BFKT4 Visual Liquid Level Display Switch Controller Water Level Sensor Controller

Features 1、Adopt AC water measurement technology to effectively prevent probe scaling. 2、The water level sensor can detect and display 4 levels of water levels of 0%, 30%, 50%, 80%, 100%. 3、Manually fill the water to the full water level at any time, convenient to use. 4、5 Levels of full water level, 4 levels of replenishment water level adjustable. 5、One way normally open and normally close contact control water output, two way anti&#8209;dry contact output. Specification Condition: 100% Brand New Item Type: Liquid Level Switch Material: Plastic BF-KT4-AC is suitable for various water level control occasion, such as the roof water tank water level display and control of hotels and dormitory buildings, and the water tower water level display control. 4 levels of water level can be set to control the water tank filling, and the full water level and water replenishment can be set freely. The position value, with the function of water shortage and manual water filling, can control the water shortage of external equipment to prevent dry burning. Three-digit digital water volume percentage display, five-level water column, intuitive display of current water level. Switching power supply designs can make sure that the controller's power supply is still stable, reliable and continuous when it changes between AC80V-240V. Features: 1.
