Embodiment Construction

[0023] When used in conjunction with an electrical signal converter, this sensor assembly is a flow meter used to accurately measure flow through a pipe or open channel and prevent moisture from entering the assembly.

[0024] see Figures 1 to 9 , the present sensor assembly 10 includes an elongated cylindrical sensor body 12 made of a moisture impermeable material such as metal, having a longitudinal axis 14 and forming a hollow interior 16 . In the depicted embodiment, body 12 is cylindrical and has a generally circular cross-section. It is also contemplated that the body may have other suitable shaped cross-sections. Also, in this embodiment, the metal sensor body 12 is made of stainless steel, but could be made of any suitable moisture impermeable material or combination of such materials. The body 12 forms a plurality of channels 18 extending along the length of the body parallel to the longitudinal axis 14 . It should be understood that the body may form one or more ...

Abstract

A sensor assembly for a fluid flowmeter including a body having a hollow interior where the body is configured to have a moisture impermeable barrier that prevents moisture from entering the interior at extreme fluid pressures. The assembly includes at least one electrode that is mounted on the body and a coil assembly configured to be removably inserted in the hollow interior of the body, where the coil assembly includes at least one magnetic coil electrically isolated from the at least one electrode when the coil assembly is inserted into the hollow interior of the body.

Description

technical field [0001] The present invention relates generally to magnetic flow meters, and more particularly to a magnetic flow meter having a sensor assembly that forms a moisture barrier while providing accurate flow measurement. Background technique [0002] Magnetic flow meters are used to measure the flow of conductive fluids such as water through pipes or pipes. This type of flow meter uses Faraday's law to measure the flow rate, or velocity, of a fluid moving through a pipe. Faraday's law states that a conductor moving through a magnetic field produces a voltage. For example, water is a conductor, so when water passes through a magnetic field it generates a voltage. The magnitude of the voltage is directly proportional to the speed at which the fluid (ie, water) moves through the magnetic field. [0003] A traditional flow meter consists of electromagnetic coils inside the sensor that create magnetic fields and electrodes on the sensor that measure the voltage gen...
