How to choose the right gas meter?

Trying to choose the right gas meter can be an exhausting task for many as there is a myriad of gas meter models available on the market. Every model has its own merits and demerits, which makes it suitable for different purposes. However, there are some common factors among all kinds of gas meters, which should be considered while opting for a gas meter. Some of these factors that help in choosing the right gas meter are:

1. Purpose of the Gas Meter

The most important aspect of selecting an appropriate gas meter is to determine your requirements carefully and choose a meter according to its application. There are many types of gas meters, like diaphragm meters, turbine meters and rotary meters, which have various qualities to fulfil different requirements. Thus it should be decided where the meter is to be installed and what its purpose is.

  • Diaphragm meters are suitable for domestic uses such as residential buildings and condominiums. They are also installed where commercial usage is minimum, for example, coffee shops, small restaurants and food courts. Diaphragm gas meters are for light usage because their capacity for gas usage per hour is about 2.5 m3/hr – 10 m3/hr, which is low compared to the other types of meters.
  • Turbine Meters or rotary meters are able to support high gas usage of even more than 16 m3/hr. Therefore, these types of gas meters are commonly used in heavy commercial locations and the industrial sector. The built of the turbine of the rotary meter is robust and large to support heavy usage.

2. Required Capacity

Knowing the capacity of a gas meter is essential to make sure the model you are going to install will be able to fulfil your purpose. Thus, users must find out the gas consumption rate per hour in the area in which a gas meter is to be installed. The consumption rate helps in determining the maximum flowrate requirement of all of the gas devices present in the building. Thus it’s important to choose the right gas meter with appropriate capacity. Moreover, it also minimizes the chances of under-sizing the gas meter, which in turn ensures the efficiency of the gas equipment will not be affected.

3. Size of the Pipes

Often, it is vital for users to determine the pipe size that is going to be used in a gas meter installation. Consequently, the pipe size impacts the type of gas meters. For example, larger pipes are used in turbine meters while diaphragm meters make use of the smaller pipes.

If you’re in Malaysia or other countries it’s best to consult your gas regulators suppliers such as Comet Integrated to help you find out the exact technical specifications of the gas meters needed according to your area and requirements.

4. Gas Pressure

Gas pressure is an important factor when it comes to choosing the right gas meter. It varies on the usage and different types of gas meters.

  • Diaphragm gas meters are meant for low usage applications. They are able to endure the low pressure of up to 1.5 bar.
  • The turbine meter is used in heavy commercial areas and the industrial sector. It has the ability to withstand the maximum pressure of 6 bar. Thus, if the gas pressure is high in an area, users can install a turbine meter to control the high-pressure reading, or a gas regulator can be installed to normalize the pressure. Certain gas regulators suppliers in Malaysia (such as Comet Integrated) are able to devise a strategic solution to the gas-related problems in specific areas.

5. Location of Gas Meter Installation

While deciding the site at which a gas meter is to be installed, there are many factors that must be considered. Environmental conditions should be favourable where the gas meter is to be installed. Usually, locations with minimum or none electrical interference are selected to ensure the meter is able to provide maximum performance. Any government rules and regulations must be followed while choosing the location.

6. Types of Gas

Your gas supplier can guide you in this regard more accurately as the types of gas being supplied varies from area to area. Various types of gas like single gas, mixture gas, pipeline gas, fuel gas and digester gas are available on the market.

After carefully going through these factors, you should be able to decide the right gas meter that can fulfil your requirements. Keep in mind that even after selecting a gas meter that may seem perfect to you, it can still have some disadvantages because no technology is perfect and every gas meter has its own specifications.
