The sight glass is one of the equipment which can be well manufactured domestically in the country. Using experience and taking advantage of existing potentials, Minoodar can offer good services in this field.

Below we get to know more about this equipment.

Site glass is a tool that allows you to observe the movement of the fluid, its color and its transparency using the glass.

You can obtain various information using the sight glass on the performance of the system, valves, filters, refrigerants, and faulty steam traps. For example, the presence of a bubble or foam in the system indicates that one part is not functioning properly.

Depending on the industry type and the piping design, the site glass has a variety of uses. for example, in the steam lines path, it allows viewing of fluidized fluid, if any, to be evacuated.

The sight glasses are classified into different types. In fact, each manufacturer has developed a special type of sight glass based on its previous experience in the field.

In many cases, the manufacturer allows the installation of various mechanical indicators within the sight glass. Flapper, Propeller, Ball, Finger, Integral Spout are some of these mechanical indicators.

These indicators help the operator to detect colorless and very transparent fluids. The direction and intensity of the flow can also be detected using these mechanical indicators. The figure below shows a sight glass with a flapper indicator.  this flapper is diverted to the fluid direction. This type is very suitable for horizontal lines but is also used in cases of vertical lines facing upwards.

Since the flapper deviation is proportional to the fluid intensity, the most of the flapper type sight glasses have been equipped with a scaled plate to detect the fluid flow on which the operator can guess the approximate size of the fluid by moving the flapper on it.

The use of rotor or impeller on the sight glass is very common. This type of sight glasses is called rotary flow Indicator. The direction of fluid flow can also be guessed approximately in this type. This type of sight glass can be installed on horizontal and vertical lines. It should be noted that this model is not suitable for lines with low fluid flow, because the fluid does not have the power to drive the impeller.

In the ball type sight glass, the indicator is a ball that is suspended in the middle when the fluid flows. This type of indicator is used in vertical lines with fluid .moving from bottom to top
