B/W 1500 series relays provide versatile and reliable liquid level control without the use of floats.

B/W 1500 series relays provide versatile and reliable liquid level control without the use of floats. Depending on the contact configuration, they can be used for pump-up (fill) control, pump down control, high level, and low level detection. Liquid levels are established by mounting or suspending electrodes in the tank or vessel. Our customers report that when properly installed and maintained, these relays often provide 20+ years of service. 

Common applications include:

  • Pump-up (fill) control for elevated tanks
  • Make-up water control for boiler systems
  • Pump-down control for sewage and sump pumps
  • High and low level alarms
  • High and low level cutoff
With contacts rated for up to 1 HP, these relays can directly control solenoid valves or small well pumps.
Contact Ratings:
  • 25 Amp resistive at 120, 240, or 480 VAC
  • 1HP single phase at 120 or 240 VAC
  • Heavy duty pilot 120 to 600 VAC
  • 2 Amp resistive at 120 VDC
  • 10 Amp resistive at 48 VDC
Recommended Secondary Coils for Various Liquid Types
Secondary Coil Voltage Typical Liquids
12 Metallic Circuits
24 Metallic Circuits
40 Acid or caustic solutions, Milk, Brine and salt solutions, Plating solutions, Buttermilk, Soups
90 Weak acid or caustic solutions, Beer, Baby foods, Fruit juices
220 Sewage, Most water - except very soft, Pottery slip, Water soluble oil solutions, Starch solutions
360 Soft water, Sugar syrup
480 Steam condensate, Strong alcohol solutions
800 Demineralized or distilled water (5200 Series solid state relays may be better for these applications)

We usually recommend 360 V (S8) secondary coils for fresh water applications unless the water is known to have some dissolved mineral content. For hard water and wastewater we recommend 220 V (S7) secondary coils.
Our most popular relay is the 1500-G-L1-S8-OC-X for its versatility. It can be used for pump-up or pump-down applications in almost any water. The second most popular is 1500-G-L1-S7-OC-X, which is similar but for slightly harder water or wastewater.

B/W 1500 series control relays can only be used to sense conductive liquids. They are not suitable for oil, gasoline, animal fats, and other similar materials, and should not be used with flammable liquids. Electrodes are sold separately. Users should consult Ametek B/W Controls documentation for detailed application information prior to purchasing or installing this item.

For more infomation, please see the Ametek B/W Controls catalog.
