TunnelCraft - Model 4 - Air Flow Monitor (AFM)

by Codel International Ltd     based in Bakewell, UNITED KINGDOM

The Air Flow Monitor (AFM) uses ultrasonic technology to measure air velocity. A single transmitter and an array of four receivers are contained in the measuring head. Air velocity and direction are calculated from measurements of the phase shifts from the ultrasonic signals at the receivers. The sensor is compact, contains no moving components, ...

TunnelCraft - Model 4 - CO & Visibility Air Quality Monitor (AQM)

by Codel International Ltd     based in Bakewell, UNITED KINGDOM

The TunnelCraft 4 CO/VIS Air Quality Monitor (AQM) uses infrared light and visible light to measure carbon monoxide and visibility in a single compact instrument. The AQM consists of a transceiver that projects infrared beams to a reflector unit mounted 3m away. The reflected light is received by the transceiver and the specific absorption is ...

TunnelCraft - Model III - NO2 Air Quality Monitor (AQM)

by Codel International Ltd     based in Bakewell, UNITED KINGDOM

Nitrogen dioxide (NO2) is fast becoming the most important measurement in tunnels and will eventually replace nitric oxide (NO) as the key measurement. The TunnelCraft III NO2 Air Quality Monitor (AQM) uses a high-power blue LED to measure the attenuation of UV/blue light by NO2 in the tunnel atmosphere. The AQM consists of a transceiver that ...

TunnelCraft - Model III - Visibilty Air Quality Monitor (AQM)

by Codel International Ltd     based in Bakewell, UNITED KINGDOM

The TunnelCraft III Visibility Air Quality Monitor (AQM) uses visible light channels to measure the visibility within a tunnel environment. The AQM consists of a transceiver that projects visible light to a reflector unit mounted 3m away. The reflected light is received by the transceiver and the specific absorption is measured to determine the ...

TunnelCraft - Model III - CO/NO/VIS Air Quality Monitor (AQM)

by Codel International Ltd     based in Bakewell, UNITED KINGDOM

The TunnelCraft III CO/NO/VIS Air Quality Monitor (AQM) uses both infrared light and visible light channels to measure carbon monoxide, nitric oxide and visibility in a single compact instrument. The AQM consists of a transceiver that projects infrared beams to a reflector unit mounted 3m away. The reflected light is received by the transceiver ...

Tunnel Sensors - Model VCOM - CO and Visibility Monitor for Tunnels

by Tunnel Sensors Limited     based in Brackley, UNITED KINGDOM

The VCOM tunnel monitor measures the concentration of carbon monoxide (CO) in tunnel atmospheres and makes a visible opacity measurement to determine the visibility within the tunnel. These measurements can be used as part of an air quality management system for ventilation control and/or secondary smoke detection within a traffic tunnel or other ...

Tunnel Sensors - Model NOVICOM - NO, (NOx), CO and Visibility Monitor

by Tunnel Sensors Limited     based in Brackley, UNITED KINGDOM

The NOVICOM tunnel monitor measures the concentration of nitric oxide (NO) and carbon monoxide (CO) in tunnel atmospheres and makes a visible opacity measurement to determine the visibility within the tunnel. Total oxides of nitrogen (NOx) can be inferred, or calculated, from the NO measurement so the NOVICOM can also present a NOx reading*. These ...

Tunnel Sensors - Model AIRFLOW - Air Velocity and Direction Monitor for Tunnels

by Tunnel Sensors Limited     based in Brackley, UNITED KINGDOM

The AIRFLOW tunnel monitor uses proven ultrasound technology to measure the speed and direction of air movement within the tunnel environment. These measurements can be used as part of an air quality management system for ventilation control wihtin a tunnel or other confined space including traffic tunnels, rail tunnels, cable tunnels as well as ...
