Crude and product lines, cooling water, hot work avoidance, hazardous areas
On a live refinery or petrochemical unit, cutting into a line is not a maintenance task — it is a hot work permit, a gas test, a fire watch, and a set of approvals. Non-intrusive measurement removes the hot work permit and the leak path from the equation entirely.
Seztec is in Houston, on the Ship Channel's doorstep. Baytown, Pasadena, Deer Park, Texas City, La Porte — and the Beaumont / Port Arthur / Lake Charles corridor beyond. We know what a permit costs you.
Product moves and someone gets billed. When a fiscal or allocation meter's number is disputed, a clamp-on portable is an independent, non-invasive check on a live line — without pulling the meter and without stopping the transfer.
The honest caveat: a single-path clamp-on meter is generally not the instrument for custody transfer itself. It is a superb instrument for checking one. We will tell you which conversation you are having.
Enormous pipes, high uptime, and no appetite for cutting anything. Above roughly 12″, clamp-on economics beat inline decisively — an inline meter on a 36″ cooling water header is a capital project.
Amine, caustic, spent acid, sour water. Nothing wetted means nothing to corrode. The Ultraflux Minisonic Fixed is specified for water, acids, alkalis and chemicals.
If the instrument is going into a classified area (Class I Division 1 or Division 2, or the Zone equivalents), say so before you specify anything. The transducers, the transmitter, the cabling, and the barriers all change — and a standard instrument in a classified area is not a compliance problem you can fix afterwards.
This is not a footnote. It is the first question we should be asking each other, and it is the one most likely to be discovered late. Tell us the classification.
It exists, and it is a considerably more demanding application than liquid — gas is far less acoustically dense, so getting a signal across the pipe is harder and generally needs higher line pressure and purpose-built transducers. Steam is a different problem again. The instruments in this catalog are liquid instruments. If you need clamp-on gas metering, call us and we will route you to the right product rather than sell you the wrong one.
Send us the pipe and the fluid. An application engineer will confirm the right instrument — or tell you clamp-on is the wrong answer, which happens and which we would rather say first.
