It mounts in a 2 inch NPT opening into the interstice and carries a float on a rod assembly. Under normal conditions nothing shows; if product from the primary tank - or water from outside - enters the interstitial space, the float rises and drives a red indicator up into the viewing window, signalling a leak in the double-wall containment system. Only the 2 inch opening version reaches past 76 inches, which is why tall tanks use this gauge. Each gauge is built to the depth of the tank it serves. Newberry supplies these as Krueger Sentry Type K leak detection gauges. Size is based on tank height or diameter, not tank capacity.\u003c\/p\u003e\u003ch6\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterstitial leak detection:\u003c\/strong\u003e Detects liquid in the annular space of a double-wall containment tank.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRed indicator:\u003c\/strong\u003e A red indicator rising into the viewing window signals a leak in the containment system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt for tall tanks:\u003c\/strong\u003e The 2 inch opening version is the only one built past 76 in - it reaches 170 in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-section rod construction:\u003c\/strong\u003e Above 77 in the gauge uses multiple rod sections joined with brass connectors and a 3\/16 in self-align union, assembled at installation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNo power required:\u003c\/strong\u003e Fully mechanical - no wiring, sensors or power at the tank.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eState approvals:\u003c\/strong\u003e Florida DEP EQ 675 and Michigan DEP approved for double-wall containment systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAlarm option:\u003c\/strong\u003e An optional audible alarm can be remote or direct mounted.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount:\u003c\/strong\u003e 2 in NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSizing basis:\u003c\/strong\u003e Based on tank height or diameter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDepth range available:\u003c\/strong\u003e 6 in to 170 in on the 2 in opening\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFloat:\u003c\/strong\u003e HDPE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRods:\u003c\/strong\u003e Aluminum (stainless steel upgrade available)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBushing:\u003c\/strong\u003e Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRod unions:\u003c\/strong\u003e 3\/16 in self-align union with brass connectors (77 in and above)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCalibration material:\u003c\/strong\u003e Plastic (glass upgrade available)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhat it indicates:\u003c\/strong\u003e Liquid in the interstitial space - a leak in the containment system.
