Product Details
BF-DKT4 is suitable for various water-level control applications, such as rooftop tank water-level display and control in hotels and dormitories, and water-tower level display and control.
Four selectable water levels control tank refilling; a BESFUL AT35-7-U6 water level sensor measures the tank level;Full and refill levels are freely configurable to control low-water refilling; the output can be manually activated at any time, with low-water dry-fire protection.
A three-digit digital water volume percentage display and five-level water column provide an intuitive indication of the current water level.
The wide-range power supply automatically adapts to AC80V–240V for stable, reliable, long-term operation.
