How do you measure the amount of oil when you fill the tank?
The simplest way is to weigh the tanker, oil before and after pumping two weighing, weighing the weight difference is pumping quantity (each weighing fee of 20 yuan).More accurate way to install mass flow meter, but the price is very expensive.
Liquid level instrument, one of the necessary equipment of the gas station, is inserted from the manhole of the tank until the bottom of the tank. The height of the liquid level is centrally displayed by the central controlLiquid level measurement is a very broad field in industrial measurement. In the fields of petroleum, chemical, food and nuclear energy, a large number of industrial liquids need to be measured accurately to facilitate the control of the production process and operation process. The float level instrument used in the tank level measurement of gas station is difficult to be popularized in the gas station because of its inconvenient installation. Tsinghua University has successfully used ultrasound technology in SGU
When filling the tank, the amount of oil measured is usually measured by a liquid level meter.
Electronic level meter is one of the necessary equipment for gas station, inserted from the tank manhole, until the bottom of the tank, the oil into the hole from the bottom level, according to the principle of communicating vessels, oil will generate pressure, through the computer calculation of pressure value into the height value, the control display liquid level height.
There are no old tank liquid level detector, is the first to measure the height of oil tank, the factory has a "tank capacity table", is the volume and height of the table, with a height, according to the amount of residual oil tank capacity table.
