Magmeter and method of assembly
The present invention relates to magnetic flowmeters. More particularly, the present invention relates to a magnetic flowmeter specifically designed for the hydraulic fracturing industry that is capable of withstanding a variety of corrosive slurries, acids, bases, and solvents including a liner including partially stabilized magnesium zirconia (MgPSZ).
1 . A flow measurement system comprising:
a primary and a secondary,
with the primary comprising:
a flow tube or pipe having two opposing ends, one or more electrodes comprising stainless steel, and integrated with a magnetic system,
wherein the flow tube or pipe is at least partially lined with liner having corrosion resistance and comprising partially stabilized magnesium zirconia (MgPSZ) material;
wherein the liner is mechanically affixed to the flow tube or pipe via heat shrink and without use of adhesives;
with the secondary comprising a power supply with a synchronized measurement circuitry; and
wherein the primary is tolerant of or configurable to electrical properties of the secondary and operably mates with the secondary.
2 . The system of claim 1 , wherein the liner further comprises an abrasion resistant ceramic trim.
3 . A method of measuring flow using the system of claim 1 .
4 . The system of claim 1 , wherein the system meets requirements for operation in Hazardous areas designated as Class I Division 2.
5 . The system of claim 1 , wherein the primary further comprises a grooved end fitting at each end of the flow tube or pipe.
6 . The system of claim 1 , wherein the primary further comprises a flange at each end of the flow tube or pipe.
7 . The system of claim 1 , wherein the flow tube or pipe comprises metal.
8 . The system of claim 1 , wherein the flow tube or pipe is coated with epoxy.
9 . A magnetic flowmeter comprising:
a. a pipe or tube having an exterior surface and an interior surface, wherein the pipe or tube is at least partially lined on the interior surface with a liner comprising partially stabilized magnesium zirconia (MgPSZ), wherein the liner is mechanically affixed to the pipe or tube via heat shrink and without use of adhesives;
b. at least one coil for generating a magnetic field affixed to the exterior surface of the pipe or tube and having an electrical connection;
c. one or more electrodes having wiring and affixed to the pipe or tube;
d. a shell enclosure, having a tubular neck protrusion, that surrounds the exterior of said coil and is affixed to said coil; and
e, wherein the electrical connection of said coil and the wiring of the one or more electrodes are threaded through the neck of said shell and connected to a junction box having a circuit board for operation.
10 . The magnetic flowmeter of claim 9 , wherein at least one or the electrodes is made of industrial grade tungsten carbide.
11 . A flow measurement system comprising the flowmeter of claim 10 and a secondary, wherein the secondary comprises a power supply with a synchronized measurement circuitry; and wherein the magnetic flowmeter is tolerant of or configurable to electrical properties of the secondary and operably mates with the secondary.
12 . A method of measuring flow using the system of claim 11 .
13 . The magnetic flowmeter of claim 9 , wherein at least one or the electrodes comprises stainless steel.
14 . A flow measurement system comprising the flowmeter of claim 13 and a secondary, wherein the secondary comprises a power supply with a synchronized measurement circuitry; and wherein the magnetic flowmeter is tolerant of or configurable to electrical properties of the secondary and operably mates with the secondary.
