Water Draw Calibration

Maintenance efforts of the master meter method are easier than the gravimetric method. However, the guidelines of master meter method have not been established completely. It is because the notion of relative deviations, which are used as a measure and for comparison calibration, is not clearly understood.

On the other hand, the system uncertainty, which is typically used as the calibration and measurement capability of the gravimetric flow standards, are understood very well. In this study, a complete explanation on the master meter method is attempted. First, appropriate calibration conditions are assumed.

Second, a suitable calibration procedure is suggested. Third, a mathematical model for the relative deviations is described. Fourth, uncertainty factors of the relative deviations are evaluated.

Finally, two examples of the comparison calibration are explained in detail. In the examples, it is found that the master meter method can achieve the measurement uncertainty as low as 0.

Abstract Master meter method is an efficient way to calibrate flow meters with less time and costs. References 1. Article Google Scholar 5.Since inception, the API Petroleum Measurement Manuals were written to design and define test solutions to reduce the uncertainty and improve the accuracy of all petroleum measurements.

As technologies evolve, so do the written standards. The continuous growth and use of Unidirectional Captive Displacement Provers has been influential in the adoption of these changes. When using volume for water draw certification of an SVP, can sizes from 2 gallons to gallons displaced volumes used for BPH to 35, BPH flow rates respectively are much smaller than previously required for ball type displacement provers.

The uncertainty in the measurement of volume varies with the size of the can. The smaller the can size, the greater the uncertainty. Additional uncertainties can stem from reading the calibrated cylinder, the temperature and other variables required to correct to the actual volume measured.

The uncertainty of this measurement is fixed and defined by a scale and is influenced by the buoyancy due to pressure in altitude changes. When comparing gravimetric to volumetric water draws, results show a dramatic improvement decrease in uncertainty when the gravimetric method is used.

This decreased uncertainty becomes more pronounced as the Prover volumes get smaller. Manufacturers of SVP's have recognized the importance of accurate volume calibrations and employed the gravimetric method in their final acceptance testing for years.

The calibration procedure known as the volumetric water draw method establishes the known volume of the pipe prover at base conditions. This method is performed by displacing water from the prover into field standard test measures. Meter Engineers has highly trained technicians to calibrate your unidirect prover, bidirect prover, tank prover, or compact prover. Each water draw unit consists of a water reservoir, stainless steel test measures certified by NIST, certified thermometers, pressure gauge and large centrifugal pumps to accommodate any size sphere or piston prover.

All of our portable water draw calibration units are completely self-contained. Equipped with associated pipework, hoses, 4-way valve, and on board generators. This method establishes the volume of the measurement section in the prover at base conditions utilizing a weighing system consisting of scales, certified weights, and containers to hold the water.

Gravimetric Water Draw Calibration Process Coming soon… This method establishes the volume of the measurement section in the prover at base conditions utilizing a weighing system consisting of scales, certified weights, and containers to hold the water.A flow meter is a test device used to measure the flow rate of process fluids and gases in industrial plants and facilities.

The flow rate refers to the speed at which a process fluid is moving through pipelines, orifices, or vessels at a given time. Control and instrumentation engineers measure this value to monitor and regulate the speed and efficiency of industrial flow processes and devices. For example, a bathroom scale that indicates 10lbs when nobody is standing on it needs to be recalibrated to indicate an initial zero value.

In industrial settings, flow meters are periodically calibrated to ensure that measurements are accurate allowing operations to proceed in a safe and timely manner. Flow meter calibration is the process of comparing the pre-set scale or metering of a flow meter to a standard scale of measurement and adjusting its metering to conform to the standard. Calibration is an essential aspect of instrumentation in a broad range of industries that require high-accuracy measurements with a negligible percentage of error e.

Flow meters are calibrated by comparing and adjusting their metering to correspond with a predefined standard. Flow meter manufacturers typically calibrate their products in-house after production or send them to an independent calibration facility for adjustment. Flow meter calibration involves comparing the measurements of a flow meter in operation to that of a standard flow measurement device under the same conditions and adjusting the scale of the flow meter to be in close agreement with the standard.

Flow meter recalibration involves calibration of a flow meter which is already in use. The main difference between the two procedures is that flow calibration is done before the meter is sent out for use while recalibration is done after the flow meter has been in operation for a while.

Software tools can also be used to verify the accuracy of measurements after a flow meter has been calibrated. Liquid flow meter calibration can be done in several ways, but always involves comparison and adjustment of the flow meter under test to conform to a standard.

In the U. The master flow meter is usually a device whose calibration is set to a national or international standard. Gravimetric calibration is one of the most accurate and cost-effective volumetric and mass flow meter calibration procedures. The gravimetric method is ideal for liquid flowmeter calibration in oil, water purification, and petrochemical industries.

In the piston prover flow meter calibration procedure, a known volume of fluid is forced through a flow meter under test. The piston prover is a cylindrical device with a known internal diameter. The piston prover contains a piston which produces volumetric flow by positive displacement. The piston prover method is ideal for ultrasonic flow meter calibration, fuel flow meter calibration, and turbine flow meter calibration to a high degree of accuracy.Pipe or compact provers are often used in Metering Systems for frequent calibration on actual process conditions.

The base volume of these provers needs to be regularly determined to the lowest possible measurement uncertainty. Prover calibration is recommended to:. A waterdraw calibration unit is generally portable and consists of a water reservoir, a low-pressure centrifugal pump, associated pipe work, hoses and a four-way valve.

The centrifugal pump circulates water from the reservoir through the prover. To reduce the uncertainty caused by test measure scale reading errors, the number of test measures filled during a calibration pass shall be kept to the minimum possible, based upon the volume of the prover and the number and sizes of the test measures available.
