1. A flow measurement system comprising a high-pressure severe application meter, with the high-pressure severe application meter comprising:
a flow tube having a wall, two opposing ends, each end having a threaded connection, a bore and interior surface,
a liner that is mechanically affixed to the interior surface of the flow tube via heat shrink and without adhesives, wherein the liner comprises partially stabilized magnesium zirconia;
wherein there is a portion of the interior surface of the flow tube that is not lined with the liner, said portion is in contact with fluid during operation of the meter, and serves to ground the fluid;
at least one electrode installed in the wall of the flow tube that senses a voltage signal, wherein the at least one electrode is tungsten carbide; and
a fitting on each end of the flow tube, wherein each said fitting is a high pressure hammer union.
