Calculation and countermeasures of calibration error of high head multi-level ship lock water Level gauge

Abstract The accuracy of water level gauge data for high-head multi-stage ship locks is directly related to the accuracy and safety of the water conveyance control of the ship lock. The water level gauge of the ship lock is affected by the installation environment and other factors, and the water level data may deviate. During the operation of the ship lock, the water level gauge in the lock chamber will be calibrated regularly according to regulations. This article introduces the calculation and countermeasures for the calibration error of water level gauges in a high-head multi-stage ship lock, which can effectively control the errors caused by the calibration of water level gauges.
