Vehicle-mounted high-precision fluid metering device and metering management system

Abstract

The invention discloses a vehicle-mounted high-precision fluid metering device and a metering management system, and relates to a vehicle-mounted accurate flow metering mechanism, and a vehicle-mounted flow metering real-time management system. The fluid metering device sequentially consists of a section of straight pipe (2), a solenoid valve (7), a section of filling flexible pipe (11) and a filling gun (12); the metering management system comprises a control module, a radio frequency integrated circuit (RFIC) double reader, a liquid crystal display, and an operation panel, a global system for mobile communication (GSM) communication module, a background database management center, a filling vehicle integrated circuit (IC) card, and a filled vehicle IC card. The flow metering device has the advantages of high metering precision, corrosion resistance, high repeatability and abrasive resistance and the like; the metering management system realizes the function of a mobile filling station, and provides a better management platform for a manager. The fluid metering device and the metering management system can accurately meter the flow of the fluid, and are suitable for metering of quantity acceptance and trade settlement of the media which are loaded by an oil tank carrier vehicle and other special liquid carrier vehicles.

Description

technical field [0001] The invention relates to a vehicle-mounted high-precision flow metering device and a metering management system thereof. Background technique [0002] At present, most of the tank trucks or other special vehicles for liquid transportation are not equipped with on-board metering equipment, and a small number of vehicles are installed with ultrasonic flowmeters or mechanical rotor-type metering equipment. The above metering equipment has low accuracy, poor repeatability, and inconvenient use. Defects, after being installed on the car, due to the different road conditions in different places, the use time is a little longer, and the degree of damage to the metering equipment is aggravated, making it lose its proper use, and it cannot be an accurate basis for metering acceptance. Moreover, gas will be mixed in the flowing liquid, which will cause errors in flow measurement. In addition, in order to measure the flow rate accurately, according to the nation...

AI Technical Summary

Problems solved by technology

For liquid transport vehicles, due to space constraints, sometimes it is difficult to meet the requirements of the length of the straight pipe

In addition, due to the strong mobility of the vehicle, it is also difficult to measure and manage the transported liquid

For example, the finished oil tanker, the current price of refined oil is high, and the oil tanker is moving outside, it is difficult to ensure that the oil is not lost, so real-time management and monitoring of corresponding vehicles is also an important issue
