Products
Two models. Same Transmitter and Receiver — the difference is the sensor.
FloatMASTER
Simple, reliable HIGH or LOW alarms for septic tanks, cisterns, sump pits and stock tanks.
- 2 float switches included, 20 ft (6 m) cables
- Set each float to alarm when the level is high or low
- Two alarm points, one per float
- Float and alarm history on the dashboard
FloatMASTER PRO
The exact level, all the time — for cisterns, dose tanks, larger tanks and commercial sites.
- Submersible pressure probe (0–5 m), 5 m (16 ft) cable
- Continuous level 0–100% and water depth in cm
- Four alarm points you set
- Tank gauge, sensor diagnostics and remote recalibration
Both include the Free Basic Dashboard for the life of your device. Compare Free and Premium →
What you get
Transmitter — at the tank
OLED display, red and green LEDs, 85 dB buzzer and rechargeable battery backup in an IP65 enclosure. Reports every few seconds on mains power, every 10 minutes on solar.
Receiver — in your building
OLED display, LEDs, 85 dB buzzer, auxiliary relay and battery backup. Runs on the USB-C adapter in the box and connects to your 2.4 GHz WiFi.
Also in the box
Your sensor (2 floats or the PRO probe), mounting hardware, weatherproof cable glands, Quick Start Guide and a registration card with your Device ID.

The PRO dashboard
Desktop
Mobile
Remote recalibration
Reset the sensor’s zero point from the dashboard once the probe is lifted out of the water — no technician.
Sensor height
Probe not on the floor? Enter its height. 100% is full; the lowest reading is the sensor height, since water below the probe can’t be measured.
Live diagnostics
Sensor voltage and a health notice, so a failing probe can’t fail silently.
Cross-device sync
Change a setting on your phone and it confirms on every device.
Settings audit trail
With Premium, every setting change is logged with the time and the old and new values.
Built for cold
Under-load battery monitoring and cold-weather field validation for Canadian winters.
Built into both models
Long-range LoRa
915 MHz radio, up to 500 m in open areas. No WiFi needed between the units.
Local alarms
LEDs and buzzers work with no internet — your primary alarm.
Email and text alerts
Alarms, all-clear, offline and power-loss notices.
Mobile dashboard
Any phone or browser, anywhere. No app to install.
Auxiliary relay
10A @ 250VAC on the Receiver for a beacon, pump or second alarm. A failed sensor always trips it.
Signal diagnostics
Measured signal strength, signal-to-noise and a 24-hour connection timeline.
Paired to your Receiver
Your system ignores a neighbour’s traffic, and theirs can’t change your settings.
Updatable in the field
The Receiver downloads updates itself; the Transmitter updates on site. Nothing to ship back.
Powering the Transmitter
The Receiver runs indoors on the adapter in the box. The Transmitter sits outdoors at the tank and needs 5 V DC — choose one of these.
🔌 Power Kit — $99 · Recommended
Most septic installations already have an alarm circuit at the tank. This puts a weather-resistant USB outlet on it: Leviton USB-C receptacle, extra-duty while-in-use cover and an outdoor-rated USB-C cable.
Wiring by a qualified electrician (not included).
☀️ Solar Kit — $129
For remote cisterns, livestock troughs and seasonal properties with no power at the tank. Matched 12 V panel and voltage regulator, tested for Canadian winters.
Solar units report every 10 minutes to save the battery (PRO: every minute near an alarm point).
An equivalent weatherproof, cold-rated outdoor USB supply also works. Every Transmitter has cold-weather charge protection built in, so you can switch to solar later.
