Safe, Reliable, High- & Low-Level Warning & Spill Prevention System for Storage Tanks
The system incorporates Dynamic Self-Checking® circuitry which monitors the controller, wiring, connections, and sensors for faults 30 times per second for maximum safety
Sounds an audible alarm and/or controls pumps and valves for automatic shutdown when the sensors detect liquid or a fault in the system
As a high-level warning and emergency shut-down system, it operates independently from your gauging system to ensure that inventory inaccuracies do not compromise the safety of your operation

The Scully WX System is certified by exida® as SIL3 Capable
The WX System provides for the capability of alarms as well as controlling pumps and valves for immediate, automatic shutdown of product flow
Monitors from 2-12 sensing points depending on mode—well suited for multiple fixed storage tank applications where individual display and/or output control is required
Uses output sensors approved as intrinsically safe for use in Class I, Division 1, Group C, and D hazardous locations
Features NEMA 4 style watertight housings
Works in conjunction with either Scully field-proven thermistor or two-wire optic sensors
