Flowmeter Calibration

Calcolo della calibrazione dei misuratori di portata utilizzando un rilevatore volumetrico di riferimento.

"Flowmeter calibration" is an App that allows to calculate in a simple and practical way the test parameters resulting from the calibration of liquid flowmeters not subjected to pressure using a reference volumetric prover.

This App is ideal for Metrological Institutes and Fuel Storage and Distribution Plants, where it is required to verify that the flowmeters are dispensing the fuel with an error within the limits allowed by law.

The admitted data can be in both the SI (International System of Units) and the English System

The data required for the calculation are:

- API or Fuel density; If the API is used, the calculation will be made based on table 6B and if density is used, table 54B will be used

- αv; Thermic dilatation coefficient of the volumetric prover

- T1, T2, T3; Thermometers of the volumetric prover

- Vp; Volume indicated by the volumetric prover

- Vf; Volume dispatched by the flowmeter

The results that are calculated are:

T = Average temperature of the volumetric prover

CTL = Correction factor for the effect of temperature on liquid

CTS = Correction factor for the effect of temperature on steel, also called VCF

Vpc = Volume corrected of the volumetric prover

E, E% = Error and percentage error
