Orifice Meter

Gas Analytical provides the kind of quality orifice meters their clients have come to rely on. The company has established a reputation for reliable service, quality components, and unmatched customer care. The primary function of Gas Analytical orifice meter is to measure the flow rate of a gas or liquid. This piece of equipment consists of three main parts: a plate housing, a meter tube, and an orifice plate.

Construction of Gas Analytical Orifice Meter

Gas Analytical orifice meters are usually made of carbon steel, making them incredibly sturdy and durable. The main components of the orifice meter include inlet and outlet sections, flow conditioner, and orifice plate. The inlet section consists of a linear segment that provides the end connection for the fluid flow.

Like the inlet section, the outlet section is a linear segment that generates a pressure drop to allow for accurate measurement of the flow rate. The primary function of the flow conditioner is to improve linear flow in the inlet section. It is usually installed at the inlet section of the orifice meter.

How an Orifice Meter Works

Gas Analytical orifice meter is designed to work on the principle of differentiated pressure measurement. Once a liquid is passed through the orifice plate, it creates a drop in pressure across the orifice plate. The pressure drop varies depending on the flow rate. The difference in pressure between the inlet and outlet sections allows for accurate measurement of the flow rate of the liquid or gas.

Gas Analytical provides three main types of orifice nozzle and venturi flow rate meters:

  • Single chamber
  • Dual-chamber
  • Double block and bleed

As the name suggests, the single-chamber orifice fitting features one chamber that allows for precise measurement of the flow rate of liquids and gases.

The dual-chamber setting consists of downstream and upstream sections as well as O-ring seals. This set up does not require maintenance of the gasket thanks to the O-rings. The dual-chamber setting also features a valve seal.

The double block and bleed setting feature two valves for the two chambers. The main benefits of the double block and bleed setting include:

  • Enhances operational safety
  • Protects users from toxic liquids
  • Highly durable

Applications

You can use Gas Analytical orifice meters to measure the flow rate of liquids in:

  • A single state
  • A mixed state

Liquids in a single state are in either a gaseous state or a liquid state. On the other hand, liquids in a mixed state are in both gaseous and liquid states. Liquids in the mixed state include wet steam or natural gas containing water.

Industries

Gas Analytical supplies and installs orifice plate flow meter in many industries, including:

  • Refineries
  • Water treatment facilities
  • Petrochemical plants
  • Natural gas facilities

Some of the benefits of a Gas Analytical orifice plate include:

  • It is affordable and user-friendly.
  • It takes up little space, making it ideal for space-constrained operations.
  • It is easy to install in both horizontal and vertical positions.
  • It helps to determine flow rates even in large pipes.
