EDI can customize any of its through-wall references or design special products to meet the unique requirements of a particular application. These products are designated as Model FX followed by a sequence number. Contact us for additional information on any of these products.
| FX01 | Model FS standard reference with varying extensions. These are used where a shallow protruding reference is required such as measuring the potential inside a pipe with the reference located in a tee fitting. |
| FX02 | Model FX02 is a through-wall reference with a fully threaded body (1 inch-8 NC thread). It is designed for installation on a cast iron waterbox that cannot have threaded adapters welded to it. |
| FX03 | Model FX03 is designed to be flush mounted on the wall of a large diameter water tunnel. Dimensions are sized to suit the box recess. |
| FX04 | Model FX04 is a variant of Model FX01A. The flat membrane has been replaced with a hemispherical one so it can be used with potential wheels. |
| FX05 | Model FX05 is a variant of Model FX01A. The flat membrane has been replaced with a ¼ inch dia luggin capillary for measuring potentials behind steel sheet piling. |
| FX06 | Model FX06 is a variant of Model FH. The 1 inch NPT stainless steel nipple has been replaced with swaged steel nipple: ¾ inch NPT on the vessel end and 1 inch NPT on the termination end. |
| FX07 | Model FX07 is a variant of Model FE-BDG. It is designed to mate with a Cosasco RBS Retriever so that potential measurements may be made inside a pressure chamber with a reference located outside the chamber. |
