Veeder-Root Sensor Application Guide Hydrostatic Reservoir Sensor The Hydrostatic Reservoir Sensor accurately detects fluid level change in the reservoir and interstice of a double- wall storage tank . This sensor is available in a dual-point or single-point configuration . The DuakPoint version is ideal for high groundwater areas , and can differentiate between a high level alarm conclk tion and a low level alarm condition . If an inner-wall leak occurs , the brine seeps into the tank triggering a low level alarm , if an outer wall leak occurs , fluid seeps into the interstice triggering a high level alarm . The Single- Point version can be used in low groundwater locations. If an inner-wall leak occurs , the brine seeps into the tank triggering a fuel alarm , or if the outer wall leaks , the brine seeps out of the tank interstice triggering a fuel alarm . Sensor Detection Capabilities - Alarm Conditions • DuakPoint Version - Leak in inner wall triggers a low level alarm - Leak in outer wall triggers a high level alarm in high groundwater areas or a low level alarm in low groundwater areas . - An open sensor triggers a sensor out alarm . • Single- Point Version - Leak in inner or outer wall triggers a fuel alarm in low groundwater areas. - An open sensor triggers a sensor out alarm . Operating Capabilities • Operating temperature range : -25 to +50°C. • Storage temperature range : 40 to +60°C. • Operates in salt brine solution of up to 30% CaCI . • Cable length : 12 feet • Sensor dimensions : Single Point - 6" high , 2 .5" diameter ; Dual Point - 17 . 3" high , 2 .5" diameter.
