We have been using electric level controllers that utilize a SPDT dry contact electric switch, with limited success. The switch is activated by a displacer at the fluid interface. We believe the switch itself is not adequate for our application.
We have recently begun testing another displacer-type electric level controller that utilizes NAMUR sensors. So far this has been effective, but we are worried about the impact of buildup in the nipple area of the displacer arm.
Our fluid properties are as follows:
- Produced water: 1 < SG < 1.2
- Oil: mean SG is 0.75
- Gas: Primarily methane (> 85%)
- We have considerable iron sulfide buildup along with sand production
Does anyone have experience with electric level controllers in a similar environment? Does anyone have experience with Guided Wave Radar or some other type of level measurement device that does not have any moving parts?
All general advice and input is also much appreciated.
Thank you in advance.
