1. Overview
The DSJ multi-function flow hydraulic parameter monitoring device is an intelligent digital monitoring device that uses a single chip microcomputer as the core to process standard signals. It can accurately measure and calculate the passing flow, water head, power and water consumption rate of the hydraulic turbine, and provide a reference for the economic operation and adjustment of the hydraulic generator set.
