Types and Applications of Dual Chamber Orifice Fittings

Orifice fittings are present in an orifice meter. Hence, let’s begin with understanding what an orifice meter is. An orifice meter is equipment that measures the flow of a gas or a liquid without changing its pressure. It comprises three main parts: a meter tube, an orifice plate, and an orifice plate housing.

Orifice meters come in three different kinds of fittings, single, Dual, and Block and Bleed Chamber fittings. The article explains the applications of dual-chamber orifice fittings along with the other types of fittings. And for further information you can visit the website.

Types of Orifice Fittings

Below is the detail of different types of orifice fittings.

Single Chamber Fittings

The name of the fitting is relatively self-explanatory. This fitting only consists of a single chamber but provides precise flow measurements. Single chamber fittings are suitable for depressurization and replacement activities within an orifice meter.

Dual Chamber Fittings

The dual-chamber fittings consist of two measuring chambers. A dual-chamber orifice fitting works with upstream and downstream chambers. It includes an O-shaped steel ring which eliminates the need for a gasket. Additionally, there is a pressure controlling valve included. Dual chamber fittings offer more component control as compared to single chamber fittings.

Double Block and Bleed Fittings

DBB fittings are the most intelligent kind of fittings. They include two individual valves for operational safety. Moreover, their sturdy construction makes them more resistant to toxic materials. Double block and bleed fittings are present on large industrial projects which work with toxic chemicals and gases.

Applications of Dual Chamber Orifice Fittings

Since dual-chamber orifice fittings are most commonly available, knowing where they serve might be beneficial.

Water Purification Plants

Running water has flux, which one must measure to calculate the amount of energy produced. Dual-chamber fittings calculate the flow rate of the water moving from the disposal tank to the treatment tank. A reader measures the flow rate when the water stream passes through a dual-chamber fitting. These values further help calculate a water unit’s flux to energy value.

Hydro Power Plants

Another familiar spot to find dual-chamber fittings is in hydropower plants. As the water rushes from penstock to turbines, its speed and volume are measured using these fittings.

These values assist in setting the optimal power production settings, so the plant generates more power and works optimally. Additionally, estimated water flow values help prevent power instability, which is a significant risk in hydro plants.

Chemical Chambers

Chemicals require continuous monitoring. Therefore, the dual-chamber fittings are installed with chemical tanks to check and measure the flow of chemicals. Reactive chemicals need a controlled environment. Else, they may risk the safety of the staff.

Moreover, optimal flows are necessary for the manufacturing of various products. Without something to control and measure the flow rate of the chemicals and gases, the product may come out as desired.

Oil Plants

Dual-chamber fittings ensure an optimal flow when oil travels from discharge tanks to pipelines. Strict monitoring and optimal performance are mandatory to balance product and demand in oil and petrochemical plants.

Gas Supply Plants

Like oil plants, gas plants require reliability, efficiency, and optimality. Else, the consumption will be too great to fulfill. Dual-chamber fittings also contain a gasket that helps measure the gas’s pressure and flow rate without affecting the pressure. Transferring the proper pressure is extremely important. Else, it may not serve as an industrial power source.

Conclusion

Dual-chamber fittings work with an orifice meter. However, the efficiency of the meter depends upon the fitting installed. Dual-chamber fittings are preferable as they have pressure control valves.

As orifice meters commonly use these fittings, one must know where they are most beneficial. The above article highlights the applications of dual-chamber fittings. However, they are not the only kind. You can also employ other fittings depending on your needs.
