Wireless automatic verification device for tanker capacity of vacuum insulation standard metal gauge

Abstract

A wireless automatic verification device for fuel dispenser capacity of a vacuum-insulated standard metal gauge, which belongs to the technical field of capacity standard verification devices, and aims to solve the problem that the existing standard metal gauge fuel dispenser capacity verification device uses a communication cable to transmit data and its cable material The problem of easy loss. The data acquisition wireless transmitter it uses is connected to the main body of the vacuum insulation standard metal gauge by a connecting seat. The data acquisition circuit and the wireless transmission module are sealed in the explosion-proof shell of the transmitter. The data acquisition circuit is connected to the muzzle temperature sensor and the gauge. The temperature sensor of the main body of the instrument is respectively inserted into the temperature measuring hole sleeve of the main body of the vacuum insulation standard metal gauge and the temperature measuring hole sleeve of the upper cone. The hysteresis expansion liquid level gauge is equipped with a signal line connected to the data acquisition circuit. The output is connected with the wireless sending module through the digital communication port, and the wireless sending module is connected with the wireless receiver and the monitoring computer. It has a simple structure and is suitable for testing various types of fuel dispensers and liquid measuring instruments.

Description

technical field [0001] The invention belongs to the technical field of capacity standard verification devices and relates to a fuel dispenser capacity verification device for a vacuum heat preservation standard metal gauge. Background technique [0002] With the continuous development and technological progress of standard measuring instruments, the technical requirements for fuel oil filling mechanical capacity verification devices are also getting higher and higher. In the known technology, the existing standard metal gauge tanker capacity verification device is mainly composed of a standard metal gauge body and a thermometer. By manually reading the standard metal gauge liquid level height, the oil temperature at the outlet of the gun, and the temperature inside the container Oil temperature, and then the detection capacity value is obtained by manual calculation, and there is also an automatic collection temperature sensor, which transmits the data to the computer throug...
