Title: Gregory Pastor: Innovator in Fluid Measurement Technologies

Introduction

Gregory Pastor is a notable inventor based in Massy, France. He has made significant contributions to the field of fluid measurement technologies, holding a total of 2 patents. His work focuses on enhancing the accuracy and efficiency of water quality and pressure measurement devices.

Latest Patents

One of Gregory Pastor's latest patents is a capacitive electrical conductivity sensor integrated into a water meter. This innovative sensor determines water conductivity, which is essential for assessing water quality. The design includes a model of a capacitor, a flow of water, and a plastic conduit that facilitates the water flow through the meter. The model incorporates a circuit with a constant phase element connected to a resistor and a capacitor in parallel. By applying an input signal over a range of frequencies, the current flow can identify values of Q and alpha of the model's constant phase element. Ultimately, the conductivity of the water flow can be derived from these measurements.

Another significant patent is a pressure sensor embedded in a metering device. This device features a pipe with upstream and downstream connectors for transducers that measure fluid flow. The conduit is partially made of a resiliently deformable material. A deformable electrode of a capacitor is mounted on the dry-side surface of this material, while the wet-side surface forms part of the fluid flow pathway. Changes in fluid pressure alter the location and shape of the deformable electrode, allowing a circuit to determine the fluid pressure based on the capacitance between the electrodes.
