Roastove Gas Meter, Natural Gas Submeter
- Brand: Roastove
- Connection: 3/4″ thread; pulse output option
- Suitable for natural gas, gaseous propane, air, and other non-corrosive gases; durable aluminum die-cast housing
- Safety: diaphragm tested for long-term durability (3 million bends)
Best for: Homeowners needing a dedicated submeter for a specific gas line to monitor consumption. The unit’s pulse output makes it easy to integrate with monitoring software or an energy management setup. Caution: Verify compatibility with your gas line configuration and ensure proper installation to avoid leaks.
EKM Metering 3/4″ Gas Meter – Aluminum, Pulse Output
- Brand: EKM Metering
- Output: Pulse
- Reads in cubic feet with tenths resolution
- Suitable for natural gas, gaseous propane, air, and other non-corrosive gases
Best for: Readers who want a straightforward, compact meter with clear pulse output for data logging. Better for: users who value precise cubic-foot readouts and easy integration with monitoring systems. Limit: Might require compatible pulse receivers for full analytics.
Roastove 3/4″ NPT Gas Submeter
- Brand: Roastove
- Connection: Standard 3/4″ NPT
- Readout: Cubic feet
- Housing: Aluminum
Best for: Installing a robust, diaphragm-style submeter in residential gas lines. Choose this if: you require a diaphragm meter with a reliable readout and compact form. Limitation: Does not include a pulse output, which may affect automated data logging without an external sensor.
GASFLEX Gas Meter G4 Propane Natural Gas Submeter
- Brand: GASFLEX
- Compact dimensions: 8.2″ x 4.7″ x 6.6″
- Designed for LPG and natural gas submetering
Best for: Small spaces where meter footprint matters. Better for: basic metering needs with a compact form factor. Tip: Ensure the unit supports your gas type and installation kit.
Klein Tools ET120 Gas Leak Detector
- Brand: KLEIN TOOLS
- Detection range: 50–10,000 ppm (based on methane)
- Gooseneck probe for hard-to-reach areas
- Alarms: visual LEDs and audible alerts
Best for: Quick, on-site leak indication around appliances, pipelines, and vents. Choose this if you want a portable safety tool in addition to meters. Limitation: It is a detector, not a metering device, so it does not measure cumulative gas usage.
Buying Guide: Key Considerations for Residential Natural Gas Meters
- Meter type and purpose: Choose diaphragm or piston submeters for direct usage tracking, and consider a meter with pulse output if you plan to connect to a data logger or smart home system.
- Connection size and compatibility: Most residential lines use 3/4″ NPT or threaded connections. Verify that the meter’s inlet/outlet threads match your piping.
- Readout format: Readouts in cubic feet are common in U.S. homes. Some meters provide tenths of a cubic foot for finer granularity.
- Material and durability: Aluminum housings are lightweight and durable, suitable for residential environments and quicker installation.
- Safety and testing: Meters with robust diaphragm components and proven bending or endurance tests offer long-term reliability in normal household conditions.
- Pulse output and data integration: Pulse-capable meters are better for households using energy management software or IoT monitors.
- Leak detection as a complement: Having a dedicated leak detector enhances safety, especially near gas appliances, fireplaces, and basements.

Installation tips
- Consult local codes before installing any gas metering equipment. Use approved fittings and sealants compatible with natural gas.
- Have a licensed professional inspect for leaks after installation and verify airtight connections.
- When using pulse-output meters, ensure your data receiver or controller is configured to interpret the pulse signals correctly.
What to ask before buying
- Does the meter support your gas type (natural gas, propane, etc.) and pressure range?
- Is the connection size compatible with existing piping in your home?
- Do you need a pulse output for data logging or a simple readout only?
- Is there a built-in readout or will you require a separate monitoring module?
Frequently Asked Questions
- What is a residential gas meter submeter used for? It measures consumption on a specific gas supply line within a home, helping track usage and manage energy costs.
- Do all gas meters have a pulse output? No. Some meters provide a direct readout, while others offer pulse outputs for data logging or automation.
- Is a gas leak detector considered a replacement for a meter? No. A leak detector helps with safety checks, but it does not measure ongoing gas usage like a meter does.
- Can I install a gas meter myself? Gas work should be performed by a licensed professional to ensure safety and code compliance.
- What should I consider for safety with gas meters? Ensure proper venting, secure mounting, appropriate clearances, and routine checks for leaks around the meter and connected lines.
- Are aluminum housings better for residential meters? They are durable and lightweight, suitable for most home installations, but always follow manufacturer guidance for your environment.
