Fire detection solutions for the power stations sector
One of the main hazards in a power station is a fire in a coal rich environment; the latter can often become an explosion with consequential damage to human life and capital equipment.
Fire detection solutions for the oil rigs areas
The worse event that can befall on off shore oil rig is fire. The Model 125 is a smoke monitor designed to operate in hazardous areas, especially in oil rig air conditioning and ventilation ducts. The electronics are contained in an explosion proof container rated as EEX de II B T5; the sensing head uses fibre optic cables to transmit the near infra-red light to a reflector where it is returned to another fibre optic cable. The light level is then monitored by a photo-electric cell. The Model 125 gives an...

Industrial monitoring solutions for the gas analysers areas
Most large coal fired power plants and combustion processes are required to monitor CO, NO and NO2 (NOx), SO2 and possibly CO2; in addition the analyser has to be normalised to Standard conditions. For this application CODEL offers the five channel GCEM 40 series which uses Infrared absorption to measure these gases plus moisture, pressure and temperature. ...
Industrial monitoring solutions for the dust monitors areas
For large combustion plants and power plants we offer the DCEM 2100 particulate monitor. This monitor is certified to EN 15267 part 3 QAL 1 for all industrial processes including waste incineration. It offers outputs in Transmission, Opacity and mg/m3 (when calibrated against a Standard Reference Method). The
Industrial monitoring solutions for the flow monitoring areas
Many large combustion plants are now required to monitor mass emissions of major pollutants and to do so requires an accurate measurement of stack gas velocity. The VCEM 5100 is certified to EN 15267 part 3 QAL 1 for all industrial processes including waste incineration. It has several key advantages, firstly the sensors optics are not in contact with the hot and dusty environment, the VCEM 5100 can monitor gases at temperatures exceeding 10000C and the analyser requires minimal maintenance. The VCEM 5100 can...
Industrial monitoring solutions for the opacity and dust monitoring areas
There is a requirement for many small boiler operators to monitor Opacity to determine the smoke density emitted from the boiler. On small boilers we recommend the DCEM 1001 Opacity monitor; this simple, low cost monitor has high efficiency air purges use compressed air to ensure that optical surfaces are virtually free of dust or debris contamination. This ensures minimal maintenance is required on the sensors.
Industrial monitoring solutions for the dust collectors areas
Most industrial processes have dust collectors of some form or other, the most popular being filter bag houses. Very few of these are covered by regulation other than to have a broken bag detector to prevent nuisance dusts escaping and creating a local nuisance. The CODEL StakGard is a low costManufacturing, Other
Monitoring solutions for the marine industry
While land-based industry has been subject to strenuous emissions regulations over the past decades, air emissions from sea-going ships’ machinery has so far been largely unregulated. As a result, according to EU statistics, ships have become the single biggest source of sulphur dioxide (SO2) within the EU. The US EPA (US Environmental Protection Agency) reports similar findings, i.e., that the proportion of air pollutants released which can be attributed to the shipping industry is increasing....
Tunnel solutions for the visibility monitor areas
The TunnelTech 101 Visibility Monitor (VIS), is an essential part of any road or rail tunnel safety system. It monitors the Visibility within the tunnel and ensures that the tunnel ventilation system provides sufficient clean air for drivers to clearly see the road ahead. The TunnelTech 102 Cold smoke monitor (CSM detects smoke from a fire to rapidly warn the operator of the hazard. Secondly, used in combination with other TunnelTech 101 VIS monitors, the operator can quickly detect the locus of the fire if it...
Tunnel solutions for the tunnel air flow
Tunnel ventilation systems are designed to enable a sufficient throughput of air to be maintained to ensure a safe operating environment for users. These systems consume large amounts of power and need to be operated as efficiently as possible. To do this it is necessary to know the effectiveness of the system in terms of air flow and direction developed within the tunnel. The TunnelTech 301 is a single point ultrasonic flow monitor that is unaffected by traffic flow and sound reflections. It is designed to...
Tunnel solutions for the extractive areas
In some countries they do not allow tunnel atmosphere monitors to be mounted on the tunnel wall; also, where there is a single bore it is very difficult to gain access for maintenance purposes. The TunnelTech 400 series are extractive gaseous pollutant and visibility monitors and extract a gas and dust sample from the tunnel bore and carry to a remote analyser. This allows maintenance to take place without affecting tunnel traffic flow.

Tunnel solutions for the light sensors
According to the International Committee on Illumination CIE recommendations, luminance should be monitored as the luminance contained within in a conical field of view, subtending an angle of 20º. It is recommended that a luminance photometer is mounted in the tunnel approach road approximately 120 - 200 metres from the portal, depending on the approach speed of the vehicles and their stopping distance. The purpose of monitoring the luminance at the portal is to adjust the level of light intensity inside...
Stack emissions monitoring
Monitoring stack emissions is a fundamental requirement for most industrial processes. Our gas analysers, dust monitors and flow monitors are designed for a wide range of applications and can operate as a fully integrated system or as stand alone instruments.
Tunnel solutions for the gaseous pollutants
The TunnelTech 200 series are primarily gas monitors with optional Visibility capability. Most use Infra-red absorption technology to monitor gaseous pollutants and those with a visibility channel use optical attenuation for that application. All TunnelTech 200 analysers except the TunnelTech 205...
Industrial monitoring solutions for the flue gas desulphurisation areas
Most large coal fired plants have a flue gas desulphurisation (FGD) plant to lower SO2 levels to below emission limit levels. The CODEL GCEM 40 series is used to monitor SO2 levels after the FGD to ensure they are below required levels and to ensure that the process is not too efficient and using too much sorbent. In addition, many plants monitor pre and post the FGD to ascertain the efficiency of the plant.
Industrial monitoring solutions for the de-NOx plants areas
In recent years the number of Selective Catalytic Reduction (SCR) and Selective Non-Catalytic Reduction (SNCR) plants for De-NOx have increased significantly. Continuous analysis of NOx prior to the de-NOx plant is often required to measure the concentration generated by the combustion process. This may be required to provide feed-forward to the Ammonia/Urea injection system and also to allow the effectiveness of the reduction process to be assessed. Continuous analysis of NOx post-reduction is required to...
