Liquid Level Relay for Precise Industrial Control Systems | Huilong

"In our greenhouse's irrigation system, this relay controls water pumps based on tank levels. The teach-in function let us set high/low limits in seconds, and the compact design fit into our existing control box. No false triggers from water splashes, even during heavy watering—very reliable for agricultural use."

"For our restaurant's grease trap system, this relay replaced a much more expensive model and works just as well. The float-free design prevents clogs from grease buildup, and the audible alarm alerts us when the tank needs pumping. Easy to install and maintain—perfect for small-scale applications."
