Understanding Metering and Regulating Stations and Its Part

This is the third post of city gas series. Please check the first post about how to calculate city gas requirement and the second post about city gas distribution network part 1.

In previous post, I share you one important part of city gas distribution equipment which is Metering and Regulating Stations (MRS). For review, the function of MRS is to monitor flow rate of gas and to reduce gas pressure thus it meets requirement. Gas pressure is reduced from more than 16 bar to 5-15 bar in MRS. I checked in “City Gas Network Handbook” published by Indonesian Government, maximum pressure of city gas distribution system is 7 bar, although in reality, gas operating pressure is not that high.

I personally think term metering and regulating stations is not right. The best call that represents actual condition of equipment is regulating and metering stations. Why? Because the gas pressure is regulated first, then it is metered, not otherwise.

In this post I want to introduce you every part of metering and regulation stations.
