I <br /> EEDER-ROOT TEM#36 <br /> Hydrostatic Sensor <br /> For use with TLS and ILS Systems <br /> Veeder-Root's Hydrostatic Reservoir Sensor accurately detects fluid <br /> level change in the reservoir and interstice of a double-wall storage <br /> tank. Dual-float and single-float technology models are ideal for <br /> locations with high or low water tables. <br /> Available in a dual-float or single-float configuration. The Dual-Float <br /> Hydrostatic Sensor is ideal for high groundwater areas, and can <br /> differentiate between a high level alarm condition and a low level <br /> alarm condition. If an inner-wall leak occurs, the brine solution seeps <br /> into the tank lowering the brine level in the reservoir. The Dual-Float i <br /> Sensor will then trigger a low level alarm. If an outer-wall leak <br /> occurs, the groundwater seeps into the reservoir. The dual-float <br /> sensor will then triggers a high level alarm. <br /> The Single-float sensor is ideal for low groundwater areas, since it only detects low level alarm <br /> conditions. If an inner wall leak occurs, the brine solution seeps into the tank. If an outer-wall leak <br /> occurs, the brine solution leaks out of the tank. In both cases, the brine level decreases and the <br /> Single-Float Sensor triggers a low level alarm. <br /> This product is designed to meet California's requirement for secondary space monitoring for tanks as <br /> required by AB 2481. <br /> Features <br /> Dual-float sensor alarm conditions: <br /> • Leak in inner wall triggers a low level alarm <br /> • Leak in outer wall triggers a high level alarm in high groundwater areas; low level alarm in low <br /> groundwater areas <br /> Single-float sensor alarm conditions: <br /> • Leak in inner or outer wall triggers a low level alarm in low groundwater areas <br /> Temperature Rating <br /> Storage: -40 degrees C to + 70 degrees C <br /> Operating: -25 degrees C to +40 degrees C <br /> Rests in salt brine solution of up to 30% calcium chloride <br /> Cable length: 12 feet Single-Float Sensor Dimensions: 6.0" high, 2.5" diameter <br /> Dual-Float Sensor Dimensions: 19.3" high, 2.5" diameter <br /> • Withstands removal from reservoir several times a year without sensor damage <br /> • Clear plastic housing for visual inspection or float operation <br />
