Electrical Performance & Core Function

This main board collects echo signals from ultrasonic sensors, calculates sound transit time difference and converts data into instantaneous flow rate and total flow volume via dedicated built-in algorithms. It carries bus interfaces to drive display panels, analog output boards, Ethernet and HART communication modules synchronously. Multiple layers of surge absorption and EMI filtering circuits protect core chips against grid surges and field electromagnetic noise. All calibration coefficients and user setup parameters are stored in nonvolatile storage without data loss after power cut. Core electronic devices are screened through high-low temperature aging to sustain long-term stable computing and control performance.

Structural Design & Environmental Adaptability

The PCB surface is coated with moisture-proof, dust-proof and anti-corrosion conformal coating to adapt to humid, dusty and mildly corrosive working conditions in petrochemical plants, thermal power workshops and outdoor pipe gallery cabinets. The physical outline, fixing apertures and pin definitions strictly follow factory original standards for direct slot installation without rewiring. Reinforced soldering structures eliminate poor contact risks brought by long-term equipment vibration and temperature cycling, fully complying with industrial EMC specifications.

Matched Equipment & Application Scenarios

Compatible with XMT868, XMT868i liquid ultrasonic flowmeters and GF868 flare gas flow transmitters. Widely used in petrochemical medium metering, thermal power circulating water monitoring, refinery flare gas measurement and coal chemical pipeline flow statistics. It solves fatal faults including instrument startup failure, measurement disorder and each functional module communication breakdown caused by main board aging and component damage.

Stability & Maintenance Advantages

Every board passes algorithm calibration, full interface function test and continuous powered aging inspection before delivery to guarantee unified batch precision and stability. Original device configuration data will not be erased after replacement, cutting field debugging time and production downtime losses effectively. Authentic GE mainboards prevent secondary damage to peripheral sub-boards induced by counterfeit control boards. Shockproof sealed packaging meets long-term spare parts storage demands, and overall operating performance keeps steady under dry constant-temperature storage environments.
