Air Flow Monitors – Rohtang Road Tunnel

In early January 2020 CODEL received a prestigious order for the supply of 11 sets of air quality and air flow tunnel monitors for the 8.8KM Rohtang Road Tunnel in India. The Rohtang Tunnel is the world’s highest road tunnel situated under the Rohtang Pass of eastern Pir Panjal range of the Himalayas on the Leh-Manali Highway […]


Covid 19 – UPDATE 24th March 2020 In line with Government measures to reduce the spread of coronavirus, members of our office staff who can do so, are working remotely from home. This means there may be a delay on answering the phone if you call the office due to the reduced number of staff. […]

What is a Flue Gas Dew Point and How Does It Affect Sensor Choice?

Defining an emission monitoring sensor’s suitability for an application is a key step in ensuring a reliable and trouble-free operation of the device. There are a number of factors that need to be considered, for example, gas temperature, flue gas dew point, dust load, stack gas pressure, water vapor concentration, location, and hazardous area classification […]

Normalisation in Emissions Monitoring – What Does It Mean?

Emission sources (stack emissions) are found across different industries including power generation, cement production, steel making, energy from waste, chemicals processing, oil and gas refining and food processing. Emission monitoring systems that measure emissions released into the atmosphere are used to demonstrate compliance with environmental regulations. It is preferred, to report gaseous or solid emissions […]

The Requirement for SCR & SNCR

For decades coal has been the fuel of choice for most power stations around the world but also happens to be the most pollutant. The environmental regulation in Europe, China and India has stringent emission limits which coal fired power stations are finding it increasingly difficult and expensive to comply with and are therefore employing […]

Are You Using Bag Filters to Control Dust Emissions?

Power plants, cement plants, steel plants, smelters, asphalt plants, incinerators, food manufacturers, chemical producers, pharmaceutical producers, and other industrial companies are widely using bag filters to control Dust Emission. On some applications bag filters are also used to capture other product coming out of mills, for example, cement, coal, and other raw materials. Fabric filters, […]

Why Measure Flue Gas Velocity?

Many industrial processes release flue gases to the atmosphere. Under European Directives the majority of those are classed as emission sources and therefore require continuous emission monitoring. European standards for monitoring pollutants and flow for CEMS (Continuous Emission Monitoring Systems) are already in place and other countries usually follow them to some extent. The CODEL […]
