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.
Claims17
A sensor assembly for a fluid flowmeter comprising:
- a body having opposing ends and a hollow interior, one of said ends including an opening in communication with said interior, said body configured to have a moisture impermeable barrier that prevents moisture from entering said interior at extreme fluid pressures;
- at least one electrode mounted on said body;
- a coil assembly configured to be removably inserted through said opening and into said hollow interior of said body, said coil assembly including at least one magnetic coil electrically isolated from said at least one electrode when said coil assembly is axially inserted into said hollow interior of said body.
A sensor assembly for a fluid flowmeter comprising:
- a cylindrical body having an outer surface, said body defining a longitudinal axis, a central blind hole and two channels, said two channels being parallel to said longitudinal axis and radially spaced at a designated angle from each other on said outer surface;
- a sensing electrode assembly mounted in one of said two channels;
- a ground electrode assembly mounted in said other of said two channels, at least one of said sensing electrode assembly and said ground electrode assembly including a plurality of spaced electrodes;
- a coil assembly configured to be removably, axially inserted in said central blind hole of said body, said coil assembly including a plurality of magnetic coils, each of said magnetic coils being electrically isolated from and aligned with one of said plurality of electrodes on said sensing electrode assembly when said coil assembly is inserted into said central blind hole of said body.
