Explain with small example that control Flow , Pressure and Temperature of Gas and Analyzer (GC). Explain required instrument Loops Safety Wiring
metering skid, is a framed device on which various assemblies are installed. These include solar panel, meter prover loop, control valves, meter run, and ancillary control houses to name a few. The main use of a Meter Skid is in custody transfer meter, whereby it is used for the determination of financial estimates. Every Meter Skid can be composed of the process gas chromatograph and one or more flow meters. The Meter Skid also measures the gas and decreases the pressure of gas at metering stations.
A metering skid is a fabricated frame of heavy I-beams on which the meter run, the meter prover loop (in some instances and ancillary control houses, solar panel , batteries, transmitters, control valves and other equipment as required is installed) In most cases a metering skid is a Custody Transfer Meter where the monetary calculations are determined. In most cases the actual flow meter is an orifice plate. this means for large diameter meter runs, the skid base can become quite long
A Metering Skid a fabricated platform with all necessary piping, Valves filters and instruments to perform the metering and process function. It is a single unit that contain parts of all that is required to perform necessary processes The skid is fabricated and tested off site and is then shipped and installed as a functional unit.
PROPORTIONAL INTEGRAL DERIVATIVE pid CONTROL WITH CONTROL VALVES TO CONTROL FLOW AND PRESSURE
i can make control about flow with throttle valve ,if it is hydraulic system
.about temp which use thermal sensor to control in temp as example thermostat in refregeration and air conditions
