Terminal Proving


Loading Rack & Offload Meters
Due to the improved efficiencies of small volume provers a meter can be proven for a single flow rate with under 800 gallons, and an entire rack with six loading arms can be proven in half a day. The number of product offloads is significantly reduced compared to volume metric proving. On single product loading arms the meter can be proven as a truck is loaded.


Why Add a Master Meter?
By adding a master meter in series with the small volume prover we are able to perform two checks on every proving run. The first check is with the small volume prover directly on the loading rack meter. The second check we are also able to use the master meter to check the entire loading rack system. In addition the master meter allows for increased trouble shooting when meter and system problems are found.


Loading Rack Services


Additive Meter Calibration
Additive meters on the loading rack need to be calibrated regularly to assure that the proper amount of additive is being injected into every load. Proper additive concentration is important to meet regulatory requirements, and to minimize over injection due to the high price of additive.


Temperature Probe Calibration
Temperature is the largest factor in the gross to net conversion of product totals. Incorrect temperatures at the loading rack can lead to significant product loss. By the calibrating the temperature probe in situ the entire system is checked as a unit rather than as individual pieces. This lowers the possibility of problems and can reduce uncertainty.


Loading Rack Maintenance Services
Proper maintenance of loading rack components will greatly affect measurement accuracy and loading rack control. Proper tuning and maintenance of control valves will assure proper product shut off and improve blending accuracy. Proper cleaning of strainers helps to minimize the disturbances going into the meter for better measurement.


Pipeline Provings


Ball Prover Calibration
By using the Master meter method to calibrate pipeline ball provers there is no need to drain down the prover or introduce water into the prover. There is no need to flush the prover. It is not necessary to isolate the prover for an extended period of time. Provings can be accomplished within one day in most instances. There is no need to dispose of contact water. The prover is proven at a much higher flow rate than water draw proving limiting the affect of imperfections in the prover lining.


Meter Calibration
Whether it is small pipeline meters or transfer meters frequent provings will help to verify all product volumes.
