Veeder-Root Sensor Application Guide 15 Hydrostatic Reservoir Sensor The Hydrostat i c Reservo i r Sensor accurately detects flu i d level change i n the reservo i r and i nterst i ce of a double- wall storage tank . Th i s sensor i s ava i lable i n a dual-po i nt or s i ngle-po i nt conf i gurat i on . The Dual-Po i nt vers i on i s i deal for h i gh groundwater areas, and can d i fferent i ate between a h i gh level alarm cond i - t i on and a low level alarm cond i t i on . If an i nner-wall leak occurs, the br i ne seeps i nto the tank tr i gger i ng a low level alarm, i f an outer wall leak occurs, flu i d seeps i nto the i nterst i ce tr i gger i ng a h i gh level alarm . The S i ngle-Po i nt vers i on can be used i n low groundwater locat i ons . If an i nner-wall leak occurs, the br i ne seeps i nto the tank tr i gger i ng a fuel alarm, or i f the outer wall leaks, the br i ne seeps out of the tank i nterst i ce tr i gger i ng a fuel alarm . Sensor Detection Capabilities - Alarm Conditions • Dual-Po i nt Vers i on - Leak i n i nner wall tr i ggers a low level alarm - Leak i n outer wall tr i ggers a h i gh level alarm i n h i gh groundwater areas or a low level alarm i n low groundwater areas . - An open sensor tr i ggers a sensor out alarm . • S i ngle-Po i nt Vers i on - Leak i n i nner or outer wall tr i ggers a fuel alarm i n low groundwater areas . - An open sensor tr i ggers a sensor out alarm . Operating Capabilities • Operat i ng temperature range : -25 to +50°C . • Storage temperature range : -40 to +60°C . • Operates i n salt br i ne solut i on of up to 30% CaCl . • Cable length : 12 feet • Sensor d i mens i ons : S i ngle Po i nt - 6 ” h i gh, 2 . 5 ” d i ameter; Dual Po i nt - 17 . 3 ” h i gh, 2 . 5 ” d i ameter .
