There are times when too much water can be a problem, just as there are occasions when too little can leave you in trouble. The Velleman Liquid Level Controller is the solution.
With this kit you can build a device which monitors levels to warn you if your water tank is close to overflowing or running dry. It can indicate Low, Middle and High levels; automatically switch a pump to keep the right fluid level; and if the sensor detects a level which is too high or too low (selectable), the relay will operate a bell or other alarm.
