Water Float, suitable to signal the lack of liquid inside the tank, is available in all the 30mt. prevalence pumps and in the 11mt. prevalence pump model WASPT.
When connected to an external alarm, managed by the control system, it will advise the operator when the tank is empty and needs to be refilled.
The water float must be correctly positioned inside the tank as specified in the installation manual, so that you can decide at which water level you want to be advised.
Please note that when the water float is in vertical position, which means there is no water inside the tank, it will automatically stop the pump cutting the power to the pump. For this reason, if you are just testing the product, please be sure to position the water float horizontally to simulate the presence of water into the tank, otherwise the pump will never work.
