It features functions such as combined control of upper and lower water tanks, water tank drainage and water shortage protection, which can automatically realize water tank water supply and drainage, effectively preventing overflow due to excessively high water level in the water tank or pump idling damage. Equipped with an AC contactor, a motor protector and phase failure protection internally, it supports multiple wiring methods and can achieve various wiring modes including single-phase single control of the upper water tank, single control of the lower water tank, water shortage protection, and combined control of upper and lower water tanks. During installation and use, it is necessary to check whether the wiring and float switch signals are in good condition; it is recommended to use Elec brand float level switches as supporting products<\/p>","protected":false},"excerpt":{"rendered":"<p>Three-phase Liquid Level Controller (ESF Series) adopts float switch control, featuring multiple protection and control functions.
