Embodiment Construction

[0035] The present invention will be further described below in conjunction with the examples.

[0036] Such as figure 1 As shown, a device for monitoring the remaining amount of liquefied petroleum gas is provided with a tank 1 and a gas delivery pipe. One end of the gas delivery pipe is connected to the tank 1 and the other end is connected to a gas stove 5 . There is a pressure regulating valve 4 on the gas pipeline, an angle valve 2 is installed on the tank 1, and the angle valve 2 is directly or indirectly connected to the signal acquisition unit 3. The signal acquisition unit 3 adopts a temperature sensor and a pressure sensor, and can also use a temperature sensor. The pressure sensor is used to collect the pressure and temperature of the liquefied gas in the tank 1. The signal collection unit 3 can be directly installed on the angle valve 2, or it can be installed on the gas pipeline between the angle valve 2 and the pressure regulating valve 4. A controller can also ...

Abstract

The invention provides a method and device for monitoring the remaining amount of filled liquefied gas. A tank and a gas delivery pipe are arranged, an angle valve is arranged on the tank, a signal acquisition unit is connected to the angle valve, and the signal acquisition unit is used for acquiring the pressure and temperature of the liquefied gas in the tank. The technical problem that in the existing liquefied gas using process, a user cannot visually judge the gas volume in a tank, and much inconvenience is brought to use is solved. The method and the device can be widely used for monitoring the residual amount of the filled liquefied gas.

Description

technical field [0001] The invention relates to a method and a device for monitoring liquefied gas, in particular to a method and a device for monitoring the remaining amount of liquefied gas in filling. Background technique [0002] With the development of society, liquefied petroleum gas has been widely used in industrial production and residential life. It is generally used in the form of filling. When it is needed, it will be delivered by the merchant and charged according to the price of the can. It is difficult for users to judge the authenticity of the liquefied petroleum gas in the tank. In addition, during the use of canned liquefied gas, only by significantly reducing the firepower can we find that the gas in the tank is insufficient and needs to be refilled, so it is impossible to make a judgment in advance, which will affect the use. [0003] The utility model patent "a real-time monitoring device for the remaining amount of liquefied gas" (application number 201...
