US 10,294,914 B2 · Hydraulic installation and method of operating such an installation

Abstract

The present invention relates to a hydraulic installation where sediment concentration in the water flow circulating through the cited installation is monitored continuously. According to the invention, the hydraulic installation comprises a pressure-reducing device and a primary sensor: the pressure reducing device decreases the pressure and discharge of upstream water flow, comprising sediments, allowing that the primary sensor can operate continuously measuring sediment concentration from the upstream water flow. The hydraulic installation also comprises a calibrating device, providing the primary sensor with a reference value to be used for comparison matters and for establishing the content of sediment in the water flow.

Dependent claims

A hydraulic installation for operating a hydraulic turbine, wherein sediment concentration in a water flow circulating through the installation is monitored, the hydraulic installation comprising:

a pressure-reducing device;
and
a primary sensor,
wherein the pressure-reducing device is designed to create hydraulic resistance with internal flow speed less than 15 m/s as a function of an operating head in the hydraulic turbine in such a way that the primary sensor can be operated continuously to measure sediment concentration in the water flow, and
wherein the primary sensor is adaptable to face minimal effects of silt erosion and to augment service life.
