Small tanker measurement accuracy analysis

Small fuel dispensing pump metering accuracy analysis: Small tanker flowmeter is generally performed using a standard amount Jane metrology, the oil volume measured value indication is shown on the counter volume, standard volume of fluid injected into the vessel is another indication of the volume occurs, the difference between the two values is called meter absolute error of the measured volume, the relative error E for its measurement accuracy: E = (VJ-Vs) / Vs x100% of which: VJ- metered the oil indicated value on the display panel. The actual volume measured in standard containers Vs- indication. Visible small tanker still has his error exists.
From the above equation, E> 0, it means more than VJ Vs, measurement meter display that shows the value of the container is greater than the standard, less hair oil tanker to the user. E <0, ie, the oil tanker multiple users, for two reasons showing error generated more complex, including the systematic errors and random errors. Systematic errors may be suitably compensated by adjustments. We use the adjustment mechanism to adjust the actual displacement flow meter, flow meter is to compensate or correct systematic errors, in order to improve the accuracy of the meter. Factors affecting measurement error problem of small tankers also have a lot of. So sometimes can not blindly suspect misconduct fuel dispensing equipment
