Environmental Measurement Research Corporation's
Gas Flow Monitoring System

The EMRC Gas Flow Monitoring System utilizes differential pressure technology. It is capable of accurately measuring gas flow from ~5 - 900 ft/sec and temperatures up to ~3,000° F. All EMRC Gas Flow Monitors are custom-designed to match each gas flow stream condition.

The EMRC Gas Flow Monitor includes an in situ flow sensor utilizing a variety of designs and materials (appropriate metallurgy/ceramic, etc.) to fit a large variety of flow measurement applications. Other subsystems including pressure signal conditioning interface, differential pressure transducer and temperature measurement subsystem (Type K thermocouple or RTD) and a primary reference and pressure auto-calibration subsystem (also available for the Type K thermocouple transmitter). The EMRC instrument package is located off-stack allowing for ease of maintenance and control. Off-stack instrumentation is packaged routinely in indoor and/or outdoor cabinetry, although it is preferable to locate instrumentation in a thermally controlled instrument/control room for ease of maintenance and enhanced performance.

The most advantageous aspect of the EMRC design is its simplicity of installation and maintenance. The resultant advantages are:

• +99.99% uptime
• Low installation cost
• Low maintenance cost
• No utilities at the stack or duct (probe can operate in explosion hazard situations)
• Fully automated calibration and purge
• Onboard primary reference manual calibration capability (no need to go back to the factory)
• In situ sensors are designed to meet extremely hostile conditions (corrosion, erosion high temperatures and moisture, etc.)
