Embodiment 1

[0023] like figure 1 As shown, a measure-in and measure-out dual calibration device for calibrating the volume of a horizontal metal tank includes: a horizontal metal tank A1, a horizontal metal tank B2, a standard device 3 and a water pump 4. Horizontal metal tank A1 and horizontal metal tank B2 are oil storage tanks to be calibrated, buried below the ground. The horizontal metal tank A1 is provided with a manhole A11 and an oil measuring hole A. The upper ends of the manhole A11 and the oil measuring hole A are respectively exposed to the ground, and the lower ends are respectively communicated with the inner cavity of the horizontal metal tank A1. The bottom surface of the inner cavity of the horizontal metal tank A1 is provided with a measurement reference point of the tank A, and the measurement reference point of the tank A is located directly below the oil measuring hole A. The horizontal metal tank A1 is connected with a liquid level gauge A12, and the liquid level g...

Abstract

The invention provides a meter-in and meter-out dual calibration device and method for calibrating the volume of a horizontal metal tank, and relates to the technical field of measuring. The initial volume of a tank A filled with water is Vm, a tank B is empty totally, and a numerical value of a liquidometer A and the numerical value of a liquidometer B are recorded respectively; water is sucked from the tank A, metered through a standard and injected into the tank B repeatedly, and numerical values of the liquidometers A and B are recorded respectively; the liquidometer B of the tank B corresponds to the injection water volume, and calibrated tank volume data is obtained after calibration is completed; the initial volume value Vm is obtained after water in the tank A is sucked completely, the each reading of the liquidometer A corresponds to the remaining water volume in the tank obtained by subtracting the volume of sucked water from Vm, the volume is converted after calibration is completed, and calibrated tank volume data is obtained. The technical problem that an existing metal storage tank volume is large in volume calibration error and low in efficiency is solved. The device and method have the advantages that equipment input is saved, energy consumption is lowered, calibration efficiency is high, the meter-in and meter-out working modes are calibrated, a result is reliable, operation is easy, and adaptability is good.

Description

technical field [0001] The invention relates to the field of measurement technology, in particular to a device and a calibration method for calibrating the volume of a metal storage tank. Background technique [0002] Horizontal metal tanks are generally buried in the ground and are used to store gasoline, diesel, kerosene and other fuels. As a measuring instrument for measuring and storing liquids, they are widely used in various industries. The purpose of volume calibration for horizontal metal tanks is to give the corresponding volume value of the target tank at a certain interval of liquid level to form the so-called "tank volume data". At present, the methods for calibrating the volume of horizontal metal tanks mainly include geometric measurement method, capacity comparison method and standard flowmeter method. The geometric measurement method requires the operator to go down to the actual measurement in the tank, and then process it with an idealized model to obtain ...
