Liquid Watch
LiquidWatch® Monitoring Units have been engineered to meet a broad range of customer needs. The system can be configured with up to 64 probes and 16 alarm relays. The modular design allows for meeting current needs while allowing for future expansion of the system.
LiquidWatch® employs a 2 line, 20 character backlit LCD with ap> membrane keypad for operator interface. The probe circuits are supervised and provide alarms for probe active, short and break conditions. Probes can be programmed on a leak alarm to operate one of 16 optional relays for remote alarm indication or operation of a shut down procedure.
LiquidWatch® Monitoring Units are equipped with normally energized 10A, 240 VAC, DPDT relays: 1 common alarm relay and up to 16 programmable relays (in modules of four). The alarm console can be located up to 10,000 feet (3000m) from the probes. The probe modules (8 probes per module) can be mounted remotely to reduce wiring costs. The patented probes for LiquidWatch® are solid-state design and respond in seconds after contact with organic liquids or water. Hydrocarbon fumes or vapors have no effect, thereby virtually eliminating false alarms.
The LiquidWatch® Monitoring Unit can also monitor any switch (float switch, thermostat, high level switch, dry contact, etc.), using the optional probe adapter.
