With the acquisition of Environmental Measurement Research Corporation (EMRC) Bison Engineering has added instrument design, construction, and implementation expertise to our capabilities for serving industrial clients. EMRC has been providing air flow measurement instrumentation services since the 1970’s and has developed flue gas instrument application knowledge that is unmatched in the continuous emission monitor (CEM) industry. For regulatory compliance or process control, the EMRC Gas Flow Monitor offers clients a clear advantage, especially in high-temperature environments.

EMRC monitors deliver reliable, consistent results because they are designed for each application. Here are a few benefits our customers realize using an EMRC monitor:

  • Uptime typically exceeds 99.99%.
  • The system can operate in explosion hazard situations because no utilities are required at the stack or duct.
  • Calibration and purging are fully automated.
  • There is no need to send the monitor back to the factory for periodic calibration. The design includes an onboard primary reference method for manual calibration.
  • In situ sensors can be designed to operate in gas streams with extreme characteristics such as high corrosivity, temperature, moisture content, and particulate loading.
  • Because the monitor is based on relatively basic physical principles, installation and maintenance costs are low.
  • Application-specific monitor and installation design deliver flexibility and long-lasting accuracy.
  • Very hostile in situ conditions can be monitored without endangering expensive instruments

EMRC monitors meet industry demands requiring simplicity and regulatory compatibility. For example:
The in situ sensor is a stack or duct-mounted heavy duty S-type pitot, manufactured to withstand corrosion, high temperatures, and other hostile conditions. Plugging is avoided via backpurging, as necessary. Advantages include:

  • Sensor replacement cost is minimal
  • Methodology is EPA method #2
  • Only the sensor is mounted on the stack/duct, minimizing maintenance

All instrument equipment is located at convenient locations. Advantages include:

  • Minimal maintenance, conducted under ideal conditions
  • Monitor can be centrally located with other monitoring equipment (off stack)
  • Simplified operation and daily calibration

Monitors are calibrated dynamically (auto-cal and manual primary reference). Advantages include:

  • Signal output is easily verified against EPA #2 standards via onboard manometer
  • Dynamic (pressure) auto-calibration is included

EMRC gas flow monitors combine innovation with ultra-reliable, proven technology. Today’s models can easily be integrated into a bank of existing gas analyzers, and the front panel configuration reduces the need for additional test equipment. It’s easy to set up, and should process variables change, it’s easy to rearrange. EMC monitors – each custom designed for your application – employ leading edge technology that ensures compatibility with future advances in the industry.
