Why does the 4-20 mA output vary rapidly on TechnipFMC 4728 Measuring Instruments?
- S
  Susan KellyAug 5, 2025
  If the 4-20 mA output varies rapidly while the water cut is steady in your TechnipFMC Measuring Instruments, it might be due to heavy electrical static in the air being picked up by the 4-20 mA wiring. To resolve this, use shielded twisted pair wire for the 4-20 mA signal from the 4728 Unit to the external readout. Ground the shield at the 4728 Unit only, and do not ground the shield at both ends of the wire.

What to do if readings fluctuate wildly during flow in TechnipFMC 4728?

  If your TechnipFMC Measuring Instruments readings fluctuate wildly during flow through the probe but are steady during no flow, and a shake out shows a steady amount of water, it could be due to: * Gas in oil caused by having the probe downstream of a vessel dump valve. * Restricted suction to the charge pump on the L.A.C.T. unit, resulting in cavitation and gas break out. * A loose inner electrode probe.

Why does the output gradually increase in TechnipFMC 4728 Measuring Instruments?
- B
  Brandon Carter MDAug 17, 2025
  If the output of your TechnipFMC Measuring Instruments gradually increases over time, while the water cut remains relatively consistent, it's typically caused by a buildup in the probe, such as paraffin, or a film being deposited by flow line chemicals. The solution involves eliminating the causes of coating buildup or periodically cleaning the probe, potentially replacing the probe's Teflon insulators.

What to do if there is no output from 4528 detector in TechnipFMC 4728?
- A
  Angelica GrahamAug 22, 2025
  If there is no output from the 4528 detector with the probe full of oil in your TechnipFMC Measuring Instruments, it could be due to no power or the probe wire not being attached to the probe stud, or the 4528 Detector Card may be bad. In either case, replace the card.

  If there are no readings or LED lights on the 4728 unit of your TechnipFMC Measuring Instruments, it may be due to no power being applied or a blown fuse.
