Separate

Coating: No coating

(for meter sizes 1” to 4” (25 to 100 mm)), Phthalic acid resin coating, pearl-gray colored

(standard for meter size 1/2”, 6”, 8” (15,150, 200mm))

Structure: IP67 and NEMA 4X Watertight ( Standard )

Cable connection port: 3/4-14NPT male screw for both signal cable and exciting cable

Cable length: Allowable cable length between the converter and the detector varies with the electrical conductivity of fluid. See Figure 9.1
