Sensors for Non-Potable Water

Sensors for Non-Potable Water Select Your Product

Waste water and sewage treatment processes produce unending equipment and operator issues. Clogged pumps are caused by debris from cleaning, solids from processing and particles from agitation. Increased difficulty in level sensing occurs as waste water becomes foamy, turbid and more chemical-laden. From holding tanks to pits, ponds, streams, and reservoirs, Madison Company manufactures standard and custom-designed switches and sensors for virtually any waste water sensing application. Each Madison product is designed and manufactured to withstand even the harshest of environments.

Key features of Madison liquid level sensors and float switches for non-potable water include:  

  • Wide variety of chemically resistant materials available – 316 Stainless Steel, Buna-N, brass and PBT
  • Slosh shields on many products to prevent floats from sticking
  • Technology options such as pressure, tilt, ultrasonic and radar level sensors
  • Custom Engineered liquid level solutions for specialized applications.
  • Same day shipment for many liquid level sensors and float switches
  • Personalized service and support
