Boiler liquid level meter based on ultrasonic ranging

Abstract

The invention relates to a boiler liquid level meter based on ultrasonic ranging. The boiler liquid level meter is characterized by further comprising a main control module, an ultrasonic ranging module and an anti-interference module; the ultrasonic ranging module is arranged on the top of a boiler inner container; the anti-interference module is arranged on the bottom face of the boiler inner container; the anti-interference module and the ultrasonic ranging module are oppositely arranged; the main control module is electrically connected with the ultrasonic ranging module; the anti-interference module comprises an ultrasonic wave absorption module, and the ultrasonic wave absorption module absorbs sound waves penetrating through the liquid level to reach the bottom face of a boiler. The liquid level is intelligently read through the ultrasonic ranging module, a touch screen displays the liquid level in real time and can adjust and control the liquid level in real time, workers can conveniently master the condition of the boiler in real time, and the intelligent degree is high. The liquid level height integrates liquid level fluctuation compensation and temperature compensation, so that the accuracy of ultrasonic ranging reading is improved. The anti-interference module absorbs the sound waves penetrating through the liquid level to reach the bottom face of the boiler, interference caused by the sound waves reflected by the bottom face in the boiler is reduced, and the accuracy of the ultrasonic ranging reading is improved.

Description

technical field [0001] The invention relates to the field of liquid level measurement, in particular to a boiler liquid level gauge based on ultrasonic distance measurement. Background technique [0002] The boiler is a kind of energy conversion equipment. The energy input to the boiler includes chemical energy and electric energy in the fuel. The boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of heat energy. The original meaning of the pot refers to the water container heated on the fire. , The furnace refers to the place where fuel is burned, and the boiler includes two parts: the pot and the furnace. The hot water or steam generated in the boiler can directly provide the required heat energy for industrial production and people's life, and can also be converted into mechanical energy through a steam power device, or converted into electrical energy through a generator. Boilers that provide hot water are called hot water boilers...
