-
Suitability-tested and certified impact pressure system to measure velocity and volume flow of dry flue gas or process gas in pipes or ducts.
-
Suitability tested and certified ultrasonic measuring system to measure the velocity and the volume flow of flue gas or process gas in pipes or ducts, especially for wet and aggressive smoke emissions.
-
Measuring system for continuous evaluation of flow velocity and flow direction in tunnels. Ultrasonic sensors for tunnel ventilation control system. Reliable measurement across the tunnel profile. Two identical sensors alternately transmit and receive ultrasonic pulses. The system evaluates the transition times dependent on direction and calculates flow speed. D-FL 220T requires extremely low maintenance.
-
Compact and cost effective transmittance dust and opacity measuring device for monitoring medium to high dust concentrations in dry flue and process gas.
-
Ambient air particulate monitor to detect TSP, PM10 or PM2.5 in ambient air for use in industrial or governmental ambient air monitoring networks.
