Mounting Style
Desk Mount: WiFi LCD Keypad with 2.8" IPS full colour display — ideal for placement on a bench, shelf, or desk inside your home or shed.

Sensor Cable Length
Standard 4 Metre Sensor: Suits most standard residential and rural water tanks. The stainless steel pressure sensor hangs inside the tank to measure water depth accurately.
Extended 10 Metre Sensor: Designed for deeper tanks, underground cisterns, or installations where the sensor needs to reach further into the tank. Ideal for large-capacity storage or buried tanks where a standard 4m cable won’t reach the bottom.
Frequently Asked Questions
How does the system work?
Wireless sensors installed on your tank measure water levels and transmit real-time data via LoRa wireless to the WiFi keypad and your mobile app or cloud platform.
Can I install it myself?
Yes — the SW900 is designed for DIY installation. Connect the sensors to your tank, sync with the app, and you’re done. Full installation instructions are included, and customer support is available if needed.
Which sensor length do I need?
Choose the Standard 4 Metre sensor for most above-ground tanks. If your tank is particularly deep, underground, or the sensor needs to travel a longer distance to reach the water, select the Extended 10 Metre option.
Do I need Wi-Fi?
Yes, a Wi-Fi connection is required for remote monitoring via the app or cloud platform. The system connects to 2.4GHz Wi-Fi networks.
