Press the button and a 6 W solenoid opens. A magnet-mounted optical sensor closes it the moment the reservoir reaches level, and an alarm tells you the fill is finished. A second failsafe sensor sits above the first, so an overfill is still caught if the primary sensor is fouled. It replaces the mechanical float valve on a storage container with a part that has nothing in the water to seize.\u003c\/p\u003e\n\n\u003ch3\u003eWhy not just use a float valve\u003c\/h3\u003e\n\u003cp\u003eA mechanical float valve has an arm, a seat and a seal, all sitting in water.

Level is read optically, and the only mechanism is a solenoid on the dry side of the line.\u003c\/p\u003e\n\u003cp\u003eThe optical sensor also fits containers a float valve cannot. It magnet-mounts to the outside of the drum, so there is no lid to drill and no bracket to fabricate, and you change the fill level simply by moving the sensor up or down.\u003c\/p\u003e\n\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOne-button fill\u003c\/strong\u003e — no programming, no timer to set and nothing to recalculate when you change reservoir.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual optical sensor\u003c\/strong\u003e — the second sensor is a failsafe, catching an overfill if the primary level sensor fails.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAudible alarm on completion\u003c\/strong\u003e — you know the fill has finished without standing over it.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNo moving parts to rust or clog\u003c\/strong\u003e — AutoAqua's stated advantage over a mechanical float valve.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMagnetic mounting\u003c\/strong\u003e — no drilling, and the fill level is set by where you stick the sensor.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e12 V DC at the reservoir\u003c\/strong\u003e — the universal adaptor keeps mains voltage away from the water entirely.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuarter-inch push-connect solenoid\u003c\/strong\u003e — the same tubing standard as the RO unit feeding it.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eController supply\u003c\/th\u003e\n\u003ctd\u003e100 to 240 V AC, 50\/60 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAdaptor output\u003c\/th\u003e\n\u003ctd\u003e12 V DC, 1 A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSolenoid valve power\u003c\/th\u003e\n\u003ctd\u003e6 W at 12 V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSolenoid working pressure\u003c\/th\u003e\n\u003ctd\u003e0.02 to 0.7 MPa (0.2 to 7 bar)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWater connection\u003c\/th\u003e\n\u003ctd\u003eQuarter-inch push-connect RO tubing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eLevel sensing\u003c\/th\u003e\n\u003ctd\u003eDual optical sensor, magnetic mounting\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaximum sensor mounting thickness\u003c\/th\u003e\n\u003ctd\u003e12.7 mm (half an inch)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaximum tubing holder mounting thickness\u003c\/th\u003e\n\u003ctd\u003e30.5 mm (1.2 in)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMains adaptor cord\u003c\/th\u003e\n\u003ctd\u003e180 cm (6 ft)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eController to solenoid valve lead\u003c\/th\u003e\n\u003ctd\u003e120 cm (4 ft)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eController to sensor cable\u003c\/th\u003e\n\u003ctd\u003e300 cm (10 ft)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eManufacturer part number\u003c\/th\u003e\n\u003ctd\u003eSASO-200V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\n\u003ch3\u003eWill it reach, and will it mount?\u003c\/h3\u003e\n\u003cp\u003eThree cable lengths and two mounting thicknesses decide the layout, and they are worth measuring against your setup before anything is cut.\u003c\/p\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eConnection\u003c\/th\u003e\n\u003cth\u003eLength\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eMains adaptor cord\u003c\/td\u003e\n\u003ctd\u003e180 cm (6 ft)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eController to solenoid valve\u003c\/td\u003e\n\u003ctd\u003e120 cm (4 ft)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eController to optical sensor\u003c\/td\u003e\n\u003ctd\u003e300 cm (10 ft)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003ePart\u003c\/th\u003e\n\u003cth\u003eMaximum mounting thickness\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eOptical level sensor (magnetic)\u003c\/td\u003e\n\u003ctd\u003e12.7 mm (half an inch)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRO tubing holder\u003c\/td\u003e\n\u003ctd\u003e30.5 mm (1.2 in)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003eThe short leg is the 120 cm between controller and solenoid valve.
