Keg Sentry Basic Design
Keg Sentry is a Wired System: Wireless networks represent a significant security risk and many physical and electrical interference problems. The cables used to connect Keg Sentry's modules are standard Ethernet and Rj11 telephone cables. These cables were chosen because they are currently used throughout bars and restaurants, therefore, no special installation skill will be required.
Multiple Eight-Tap Consoles will be installed in bars with more than Eight Taps. A single power supply will be used and power will be daisy-chained to the additional consoles.
12 Volt DC Power Supply
The Flow-Sensor Aggregator is a small module that is installed in a cooler and connects to an Eight-Tap Monitor Console using a standard Ethernet cable. Eight flow sensors are then connected to the Aggregator using a standard RJ11 telephone wire.
Keg Sentry uses highly accurate and repeatable Digmesa Flow-Sensors as a source for flow-rate data. A Flow-Sensor is installed in the beer line and sends digital pulses to its Monitor Module proportional to the amount of beer flowing from its keg. For example, 114 pulses of a US pint of beer.
Flow Sensor Aggregator
Keg Sentry is powered by a highly reliable, telecommunications grade 12 Volt DC Battery Supply and Charger that powers the system for over 20 hours in the event of a commercial Power outage. Batteries usually last two to three years, are readily available, and can be changed while in service.
