SENTRY ATO WITH SOLENOID VALVE – INTELLIGENT WATER REFILL SYSTEM

Intelligent ATO system – with very sensitive Optical sensor and solenoid valve included.

Sentry allow to set sound alarms for:
– empty refill container issue
– too high water level in sump

Sentry ATO not allow for overflowing when optical sensor is damaged, disconnected or not properly adjusted. After few refill attempts without successful water level reading by optical sensor – DC pump/solenoid valve is switched off and alarm is on. Using “intelligent” CPU allow for using only one but very precise optical sensor instead of pair – optical and floating.

Each set include:

– Sentry main unit
– optical water level sensor with adjustable holder
– DC pump/Solenoid Valve
– acrylic tubing holder
– power supply(EU/USA/UK/AUS plug)
– manual

The Sentry ATO is available in two different models: one with a silent-running DC pump and another with a solenoid for use with direct connections to RO systems. Both options feature a small control box with a programmable button (for fill and alarm adjustments), an optical water sensor, tubing, and acrylic mounting brackets for all of the aforementioned. The optical sensor is specially designed and reportedly sensitive to 2-3mm water level. Instead of the sensor being pointed vertically down, Pacific Sun design a horizontal optical sensor with a 90 degree prism; This clever design prevents water droplets accumulated at the bottom of sensors from interfering with readings. The sensor reads the water level every 5 seconds; should the water fail to achieve the desired level after 20 read cycles, the Sentry ATO will shut down the pump/solenoid while sounding an alarm to notify the aquarist the top-off reservoir or water supply is dry (or there is another problem). The alarm can also be programed to sound if the water level is too high.
