Detecting Natural Gas and Hydrogen in One Instrument


Teledyne Gas & Flame Detection is releasing an enhanced version of the popular Gasurveyor 700 (GS700), known as the GS700-Hydrogen. This upgraded model incorporates the capability to detect hydrogen (H2


), in addition to its existing ability to detect natural gas (NG). This integration of natural gas and H2 detection within a single instrument enhances versatility and performance across various gas utility applications. Notably,


extensive testing and collaboration with major UK gas utility companies played a crucial role in the development of this new instrument. Whether it’s natural gas, pure hydrogen (100% H2


), or hydrogen blends, the portable GS700-Hydrogen simplifies gas detection across applications


like outdoor and indoor leak detection, purging, barholing and pipeline gas testing. Providing safety and peace of mind, the fully ATEX-certified instrument enables utilities to quickly determine the source of gas leaks.


The development of the lightweight (1.4kg) yet durable GS700-Hydrogen was supported by comprehensive field trials aligned with the hydrogen transition efforts of prominent UK utility companies: SGN and Northern Gas Networks.


In Scotland, SGN’s H100 Fife project will establish the world’s first green hydrogen gas network in Levenmouth, Fife. This pipeline, entirely dedicated to 100% hydrogen, will run parallel to the existing natural gas distribution pipeline, providing customers with a choice between the two gases. SGN collaborated with Teledyne Gas Measurement Instruments, a Teledyne GFD brand, to develop the GS700-Hydrogen. This collaborative process ensured the instrument’s suitability for emergency response and engineering teams, enabling them to precisely detect and locate both H2


and natural gas leaks. The collaboration resulted in refining the instrument’s operation and validating its technology.


Teledyne GMI subsequently partnered with Northern Gas Networks as part of the UK’s ‘H21’ hydrogen homes project. Northern Gas Networks adopted the GS700-Hydrogen to ensure safety within their H21 networks and measure hydrogen during activities like purging and pipeline commissioning.


The successful outcome of this collaborative development approach, under real-world operating conditions, led to the inclusion of many added-value features. These include user-friendly display options that provide


comprehensive gas readings at users’ fingertips. The instrument displays LEL, PPM and volume gas readings, with 360° alarms ensuring operator safety. Users can effortlessly view either the total flammable reading or the individual LEL readings (natural gas or hydrogen) at the touch of a button. The user interface is fully configurable, allowing customisation to the specific requirements and preferences of gas utilities.


Dedicated application modes, such as gas leak outdoors, purging, barholing and search operations, offer inherent flexibility. Each mode delivers fast and accurate measurements, aiding in swiftly pinpointing gas leaks and ensuring utilities are best equipped to protect people and safeguard property. Additionally, the GS700 incorporates compliance features through intelligent data-logging and optional GPS mapping. These functionalities simplify data collection and empower managers to make informed decisions based on data driven reports.


With the new GS700-Hydrogen from Teledyne Gas and Flame Detection, any gas utility involved in hydrogen transitioning can now leverage the benefits of both H2


and natural gas detection using a high-performance


and highly flexible all-in-one instrument. More information online: ilmt.co/PL/Ve2y

Dedicated IR sensor ensures stable and reliable methane detection measurements


Teledyne Gas and Flame Detection is introducing a new infrared (IR) sensor for its class-leading OLCT 100 XPIR (explosion-proof IR) fixed gas detector that will bring the advantages of stable and reliable methane detection measurements to the industrial, utility and laboratory markets.


Methane poses many threats. Not only does it form potentially explosive mixtures with air, but it can also prove harmful to both humans and the environment. For these reasons, many sectors are keen to step up their methane detection capabilities. Increasing demand from the industrial, utility and laboratory markets stems from the need for enhanced measurement stability, aligning with the trend of lower alarm thresholds.


The economic advantage of investing in IR technology becomes apparent when considering factors such as total cost of ownership (TCO), especially in environments when gases such as methane are present. In such applications, IR technology outperforms catalytic oxidation, a process that typically requires recurring sensor replacements and frequent calibration.


To meet market demand fora more robust and cost-effective solution, Teledyne GFD is releasing a new IR sensor dedicated to methane detection. Designed for the company’s highly popular OLCT 100 XPIR fixed gas detector, the IR sensor ensures measurement stability and is impervious to catalytic poisons. Moreover, the solution offers a long lifespan, even with the presence of background gas, to deliver 100% LEL methane detection.


To explain the principle of operation, IR methane sensors deploy two wavelengths of IR energy: one active wavelength for gas absorption and one providing a reference wavelength to compensate for the impact of temperature and humidity. As IR sensors do not require oxygen to operate, these sensors are also suitable for use in 0-100% by volume methane gas environments.


The ATEX-approved OLCT 100 XPIR, a proven performer in the detection of refrigerant, CO2 4-20mA output ensuring safe and reliable operation.


and combustible gases, comes with


“Our new OLCT 100 XPIR with IR methane sensor ensures the protection of workers, assets and the environment from the potentially damaging and harmful effects of methane,” explains Régis Prévost, Product Line Manager atTeledyne Gas and Flame Detection. “Our expert design and development team is constantly looking at ways to meet the demands of customers, helping them overcome real market challenges. With this new product they now have access to a stable, reliable and cost-effective way of performing methane detection measurements.”


As a final point of note, the same IR sensor technology is available with Teledyne Gas and Flame Detection’s 700 series of fixed gas detectors. These advanced instruments display sensor status information on a built-in alphanumeric LED screen.
