Meridian

Designed with safety and reliability in mind, the Meridian Universal Gas Detector is suitable for use in SIL-2 and SIL-3-rated systems under the IEC 61508 standards, certified by TUV-Rheinland, an independent third-party agency. Third party SIL certification validates that the product meets the most rigorous standards for reliability and performance and confirms its ability to reduce your potential for downtime and increase your safety factor. The term ‘universal’ is frequently used in the industry to characterise gas detectors that address both toxic and combustible gases, but it is rare to find instruments that truly live up to that claim. Upon close inspection, you will find that often the only characteristic that can be called “universal” is their user interface. In other words, the instrument provides a common user interface for both combustible and toxic gas detection.

The Meridian Universal Gas Detector is the industry’s first truly universal gas detection platform. Whether you need an infrared or catalytic bead sensor to detect combustible gases or an electrochemical sensor for a toxic environment, the Meridian universal gas detector utilises a single detector head to easily accept all sensor types. There is no requirement for distinct personality boards in the gas detector or different detector heads to make the instrument behave as a combustible or toxic gas detector. The Meridian gas detector accepts all sensor types in one detector. Simply attach the specific toxic or combustible sensor to the universal detector head and the Meridian gas detector will automatically determine the type of gas to be detected. Installation of the sensor is a simple plug-and-play action. At Teledyne Gas & Flame Detection, we are always looking to anticipate your future needs. We designed the Meridian gas detection platform to be future proof, allowing you to take advantage of new sensing technologies from Teledyne Gas & Flame Detection while maintaining ease of use and peace of mind.

The Meridian gas detector has a single set of accessories for your application needs—another merit of a truly universal gas detection platform. Because all accessories for the Meridian gas detector are designed for the universal detector head, there is no need for purchasing separate accessories for toxic and combustible applications. Designed with safety and reliability in mind, the Meridian universal gas detector is suitable for use in SIL-2 and SIL-3-rated systems under the IEC 61508 standards, certified by TUV-Rheinland, an independent third-party agency. Third party SIL certification validates that the product meets the most rigorous standards for reliability and performance and confirms its ability to reduce your potential for downtime and increase your safety factor.

The Meridian gas detector is certified using the highest international standards for global use and is designed to deliver additional value to our customers and reduce their overall cost of ownership. The Meridian gas detector’s intrinsically safe, plug-and-play sensor design allows you to perform sensor replacements without powering down the instrument. You no longer need to declassify an area during sensor replacement. This allows you to maintain your plant production uptime and maintain a safe working environment for workers at the same time.

Sensor calibration, while absolutely necessary, can be a very challenging and time- consuming activity. To help our customers reduce operational hazard and maintenance cost, we have designed a toxic sensor technology that is linear throughout and range agnostic. With the Meridian gas detector, you can calibrate a toxic sensor to a particular gas level and then make adjustment to the range later without having to re-calibrate the sensor to the new range. For example, to optimize maintenance workload, you can calibrate sensors in a batch in the lab and set them to a default range. Upon installation, the range on the sensors can be adjusted to the requirements of the specific location. The range on the sensor can be readjusted anytime to the set of pre-defined ranges by the end user. This sensor design also provides flexibility in easily calibrating sensors where a specific gas range is inaccessible or unavailable. Simply calibrate the sensor with an available surrogate gas range and then readjust the sensor range to the set of predefined ranges available for that sensor.

To minimize installation and commissioning time, the Meridian automatically detects current voltage and makes the required voltage adjustments for catalytic bead sensors without intervention from the installer. This reduces installation time and also the required tooling expertise necessary for sensor installation.
