Metering and Regulating System of Self-used Gas

Application

The system integrates the functions of filtering, heating, regulating, metering, distribution, venting, relief, leak alarm and automatic switching, having the characteristics of high explosion proof requirement, multiple regulation steps, wide regulation range, good safety performance, intermittent gas supply and high metering requirement.

In a typical pipeline station the sequence is: Station inlet → Filtration → Regulation → Metering → Station outlet.

Scope of supply

• Characteristics 3D This system is suitable to manned(unmanned) operation or attended natural gas distributing station, metering station, storage and distribution station, regulator station and etc.
• High requirements for the heater in the system:special explosion proof performance,IP code and the manufacturing requirement of the equipment body, adopting direct or indirect electric heater,the safety protection measures of heating speed, heating temperature and dry combustion prevention effect the system safety directly.
• System Characteristics Available in two electric heating modes:direct and indirect Using intercepting pressure regulator valve with pressure stability and good closing performance at low flow condition Adopting the safety protection measure of dual safety shut-off valves Regulating accuracy of ±1%, wide adjustable ratio Equal percentage characteristic (logarithmic characteristic) The shut-off reaction time is less than 1s Automatic shut-off, travel transmission, travel indicator (local and remote) can be provided Using special flowmeter in low flow situation

Capacity, design conditions and scope of supply are confirmed per project.
