Automated field calibration for the oil and gas industry
Technicians that maintain and troubleshoot process automation systems used in refineries, pipeline custody transfer applications, or pumping operations know that there are thousands of sophisticated devices required to perform countless critical operations ceaselessly, accurately, and reliably. Those devices require regular inspection, testing, calibration, and repair to protect the health and safety of the public. Businesses and governments require highly specific documentation of those maintenance and calibration tasks performed on these critical assets.
Calibrating Gas Custody Transfer Flow Computers
Gas custody transfer flow computers that calculate flow by measuring the differential pressure across a flow restriction, such as an orifice plate, require special calibration to perform at optimum accuracy. In custody transfer applications where the buying and selling of commodities like natural gas is involved, calibration checks are performed frequently as a matter of fiduciary responsibility. For the purpose of this application note, the use of gas custody transfer flow computers in the natural gas transmission industry is referenced.Flow computers need multiple measurements to calibrate each device. In the normal application, three measurements are made: volumetric flow, static (line) pressure and temperature. A calculation is performed using this data to determine the actual mass of the gas flowing through the pipeline.
Calibrating pressure transmitters and switches in potentially explosive atmospheres
Pressure calibration can be a difficult challenge in the best of environments. Doing so in an area that has the potential for explosion takes the degree of difficulty to another level-one where the technician needs proper training and equipment. This article will demonstrate the practical application of pressure calibrators designed to perform calibrations in potentially explosive environments.
