Instrumentation for Natural Gas & LNG Facilities
Analytical, flow, water-quality, temperature, and materials instruments for gas treatment, liquefaction, storage, transfer, and supporting utility systems.
Measurements that support gas quality, treatment, and reliable transfer
Natural-gas processing and LNG facilities must control sulfur-bearing components, treatment performance, gas quality, flow, utilities, materials, and operating conditions across high-pressure and cryogenic process systems. The measurement solution must be matched carefully to the gas composition, pressure reduction, sample transport, installation area, and response-time objective.
Blue Dragon Technology supports gas-processing and LNG projects with total-sulfur and hydrogen-sulfide measurement, sulfur-recovery monitoring, industrial ultrasonic gas-flow instruments, water-quality analysis, elemental verification, and engineered temperature assemblies. Configuration and integration are reviewed at project level.

Explore →Industry questions.
What information is needed for a natural-gas analyzer application?
Provide the gas composition, target component, expected range, pressure, temperature, moisture, possible condensables, sample take-off location, area classification, utilities, and required response time.
Can ultrasonic flow meters be selected for different pipe arrangements?
Yes. Selection depends on pipe size, pressure, temperature, velocity range, gas composition, required accuracy, available straight run, insertion or inline preference, and installation access.
How is condensation risk handled in gas sampling?
The complete sample path must be reviewed, including pressure reduction, heat tracing, filtration, transport time, materials, and the phase behavior of the stream.
Can the same portfolio support LNG utilities and wastewater?
Yes. Water-quality and elemental instruments can support utility, treatment, maintenance, and laboratory requirements alongside the process-gas measurements.
Discuss your natural gas or LNG measurement application.
Provide the gas composition, measurement range, pressure and temperature, flow conditions, sample location, area classification, utilities, and project schedule.
