Fluidy Water Insight Module

Yes. The old gauge doesn't interfere with the new measurement. Many people leave it in as a second display until they trust the new one.

We currently make no promises for that. Urine scale can build up in the urine container, and that makes measuring difficult. In fresh, grey and black water tanks, on the other hand, installation is the same everywhere.

Fluidy Pro keeps an eye on all the water in your camper:

• levels of up to 4 tanks, for example fresh, grey and black water
• up to 5 temperatures, for example at the boiler, in the heating circuit or at the fresh water tank
• the pressure in the water line
• leaks via the leak cable

For smaller builds there is Fluidy, more compact and more affordable. Both fit into the same system.

More on this in Tank levels, temperatures, pressure: what Fluidy Pro measures.

No, Fluidy deliberately comes without sensors, so you only pay for what you really need. Level sensors, temperature sensors, the water pressure sensor and the leak cable are available from us individually. The matching connectors come with each sensor.

Typically to within 1%, relative to the full measuring range. The sensor hangs in the tank and measures how strongly the water presses on it at the bottom. That tells you how full the tank is. Floats or three-stage probes, by contrast, usually only tell you that things will get tight at some point.

The calibration in the dashboard guides you step by step, no maths needed.

Yes. At the very bottom of the tank settings you export the calibration. If you ever delete the tank widget or create it again, you load it back in completely via "Load profile". Best to back it up right after calibrating. Converters use the same calibration for the next vehicle this way.

Installation is the same for fresh, grey and black water tanks. The sensor also measures perfectly in stainless steel tanks, because it hangs inside the tank and does not have to measure through the tank wall.

You need a 17mm hole at the top or side of the tank, close to an inspection opening. The watertight cable gland is included.

Step by step in Installing the water level sensor.

Level sensors and the water pressure sensor must be completely free of water whenever there is a risk of frost. If water freezes inside a sensor, it is permanently damaged. So when you winterise, drain the tanks and empty the fresh water system, ideally draining the pressure sensor via the drain tap.

Yes, they can be connected, but we have not tested this. The two contacts of the cable go to + and S on the leak port, polarity does not matter. Our own leak cable is tested for durability and detection. With third-party cables we do not know the coating or construction, so we cannot guarantee that a leak will be detected reliably, now or in a few years.

With a 3m leak cable that you lay flat wherever a leak would show up first: under the pump and boiler, along the water installation, at the water filter. As soon as the cable gets wet anywhere, the SmartKnob raises an alarm. With the leak widget, the water pump switches off as well when the alarm goes off.

To cover more area, simply connect several leak cables in parallel to the leak port.

More on this in Detecting water leaks: how the leak cable works.

Yes. Join the cables in parallel, for example with WAGO terminals, and run them to Fluidy with a two-core cable.

Yes, they work together with our sensors on Fluidy. Run a short cable from the connector to a distribution point near the sensors and branch off from there. Fluidy recognises each sensor individually, and you name them under Settings, Sensors.

By the way, our own sensors are not DS18B20 but a further development that measures faster and more accurately, with cable and insulation made of food-safe silicone.

Up to 5. They all share one common line, which may be no longer than 3m in total. The sensors measure to within 0.5°C and have a food-safe silicone cable.

Tip: run a short cable from the connector to a small terminal block near the sensors and branch out from there. That is more reliable than clamping all the cables directly into the connector.

More on this in Installing temperature sensors.

It sits in the line behind the fresh water pump and shows you whether the pump is running. Above all, it notices when the pressure keeps dropping, for example because a fitting is leaking and the pump keeps starting. That way a creeping leak is spotted before anything gets wet.

How to install it is explained in Installing the water pressure sensor and leak cable.

Together with the boiler widget, you control your hot water based on the temperature actually inside the tank. And when the fresh water tank runs low, the widget blocks the heating elements so that the boiler never heats dry.

There are two ways: put the sensor into an existing blind hole in the boiler, or tap the temperature at the safety valve with a T-piece and an immersion sleeve. Thermal paste improves the heat transfer from the boiler to the sensor.

Good to know: the sensor does not measure directly in the water. The water in the boiler can be hotter than the reading and can also reach its temperature sooner.

A fill level sensor does not fit in a boiler. It is a closed pressure vessel and always full during operation.

Yes. You set the thresholds, for example fresh water below 20% or grey water above 80%. The SmartKnob lets you know in good time so you can plan your next fill-up and emptying.
