• Top-up system

A simple system with a single float can connect either a pump or an electromagnetic valve as the actuating device. Its main advantage, in my opinion, is its compactness and ease of installation.

Tell us more about the float contact closure. Materials? Design?

Great! The simpler, the more reliable!!! (and cheaper) Recently, my super-reliable auto top-off with two floats and an alarm broke down and stopped adding water. I didn't even notice how the return pump started sucking in air.

This is probably Tunze???? The more details, the less reliability... There are two components in this - a relay and a float.

I wonder who the manufacturer is and what model it is?

Can I buy a set?

Everything is fine, but: 1) judging by the photos, a float switch is used that directly controls (turns on and off) some pump or valve. Based on the two wires, it seems to be a break - short circuit of the phase or neutral wire. That's not good. It's still 220 volts. 2) if there is a refill, there should be an overflow protection. It is done in exactly the same way. A sensor for the upper position is connected in series with the lower position sensor (float switch). Nothing complicated. In summary: switch the control system to a lower voltage (12 or 24 volts) and add overflow protection. That's my opinion.

1 The float switches not the pump but the relay. The sensor is installed in the wall of the tank, the wires are not in the water. 2 If something malfunctions, it stops refilling, which is not dangerous. Added after 1 minute. It is possible.

Is that how, excuse me? And the sensor design. Industrial?

Lindsay

Yes.

No, I have a homemade one. But it's similar to a TUNZ. My weak point is the sensor connection ports and the quality of the soldering.
