A high quality liquid level controller, tested and working, video available.
Three available, this advert is for one item - with an emailed copy of the instructions (as shown in this advert). One unit (for sale here) was wired up for test purposes a few years ago, (the grommets were pierced for cables) the other two are unused and will be listed separately. All three have now been tested and with correct operation confirmed.
These units are used typically to control a pump (240 or 415V or other) or other device depending on the levels of water or other conductive liquid in a tank switching the pump on/off the replenish the level, for example.
Useful for flood defence pumps, ponds and many other applications where water level control or simply level sensing is required.
The controller may be sited up to 500M away from the electrodes according to the instruction sheet.
Powered from 240VAC mains. The changeover relay contacts (rated 240VAC at 5 amp) are volt free and whilst they are generally used for 240VAC switching, they could be used for other separate circuits.
The voltage at the electrodes is 9VAC and ideally stainless steel electrodes should be used. But copper seems to work fine.
This sale is for ONE UNIT as described above.The unit is tested, working and with video available in case of dispute! House and workshop clearance!! £20.
