Veeder-Root Sensor Application Guide Single -Point Mini Hydrostatic Sensor for Double Wall Sumps The Single -Point Mini Hydrostatic sensor accurately detects fluid level change in the interstice reservoir of a dou- ble-wall sump. If a leak occurs in the sump interstice, the brine seeps out of the reservoir triggering a low level alarm. FA% uya Ate,. ry, nim 1' Sensor Detection Capabilities - Alarm Conditionsti� x • A leak in the inner or outer sump wall triggers a Fuel alarm. • An open sensor triggers a Sensor Out alarm. Operating Capabilities • Operating temperature Range: -25°C to +50°C.
