Constant-flow bubble water level measuring system and method

The invention discloses a constant-current bubble water level measuring system and method, and the system comprises a constant-current bubble water level assembly, an ultrasonic comparison and correction assembly, and a control assembly which is independently connected with the constant-current bubble water level assembly and the ultrasonic comparison and correction assembly. The control assembly is used for obtaining data provided by the ultrasonic comparison and correction assembly and the constant-flow bubble water level assembly and obtaining a water level value through processing according to the obtained data. Through the disclosed content, data correction can be carried out on the constant-current bubble water level gauge with temperature compensation by utilizing ultrasonic ranging, and the detection precision is improved. In practical application, the device can resist the influence of various factors such as temperature environment and flow surge and the constant-voltage output change of the device.
