Gardena AquaCount 18350-20 Water Meter
The Gardena AquaCount is a battery-powered water meter that measures the quantity of water flowing through. It helps you control water consumption when watering and dose water as required, for example when fertilising. At the campsite, allotment or at home you can easily see how much water you use every day and over the whole season.
The meter connects directly to the tap or to the end of the hose, in a horizontal or vertical position. The large display can be rotated, so it is easy to read in any position. The button cell battery is included, so the meter is ready to use straight out of the box.
Key features
- One button for all functions: a short press switches between display modes.
- Sum 1 and Sum 2: two independent counters, e.g. for daily and seasonal consumption. Holding the button for 2 s resets the selected counter.
- Auto mode: measures the water used during one watering session. After an interruption longer than 2 s, the next session starts from zero.
- Flow mode: shows the current flow rate in l/min or gal/min.
- Battery indicator: a symbol on the display warns of low battery.
- Durable design: frost-proof, UV-stable and easy to clean.
- Original GARDENA System: suitable for all garden watering devices of the system (except drip irrigation).
