Best for: Projects where pulse data is not needed and a straightforward readout is acceptable. Caution: It lacks pulse output, which may be a limitation for some data-logging setups.
GASFLEX Gas Meter G4 Submeter
Best for compact installations where space is limited. The G4 submeter is designed to meter natural gas or LPG with a compact footprint. While data on pulse output isn’t specified in the provided details, its compact design makes it a practical choice for tight utility spaces or retrofit projects where a small form factor matters.
- Compact dimensions: 8.2″ x 4.7″ x 6.6″
- Gas compatibility: Natural gas and LPG
- Integration-friendly design for tight spaces
Best for: Installers needing a small, space-efficient meter. Caution: Confirm pulse output capability if you require raw pulse data for analytics.
Buying Guide
What should you consider when choosing a pulse output gas meter?
Identify your gas type, installation location, and data needs. Pulse output is ideal for digital data logging and automation, while a clear cubic feet readout helps manual monitoring. Durability matters in spaces with vibrations or temperature fluctuations; aluminum housings are common for rugged use. Consider whether you need a diaphragm design for certain gas types or a model that supports wide gas compatibility.
Pulse output vs. readout clarity
Pulse output meters provide discrete signals for data loggers or control systems. If you plan to integrate with a data platform, verify the pulse specifications and whether you’ll need an interface or conversion. If you only need ongoing usage tracking, a clear cubic feet readout can be sufficient without external logging.
Durability and material choices
Aluminum housings (often ADC12) offer corrosion resistance and strength. PF resin valve components contribute to longevity. For harsh environments, check diaphragm durability and manufacturing quality, especially if the meter will see frequent cycling or temperature swings.
Installation considerations
Confirm pipe size (3/4″ NPT is common), available space, and panel or wall mounting needs. Ensure the meter is compatible with your gas type and system pressure. Note whether the meter is designed for residential or light commercial use, and if pulse output connections require specific wiring or data logger compatibility.
What about price and service?
Prices vary by features and build quality. Look for units with clear installation manuals, reliable diaphragms, and confirmed compatibility with your gas type. Warranty and after-sales support can influence long-term reliability in a monitoring role.

FAQ
- What is a pulse output gas meter used for?
Answer: It generates electrical pulses corresponding to gas flow, which can be counted by data loggers or control systems for precise consumption tracking. - Can these meters monitor propane vapor as well as natural gas?
Answer: Many models support natural gas and gaseous propane, as well as air and other non-corrosive gases; always verify gas compatibility in the product specs. - Is a diaphragm meter suitable for all gas types?
Answer: Diaphragm meters are common for non-corrosive gases; however, confirm the material and sealing are appropriate for your gas mixture and pressure. - Should I choose a meter with a 3/4″ NPT connection?
Answer: 3/4″ NPT is a standard size for many residential and light commercial hookups; ensure your piping matches or plan adapters. - What affects the reliability of pulse output meters?
Answer: Diaphragm durability, valve materials, connection integrity, and proper installation influence long-term pulse accuracy and data integrity. - Are these meters suitable for whole-house replacement?
Answer: Submeters are designed to monitor branches or zones rather than replace a main utility meter; they are best for monitoring consumption in specific areas.
