GE ILP-1 belongs to GE professional insertion ultrasonic probe product line specially optimized for flare gas and low-flow process gas working conditions. ILP stands for Insertion Low Power, and the digit 1 represents the standard single-channel emission-receiving integrated structure. It cooperates with GF868 flare gas mass flow transmitters to capture upstream and downstream ultrasonic time difference signals, providing raw waveform data for the host to calculate gas velocity, volumetric flow and mass flow values.

The internal piezoelectric chip adopts low-power excitation design, which greatly reduces the overall power load of the measuring system under long-term uninterrupted operation, matching the intrinsic safety power supply standard of explosion-proof areas. The acoustic structure is optimized for low-speed turbulent gas flow commonly seen in flare headers; it effectively suppresses signal scattering and waveform distortion caused by gas vortex, flue dust and steam entrainment inside pipelines, solving the problem of unstable measurement data under small flow leakage and low-load blow-off working conditions of flare systems.

The wetted probe body is made of 316 stainless steel with high temperature and corrosion resistance, resisting erosion from hydrocarbon gas, hydrogen sulfide and acidic flue gas in petrochemical flare pipelines. The front sintered metal filter intercepts particulate impurities and oil mist in the gas flow to prevent pollution and abrasion of the piezoelectric wafer, extending the service cycle of the core sensing component. The overall sealed structure reaches high-level waterproof and dustproof performance, adapting to high-humidity and high-temperature outdoor flare stack installation environments.

The tail part adopts shielded aviation connector interface, compatible with GE original 710-1247 signal cables. Multi-layer braided shielding inside the wire harness isolates electromagnetic interference from field compressors, power frequency equipment and high-voltage distribution circuits, ensuring high-fidelity transmission of weak ultrasonic signals in complex industrial electromagnetic environments. The probe body supports threaded insertion installation with matched ball valve components, allowing hot plugging and maintenance without shutting down the flare pipeline system, avoiding production halt losses during probe overhaul and calibration.

It has intrinsic safety certification conforming to ATEX standards and can be deployed safely in Zone 1 and Zone 2 explosive hazardous areas with matched safety barriers. Each ILP-1 undergoes ultrasonic signal amplitude calibration, air tightness pressure test and long-term power aging screening before factory delivery, with unified impedance and frequency parameters for each batch of products. There are no mechanical moving wearing parts inside the probe assembly. Daily maintenance only needs regular cleaning of the front filter screen and annual calibration inspection according to gas medium cleanliness.

Matched with 95C2001 installation fixtures and GF868 host equipment, it forms a complete flare gas emission metering system, satisfying environmental protection emission data filing, flare system energy-saving control and pipeline leakage monitoring requirements. It is widely applied to refinery flare pipelines, chemical plant waste gas discharge pipelines, offshore platform flare monitoring and thermal power boiler tail gas measurement scenarios.
