Product Details
BF-KT4 is suitable for various water-level control applications, such as rooftop tank water-level display and control in hotels and dormitories, water-tower level display and control, and municipal well-water pumping control.
Gear 4 water level control water tank can be set;Full water level and recharge water level can be freely set by the user;Low-water dry-heating protection output is activated when the water level falls below 30%.
A three-digit digital water volume percentage display and five-level water column provide an intuitive indication of the current water level.Supports water supply at low level or pumping at full level, with manual water supply control.
The wide-range power supply automatically adapts to AC80V–240V for stable, reliable, long-term operation.
