1.Flow measurement and pressure loss compensation for natural gas long-distance transmission pipelines.

In natural gas long-distance transmission pipelines, the FD3051SDP cooperates with throttling devices such as orifice plates and Venturi tubes to accurately measure pipeline differential pressure for flow calculation. Equipped with built-in temperature self-compensation mechanism and dynamic differential pressure correction algorithm, it can correct measurement errors caused by medium temperature, pressure changes and pipeline friction resistance, with comprehensive measurement accuracy within ±0.5%. Optional static pressure levels (16MPa/25MPa/40MPa) adapt to high-pressure transmission conditions, and corrosion-resistant diaphragms isolate corrosive impurities in natural gas. Supporting RS485 protocol to connect to the pipeline SCADA system, it real-time feeds back flow data and pressure loss status, providing data support for pipeline transmission efficiency optimization and leakage warning, adapting to the operation needs of remote outdoor and unattended stations.

2.Wellbore differential pressure monitoring on oil and gas drilling platforms.

In wellbore operations of oil & gas drilling platforms, the FD3051SDP can real-time monitor the differential pressure between the wellbore annulus and drill pipe, providing key data for kick and blowout risk warning. With Ex ia II C T6 Ga intrinsic safety explosion-proof certification, it can be directly deployed in the explosion-proof area of drilling platforms, withstanding high-frequency vibration and high-pressure impact. The wide operating temperature range (-20℃~80℃) adapts to marine salt spray and extreme climate environments; the monocrystalline silicon sensing element has fast response speed, capable of capturing small differential pressure fluctuations. Linking with the drilling control center via 4-20mA signal, it real-time adjusts drilling fluid circulation parameters to ensure safe drilling operations. Its robust structure and corrosion resistance can adapt to erosion from mixed media such as mud and oil & gas during drilling.
