Automatic capacity detecting method and device for irregular vessel cabin

The invention relates to an automatic capacity detecting method for an irregular vessel cabin which is characterized in that a pressure water source passes through a water pipeline, is subjected to the pressure reduction and pressure stabilization by a pressure reduction and stabilization valve (4), and then is subjected to the flow measuring by a flow meter (8), further is subjected to the temperature measuring by a first temperature transducer (10), and flows into an irregular vessel cabin; a pressure transmitter (6) is used for detecting the water pressure of the water outlet end of the pressure reduction and stabilization valve (4); a level gauge (12) is used for measuring the liquid level inside the irregular vessel cabin in a real-time manner; a second temperature transducer (13) is used for measuring the liquid temperature inside the irregular vessel cabin in a real-time manner; and a control system is used for obtaining the volume of the corresponding liquid level of the vessel cabin according to the flow data measured by the flow meter (8) and the liquid level measured by the level gauge (12), and performs the volume rectification according to the temperature difference of the first temperature transducer (10) and the second temperature transducer (13). According to the invention, the labor intensity of the operating personnel is reduced, the working efficiency is improved by more than two times, so that the automatic capacity detecting method and device have very high application value.
