Calibration and Proving of Gas Meter - Kalibrasi Gas Metering

Why We Need Proving?

• Orifice plates can become damaged, bearings on Turbine Meters can wear and dirt and trash can accumulate on flow conditioners and in piping
• Trash can accumulate on straightening vanes and Ultrasonic meters and other meters can become dirty causing the meter to error
• The inputs into flow computers and other electronic devices can be changed by mistake causing errors in measurement
• New meter installations can have debris from construction caught on the straightening vanes or in the meter itself.
• Proving checks not only the meter, but also the complete meter system
• One of the more important reasons for meter proving in the case of Custody Transfer is to give both the buyer and seller confidence the volumes they transfer are acceptable to both the buyer and seller, thus eliminating disputes
