SSM AquaMax Plastic Manual Water Level Indicator with 5 Levels with 15 m Wire, Standard Size, White

I have installed this product. The sensors are to be fixed at 6 locations vertically in the tank. Hence I bought a 3/4 inch pvc pipe and cut for the height of my tank and fixed these sensors at different levels using the glue gun. 15 meter, 6 core cable is provided by the seller and that is perfect to solder all the sensors and connect to the indicator unit provided by the seller. The performance of the gadget is perfect. The quality of the build is also excellent. Only difficulty the buyer would face is to fix the sensors at different levels in the tank. If you use the method of fixing the sensors on a stand pipe (PVC hollow) and later with a clamp to fix the stand pipe with sensor into the tank it becomes very easy to handle the sensor module. By this you also make sure that you are not drilling the tank at different levels and make it leak. I have drilled for the stand pipe clamp only above the normal water level and hence no possible tank leaks due to the drilling in the tank. There is a buzzer to sound when the water level reaches the top and also when it is at the low level which is very useful. However there is switch on the side of the indicator/controller unit to put off the buzzer if it is annoying. This model does not have switching motor on and off relays and it is only the water level indicator. Product quality and function is excellent needs a little effort needed to fix the sensors only.
