AE0000 WLEXC Extra Cable 
Cable length is measured from top of logger to bottom of sensor.  Up to 1000 feet of extra cable can be added at the factory.
AJ1000 THO Titanium Option 
Replace the standard stainless steel water level sensor housing with titanium.

PRPP/PRPM Pressure Pipe Option
Water level sensor is housed in a 8 inch PVC (PRPP) or stainless steel pipe with 3/4 inch NPT male thread (PRPM) for logging pressure in municipal water systems.  10 ft cable standard.  Calibrated in psi with ranges of 0 to 30 psi, 60 psi, 100 psi available.
AG0000 WL-SWO Sewer Flow Option 
Mouse-shaped cover protects sensor from fouling and velocity effects in sewer, stormwater and irrigation pipe flows.  Mouse is attached to 4 inch X 24 inch stainless steel strap for mounting sensor on pipe bottom.
AN0000 WL-T Temperature Output Option 
Range: 0-50° C, Accuracy: 1% of reading, Output: 0-10mA
