What to do if TechnipFMC Measuring Instruments show underdelivery or over registration?
- KkathrynwilliamsAug 5, 2025
If your TechnipFMC Measuring Instruments are showing underdelivery (or over registration), it might be due to deposits like wax. Try cleaning the affected parts. Another cause could be clogging of tube bundles, in which case you should remove and clean them. Bent blades can also cause this issue, so replace the rotor if necessary. Cavitation can also lead to underdelivery, so ensure higher back pressure. Entrained air or gas might be the culprit, so eliminate the source or add an air eliminator. Lastly, noise on the transmission line can cause this, so add or check the shielded cable, eliminate the source of noise, ensure the shield is grounded at the instrument end only, decrease sensitivity on the instrument front end, or add a suppression circuit to the preamplifier.
