In the operation of an industrial process, there may be instances where a visual confirmation or assessment of fluid flow is useful or necessary. In those cases, a direct reading sight flow indicator is just the thing needed to fill the requirement.

The sight flow indicator is essentially a clear tube with an encasement and appropriate connections that facilitate the indicator's installation into a process piping system. It is installed in a manner that provides an operator visual access to the inside of the piping at that location. Further details about construction materials, armoring, and more will round out the product selection that best accommodates the industrial environment, the media, and the visual inspection needs.

Jogler manufactures a range of flow, level and analytical instruments for industrial use. Their sight flow indicators, with line sizes from 1/2 to 4 inches and lengths up to 60 inches, enable a process operator to get that all important look at the liquid media as is passes through the flow indicator. The presence, color and character of the media can be assessed visually through the flow indicator, delivering visual confirmation of some targeted aspect of the process.

Direct Reading Level Indicator Gauge for Process Tanks

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.
