2. Rotary Gas Meters

Rotary gas meters are used in larger commercial and industrial applications where higher gas flow rates are required. They operate based on the principle of two interlocking rotors that rotate as gas passes through them. The rotation of the rotors is directly proportional to the volume of gas being consumed. Rotary gas meters are known for their accuracy and durability.

3. Turbine Gas Meters

Turbine gas meters are used in applications where high accuracy is required, such as custody transfer and billing purposes. They consist of a turbine wheel that spins as gas flows through it. The speed of the turbine wheel is directly proportional to the volume of gas being consumed. Turbine gas meters are highly accurate but can be more expensive than other types of gas meters.

4. Ultrasonic Gas Meters

Ultrasonic meters use sound waves to measure the velocity of gas flow. They are non-intrusive and do not require any moving parts, making them highly reliable and low maintenance. Ultrasonic meters are often used in applications where the gas being measured is contaminated or contains particulate matter.

How Does a Gas Meter Work?

A gas meter works by measuring the volume of gas flowing through it. The gas enters the meter through an inlet, and as it passes through the meter, it displaces a series of internal components that are designed to measure the gas volume. The displacement is then translated into a measurement of gas consumption, which is typically displayed on a dial or digital display.

Gas Meter Components

A typical gas meter consists of the following components:

a. Inlet

The inlet is the point where the gas enters the meter. It is connected to the gas supply line and allows the gas to flow into the meter for measurement.
