AI Technical Summary

⚠Technical Problem

Existing fluid flow measurement systems in hydraulic systems face inaccuracies due to capacitance in hydraulic lines and pressure drops across flow meters, making it desirable to integrate flow sensing capability into manifolds and reduce pressure loss.

⚗Method used

A flow meter insert with a turbine and magnets that rotates with fluid flow, coupled to a sensor to detect magnetic field variations, allowing accurate measurement of fluid flow rate and direction, and is designed to be integrated into a manifold for reduced capacitance and pressure drop.

🎯Benefits of technology

The solution provides accurate fluid flow rate and direction measurement with reduced pressure loss, enhancing system efficiency by integrating the flow meter directly into the manifold, thus minimizing capacitance and pressure drop.

Abstract

An example flow meter insert includes a housing; a shaft mounted partially within the housing such that the shaft protrudes outside the housing; a turbine that is rotatably coupled to the shaft, wherein the turbine comprises an impeller mounted to the shaft external to the housing; a plurality of magnets, wherein the turbine is configured to rotate as fluid flows across the impeller, thereby causing the plurality of magnets to rotate therewith; and a sensor mounted adjacent the plurality of magnets to detect variation in a magnetic field as the plurality of magnets rotate along with the impeller, wherein, based on detecting the variation, the sensor is configured to provide information indicative of a count of revolutions and direction of rotation of the impeller to facilitate determining fluid flow rate and direction of fluid flow.
