 The CALDON® Ultrasonic Technology Center is located near Pittsburgh, Pennsylvania. The centerpiece of this facility is the Cameron Hydrocarbon Calibration Laboratory.This flow laboratory is unequalled and sets Cameron apart from other ultrasonic meter suppliers in three distinctive ways.
Each Caldon LEFM 200 Series ultrasonic flow meter is calibrated in this laboratory over a Reynolds number range that corresponds to the actual Reynolds number range the meter will encounter in the field, when possible. This process ensures that once the meter is installed and operating,performance will be unaffected by changes in flow rate and liquid viscosity. The ability to calibrate in-house will virtually eliminate the need for Cameron to use independent facilities, thereby dramatically reducing delivery cycles.
 When you talk about a flow laboratory sooner or later you will come around to talking about accuracy, or as it’s called by metrological experts, the laboratory’s measurement uncertainty. To calibrate a meter it is necessary to compare its registration to a “known volume”, i.e., if 1,000 barrels of oil are passed through the meter, does it register 1,000 barrels? The uncertainty of the flow laboratory deals with the errors that might affect the “known volume” and how it compares to an international standard. When a meter has been calibrated in a flow laboratory with a low measurement uncertainty, its measurement in the field will be more accurate. The target uncertainty of the Cameron Hydrocarbon Calibration Laboratory is 0.05%.
The extreme stability of the flow rate and temperature achievable at the Cameron Hydrocarbon Calibration Laboratry provides Cameron engineers with an unserpassed tool for conducting fundamental research. This has contributed to better understanding of the phenomena that affect ultrasonic flow meters.
