BF-912A+ is a fully automatic controller for pumping, drainage, and water filling. It automatically controls water supply, provides low-water protection, and is suitable for a wide range of drainage and pumping applications.
Uses microcomputer IC control with staged water level control for upper and lower reservoirs (water towers) in high-rise buildings.Enables automatic refilling of a water tank (water tower) or automatic drainage, as well as joint control of upper and lower reservoirs;Effectively prevents pool overflow caused by excessive water levels and pump damage from dry running; suitable for industrial and household applications.
Ideal for unattended automatic pumping for water towers and wells serving cities, rural areas, schools, industrial and mining enterprises, and households. Also widely used in dyeing, chemical, food, beverage, brewing, sugar-making, and other industries.
★ Fully automatic water supply: stops when the tank is full and starts automatically when water is low.
★ Water-shortage protection prevents pump damage from dry running and heater damage caused by dry firing when the tank is empty.
★ Also convenient for drainage and pumping applications, such as municipal ditches and ponds.
★ Supports coordinated control of dual water tanks (sources), such as pumping from a small tank (source) to a large storage tank.
BF-912A+ offers two mounting methods, DIN-rail and screw-fixed, for easy maintenance.
