Branch Manifold
Identify dilution and decline instantly. We help you balance the network despite the unpredictable moisture, flow, and blockage behaviours unique to each branch.
Proven Industry Application
Secure Your Coal-Mine Gas Drainage Network
Unreliable methane readings in a gas-drainage network don't just cause downtime—they create unacceptable safety risks. Our TDLAS modules deliver the instantaneous, drift-free data you need at every critical node, from the branch manifold to the utilisation inlet, ensuring total process control and compliance.
Network-Wide Visibility
Solve the Unique Challenges of Every Measurement Point
A one-size-fits-all sensor will fail in a complex drainage network. We engineer our modules to overcome the specific pressure, moisture, and flow dynamics present at each critical node in your system.
Underground Main
Monitor the mixed gas before it exits the working area. Our modules are designed to survive the harsh washdown environments and strict hazardous-area constraints of underground mains.
Pump-Station Collector
When the reading triggers a shutdown, accuracy is non-negotiable. We engineer for the severe pressure transients at the collector to ensure your safety interlocks never fail.
Utilisation Inlet
Protect your downstream assets. Whether feeding an engine, boiler, or flare, our modules provide the precision data needed to meet strict acceptance and protection rules.
The Clear Choice
Why Direct Insertion is the Only Logical Solution
Extractive sampling systems in coal mines are a maintenance nightmare. Pumps fail, filters clog with coal dust, and long sample lines introduce dangerous delays. Our Pipeline Insertion TDLAS Module bypasses all of this. It measures directly in the flow via a G1 inch fitting, giving you instantaneous, reliable CH₄ data across a 0–100 %vol range while virtually eliminating maintenance costs.
We work with you to verify installation suitability, ensuring representative flow, accessible maintenance, and a clearly defined host-system boundary. Our goal is to maximise measurement reliability and minimise your total cost of ownership.

Don't Guess. Validate Your Process Conditions.
| Topic | Record | Why it changes the decision |
|---|---|---|
| Gas composition | Normal CH₄ band, extremes, water, dust and relevant background gases | Changes optical selection, contamination risk and verification plan |
| Pressure | Minimum, normal and maximum absolute pressure; transient behaviour | Changes spectral shape, compensation and mechanical boundary |
| Pipeline | Diameter, fitting, wall, orientation, local velocity profile and isolation method | Determines insertion geometry, representativeness and maintenance |
| Decision | Display, trend, warning, control or shutdown threshold | Determines uncertainty treatment and system validation |
| Host system | Power, protocol, enclosure, approval, alarm logic and document owner | Prevents a module claim from being mistaken for system compliance |
Market-specific threshold rules are not universal. For example, German gas-extraction guidance contains concentration thresholds for particular positions and actions. Those values must be labelled Germany-specific and must not be copied into another jurisdiction without checking the applicable mine rules and approved system design.
