EMRC Gas Flow Monitor
for Emissions Compliance and Process Performance Monitoring

The EMRC Gas Flow Monitoring System measures gas flow in a plant stack or gas stream.
It is designed for , a corrosive environment, and a nominal particulate loading.
In addition, the techniques employed meet regulathigh temperatures (~1,500-2,000°F)ory (EPA and State) measurement criteria.
Gas Flow The gas flow system consists of an “insitu” S-type pitot located at a representative location in the stack or duct.
(Representative siting is determined by taking a gas flow profile during normal operations.)
The resultant dynamic pressure (Delta P "H20) is transmitted via open tubes to an instrument enclosure located on site or at another report location (up to ~1,000 ft.).
Each open tube is directly connected to a signal conditioning module (chemical-mechanical adsorption and damping).
After signal conditioning the gas flow signal is channeled to the signal transducer module.
The signal transducer produces a DC output which is routed to an electronic conditioner and interface.

• High Temperature Range (~1,500-2,000°F)
