In a response to South Africa's urgent need to manage the environment and prevent air pollution, Dupleix Liquid Meters (DLM) is offering the Solartron Mobrey OM80 obscuration monitor. The OM80 obscuration monitor provides continuous monitoring of smoke emission from combustion or dust emission from air filtration systems.
Diagram shows typical OM80 set-up
A beam of light is projected across the stack or duct onto the photocell in the receiver unit. Dust or smoke passing through the light beam is displayed digitally as percentage obscuration. The OM80 software is programmed for either dust or combustion monitoring. Dust alarm point values are preset at 5% and 10% with a 30 second delay. Combustion alarm point values are preset at 20% and 25% with a 5 second delay.
The dust and combustion programs are internally switch selectable by the user. The alarm set points may be re-programmed to suit a wide variety of applications. Response is immediate and unaffected by weather conditions, daylight or darkness. It is a positive aid to efficient combustion and environmental pollution control.
Features include:
* Electronic compensation for both lamp ageing and lens contamination.
* Self-calibrating zero and span.
* Full password security access.
* Digital indication of % obscuration.
* Analog and relay outputs for ancillary instrumentation and alarms.
* Switch selectable configuration for dust and combustion duties.
* Stack optics require only low voltage cables.
* Interchangeability with Electricon units.
In addition to a comprehensive product offering, DLM offers a full service backup including engineering design, supply, installation, commissioning, calibration and ongoing servicing of Solartron Mobrey products.
The importance of environmental monitoring and visibility at data centres Legrand
Analytical Instrumentation & Environmental Monitoring
Data centres are one of the most energy-intensive building types, consuming up to 50 times the energy per floor space compared to a typical commercial office building. With organisations embracing advanced technologies, data centres powering these technologies are under increasing pressure around the globe to increase capacities and improve efficiencies.

At its peak in 1994, the energy generation capacity of the UK’s nuclear power stations was 12,7 GW across 16 plants. In 2024, the capacity has fallen to around 5 GW, and the number of stations is down to nine. However, this is far from the end of the story as spent nuclear fuel remains radioactive for centuries, and requires rigorous safety processes to safeguard against leaks.
