device. The actual process liquid can be seen by an operator or technician by looking at the clear display area of the gauge.

A direct reading level gauge connects to tank fittings at significantly high and low points along the tank side wall. The connections permit process liquid to flow into the gauge, with the level in the gauge being the same as that in the tank. A scale on the gauge provides a reference point for liquid level that can be recorded or used in other ways in the process. The simple device has no moving parts, requires no calibration, demands little to no maintenance. It can be the primary level indicating device for a manually operated fill, or act as a backup or local indicator for an automated process.

There are pressure limitations for these indicators. Higher pressure applications, or those with liquids that may foul the clear viewing area of the indicator are better handled with a magnetic level indicator. Like all instruments, proper application is the key to getting the best performance.
