Flame Detection in Wastewater Treatments Plants
Help prevent devastating consequences with Rosemount™ Flame Detectors
Fast & Accurate Flame Detection
Wastewater treatment plants use and produce highly toxic and combustible gases like hydrogen sulfide gas, methane gas, ammonia, ozone and chlorine, throughout the treatment process. In the event a combustible gas like methane or ammonia ignites, it's critical to have flame detectors in place to immediately detect flames before they cause more damage. Rosemount™ 975 Flame Detectors can quickly detect fires at long distances with a high immunity to false alarms.

The Rosemount 975MR Multi-Spectrum Infrared Flame Detector accurately analyzes the multi-spectral signals of hydrocarbon gas or liquid fires by utilizing four separate IR sensors. The 975MR detects fuel and gas fires at long distances. For example, this product will detect a 1 ft2 (0.1m2) gasoline pan fire at 300 ft (90 m). The 975MR also provides a high immunity to false alarms and enhanced overall coverage range.
- Maximum flame detection range of up to 300 ft (90m)
- Six sensitivity levels, adapting to any application
- High speed response time under 50 msec (Exp./1 sec)
