This application discloses a method, apparatus, equipment, and medium for dynamic measurement and calibration of electronic remote
differential pressure liquid level, belonging to the field of liquid
level data processing technology. The method includes: acquiring
differential pressure signals through a secondary board to generate a raw
differential pressure data stream; determining whether the current liquid level environment is in a
steady state or a fluctuating state based on the statistical variance of the main board within a preset time window; if determined to be in a
steady state, the main board sends a digital command to the secondary board to initiate bidirectional
handshake communication, calculating the zero-point correction amount by obtaining the standard reference
signal fed back by the secondary board; if determined to be in a fluctuating state, prohibiting the calculation of the zero-point correction amount and activating an adaptive fluctuation suppression
algorithm; and calculating the final effective differential pressure value based on the zero-point correction amount and / or the
signal processed by the adaptive fluctuation suppression
algorithm, and converting it into a standard current
signal output. This technical solution can output stable and accurate liquid level signals under different operating conditions, significantly improving the stability of industrial
process control.
