Norgas Controls stocks a large variety of gas meters for almost any application whether it’s a small appliance or a pipeline application. We offer three different types of gas meters for measurement requirements: Diaphragm gas meters, Rotary meters including the Romet rotary meter and turbine flow meters. All of them will have excellent accuracy, if sized for the application correctly.
Diaphragm gas meters are the smaller of the three. They are typically installed on homes using a class 250 (250 CFH) by the gas utility and have the best turndown from maximum capacity to pilot loads. Commercial and light industrial sizes from class 400 to 1000 (400 CFH to 1000 CFH) are available for higher capacities. These rated capacities are based on an operating pressure of a 1/4 PSI (7”wc). As you increase the operating pressure, you will get much more capacity.
Rotary meters are for medium to high capacities. They are typically installed on large scale commercial and industrial applications. They have excellent turndown and have a capacity range of 600 CFH to 56000 CFH. These rated capacities are based on an operating pressure of a 1/4 PSI (7”wc). As you increase the operating pressure, you will get much more capacity.
Turbine flow meters are for medium to high capacities as well but have larger pressure drops than diaphragm or rotary meters. The capacity range is 900 CFH to 14000 CFH also at an operating pressure of 1/4 PSI (7”wc). The version we stock is strictly for use indoors and considered a sub-meter, not for billing purposes.
The basic questions to ask for selecting a gas meter are the following;
- Operating pressure (minimum-maximum)
- Capacity required (BTU, CFH, MBH, m3, etc)
- Type of gas (natural, propane, etc.)
With the above information we can select any type of gas meter for your application.
Many options can be added to various meters including pulse outputs, volume correctors as well as Measurement Canada sealing. Contact Norgas Controls to help you select the right meter for your application.
