1、 Overview
The flow and head efficiency monitor is an intelligent digital instrument with a single chip microcomputer as the core to process standard signals. It forms a flow and head efficiency device (see Figure 1) with a three valve manifold, a differential pressure transmitter, a differential pressure side transmitter for water head measurement, and a power transmitter, forming a water turbine flow and head efficiency monitoring system.

3、 Principle
The flow through the turbine is measured by ultrasonic method. The flow of the outlet turbine is calculated according to the relationship between the flow Q and the sectional area S1 of the ultrasonic velocity measuring device V pipe: Q=V * S1, where V is the ultrasonic velocity measuring coefficient.
