Description

2M175ITPWS Roots Gas Meter

The 2M175ITPWS Roots Gas Meter is a temperature-compensated, utility-grade rotary gas meter designed for accurate gas measurement across varying environmental conditions. Built on the proven Dresser ROOTS B3 platform, this meter delivers consistent performance, low pressure drop, and reliable pulse output for remote monitoring and control applications.

Ideal for commercial and industrial gas systems, the 2M175ITPWS combines temperature correction (TC) with a low frequency pulse transmitter (TPWS), making it a strong choice for custody transfer, sub-metering, and SCADA integration.

Temperature Compensated Pulse Output (ITPWS)

The ITPWS configuration integrates a mechanical temperature compensator with a solid-state pulse output. This allows the meter to automatically correct gas volume to standard conditions while transmitting pulse signals for remote totalization.

• Mechanical temperature compensation (TC)
• Low frequency pulse output (TPWS)
• Compatible with PLCs, flow computers, and remote displays
• Eliminates need for external volume correction in many applications

Designed for Real-World Gas Applications

The 2M175ITPWS is built for demanding environments where flow conditions and temperature fluctuate. As a positive displacement rotary meter, it measures actual gas volume independent of pressure and temperature changes, ensuring reliable performance over time.

• No straight pipe requirements
• Extremely low pressure drop (ideal for low-pressure systems)
• Suitable for natural gas, propane vapor, and other clean dry gases
• Works in both indoor and outdoor installations

Why Choose the 2M175ITPWS?

Accurate Measurement with Temperature Correction

Unlike non-compensated meters, the ITPWS automatically corrects for temperature variations, providing standardized volume output without external correction devices.

Built for Industrial Reliability

With a rugged cast body and proven ROOTS rotary design, this meter is built to operate continuously at full capacity with minimal maintenance.

Ready for Remote Monitoring

The integrated pulse output makes it easy to connect to SCADA systems, data loggers, or digital displays for real-time tracking.

Easy Installation & Serviceability

All 2M175 series meters feature a compact footprint with 2-inch flanged connections for quick installation and removal.

• Drop-in replacement for standard 2M175 configurations
• Compatible with existing meter sets and piping layouts
• Recommended: install a strainer upstream to protect internals
