燃气计量撬 / CNG 减压计量撬Metering skid / CNG metering skid
以计量为核心功能的撬装单元，兼顾调压与切断，用于贸易结算、企业内部核算与过程监控。Metering-centred skid with regulation and shut-off, for custody transfer and internal accounting.
产品概述Product overview
计量撬的选型难点不在流量计本身，而在“流量范围”和“结算方式”。用气有大小月、昼夜差异大的场合，单一流量计的量程比往往撑不住，需要双表并联或宽量程比表；贸易结算还要考虑温压补偿、整流直管段与检定证书。泰燃在 200 Nm³/h 燃气计量撬（HBTR-NG/200）与 300 Nm³/h CNG 减压计量撬（RTQ300/250）上都按实际用气曲线定表，而不是按管径配表。Meter selection turns on rangeability and settlement method, not pipe size; units are sized to the actual demand curve.
撬上典型顺序：过滤 → 切断 → 调压（CNG 场合含两级减压与换热）→ 整流 → 计量 → 出口。仪表信号可上传至用户 DCS 或能源管理平台。Filter, shut-off, regulation, straightening, metering, outlet; signals can go to DCS or an energy platform.
