One control unit tracks remaining resource on every cartridge in a filter system, calculated from real water usage, and flags temperature, pressure, or salinity conditions that damage filters before anyone notices.
Talk to us about a pilot
The control unit pairs a color display and a rotary encoder with a wireless sensor block over a 2.4GHz link, so the readout sits on the counter while the sensor stays inline with the plumbing. It tracks remaining resource per cartridge, calculated from real flow statistics and each cartridge’s rated capacity in liters rather than a fixed replacement calendar, and works across cartridge models from multiple vendors.
The hardware has gone through four generations: a two-board transmitter/receiver pair, two single-board redesigns, and a color-display revision now getting a full firmware rewrite. Years of real usage logs back the resource calculations.
Cartridges get replaced by guesswork, not by how much water actually passed through them
Each cartridge has a rated capacity in liters. We calculate water actually processed from flow statistics and the install date, then flag replacement when the liter budget or the vendor’s shelf life runs out, whichever comes first.
Multi-filter systems make it hard to track more than one cartridge's resource at once
The control unit tracks every installed filter’s resource independently and shows all of them on one screen, so a reverse-osmosis stage and a carbon pre-filter don’t get replaced on the same schedule just because that’s easier to remember.
A temperature swing can damage a membrane before anyone notices
The sensor block reports water temperature continuously. Five consecutive readings above 38°C or below 3°C trigger an alert that the membrane may already be damaged, instead of finding out at the next scheduled inspection.
A dry feed line or a pressure spike can go undetected until the tap runs dry or the filter fails
Feed pressure under roughly 0.3–0.5 bar reads as no incoming water; above 12 bar reads as dangerously high. Both trigger an alert instead of silent equipment damage.
High-salinity feed water shortens a membrane’s life with no visible symptom until performance already dropped
A TDS sensor on the feed line tracks salinity. A daily average above 850 ppm flags reduced membrane service life before performance actually drops.
Four hardware generations and years of real usage data back this. We’re looking for a manufacturing partner or an early customer to take it from working prototype to a production run.
