Gas Flow meter and its Benefits


A gas flow meter is a piece of essential equipment needed in almost every industry. They help in regulating and monitoring the flow of gases and liquids through pipelines.

While working in industries like food processing plants, chemical factories, paint manufacturing factories, petroleum refinery, natural gas plants etc. it is necessary to control the flow rate of gases. These industries operate with several harmful gases. Any direct contact of these gases or liquids to the human body can cause serious consequences.

These harmful liquids or gases flow through the pipeline at a different flow rate and temperatures. Any minor mistake in their flowing operation can cause pipeline failure. It can cause disastrous consequences to both the industry and its workers.

To overcome it a revolutionary device known as Gas Flow Meter is used. A Gas flow meter eliminates any possibility of pipeline failure. It indicates the accurate flow rate and temperature of the liquids flowing through the pipeline. So that if any error occurs precautionary measures like slowing down of flow rate, switching off the power supply, increasing or decreasing of temperature, etc. can be initiated.

Insertion gas flow meter or thermal mass flow meter are used to measure the flow rate of gases and liquids in large pipelines.

With dual sensors in it i.e. flow sensor and temperature sensor it is used to measure both flow rate and temperature at the same time.

An Insertion Gas Flow Meter is used in a wide range of industries to measure the flow of liquids and gases with high accuracy. It measures the amount of liquid and gas flowing through a pipeline and determines the velocity and temperature of it.

Working Principle of an Insertion thermal Mass Gas flow meter:

The principle of Heat transfer is used by an Insertion thermal Mass Gas flow meter to measure the flowrate accurately and precisely. As we have discussed that it consists of two sensors. One of the sensors is heated and act as a flow sensor while the second one is kept at a constant temperature to act as a base or reference point.

When a liquid or gas flows through a pipeline and comes in contact with the heating sensor it takes away the heat is then transferred to it which in turn reduces the temperature of the heat sensor. Here Principle of heat is applicable i.e. “Heat tends to flow from a body at a higher temperature to a body at lower temperature”. During this process, a temperature difference is created between the reference sensor and a heat sensor. The temperate of the heat sensor that is reduced is then restored by the flow meter. The mass flow signal is given by the electrical power that is used to maintain the heat of the flow sensor.

rather than calculating the volume of gas a Thermal dispersion flow meter measures the mass. The main principle that a thermal mass gas flow meter use is convection.

Because it measures the flow rate by measuring the temperature change when gas flows through the heated sensor.

Benefits of Using an Insertion thermal Mass Gas flow meter:

An Insertion thermal Mass Gas flow meter comes with several features and benefits which make it perfectly suitable for industrial use. Here is a list of some of the benefits of using an Insertion thermal Mass Gas flow meter. You can read more of their benefits here https://www.silverinstruments.com/

They have no moving parts. That means there is a minimal or low risk of damage or wear and tear. This feature allows the application of Insertion thermal Mass Gas flow meter in a wide range of industries including measuring the flow of saturated gases.
Unobstructed flow path
They are cost-effective as they do not need any pressure or temperature alterations and do not need any other equipment to install with it.
They are easy to install and suitable for both large and small pipes.
Even in varying flow rates, they have a high level of accuracy.
Since an Insertion thermal mass gas flow meter instead of measuring volumetric flow, it measures mass flow which makes it more reliable and gives a wide range of applications. Because The mass flow cannot be affected by different chemical and physical properties like density, pressure, or viscosity i.e. it remains constant.
