This Sight Glass is designed to be welded directly onto a tank or other liquid-containing vessel. Standard Liquid Level Gauge units are furnished with a flat bottom. Upon request, the Sight Glass can be machined with a cylindrical radius to match the contour of the vessel. The Sight Glass are available in single or multiple section types.

Flapper Type Sight Flow Indicators are best suited transparent or slightly opaque solutions and are used for gases also. Position of the flapper indicates flow. One important use of these flow indicators is, in pipelines where a downstream value may remain closed and even through the flow indicator remains full, there may not be any flow. In such cases, the flapper position alone can indicate where there is flow.

Rotating wheel (Rotary) type Sight Flow Indicators are suitable for installation in any position, but are particularly adapted to pipelines carrying dark opaque solutions, where the motion of the wheel is easily detected. This model is equally adapted to transparent solutions and gases. It is frequently installed where observations must be made from a distance.

Full View Flow Glass are assembled with tubular Borosilicate glass. These indicators are simple in construction and used for checking flow from any direction where various values or pump might have to be operated based on the flow in the line. These are recommended where there is no mechanical strain in the pipeline. Inside diameter of the glass tube is as large as or larger than the nominal size of the flow indicators.
