Irregular tank volume measuring system and method

Abstract

The invention relates to an irregular tank volume measuring system and method. The measuring system comprises a water injection assembly, a measuring assembly, a tank and a control assembly. The wateroutlet end of the water injection assembly is connected with the water inlet end of the measuring assembly; the water outlet end of the measuring assembly is connected with the water inlet end of thetank body; a water pumping assembly is arranged on the measuring assembly; a pipeline on the water pumping assembly penetrates into the measuring assembly and is flush with the nominal liquid level of the measuring assembly; the control assembly comprises a monitoring unit and an electric control unit; the electric control unit is electrically connected with the water injection assembly, the water pumping assembly and the monitoring unit, the monitoring unit monitors the liquid level change of the nominal liquid level of the measuring assembly and feeds back the liquid level change to the electric control unit, and the electric control unit controls the water pumping assembly to pump water from the monitoring unit. When the injected water amount exceeds the nominal capacity of the measuring assembly, the water pumping assembly is started to pump out water until the water injection liquid level is flush with the nominal liquid level; interference of bubbles on measurement of the volumeof the tank body in the water injection process is reduced, and the accuracy of a tank body volume measurement result is guaranteed.

Description

technical field [0001] The invention relates to the technical field of measurement, and more specifically, to a system and method for measuring the volume of an irregular tank body. Background technique [0002] Automobile oil tank truck is a special vehicle for road transportation of liquid petroleum and chemical products. It is a metering oil tank installed on the car. It is not only a storage and transportation tool, but also a measuring instrument for oil product transfer and trade settlement after passing the inspection. , belongs to the national compulsory verification of working measuring instruments. As the main measuring instrument for oil transportation, automobile tank trucks have become more and more prominent in the measurement of tank truck capacity. People's concept of legal system has gradually improved. In order to ensure the fairness and justice of oil product transfer between trading parties, accurate measurement of tank truck capacity is required. Theref...

Problems solved by technology

[0003] Existing tank capacity verification generally adopts the capacity comparison method or the flow meter method. The capacity comparison method is often to pass water into the tank, stop the water flow when the water is full, and calculate the remaining water volume to know the tank capacity. Capacity, but this method is mostly measured manually, and when pumping water into the water storage bucket, there may be air bubbles in the water in the storage bucket, resulting in the amount of water injected into the water storage bucket may often be higher or lower than the water storage bucket Nominal capacity, which affects the accuracy of tank volume measurement
