Level Sensors  from Prime Controls Co.  Ametek B/W Controls, Babbitt International Inc.

B/W Controls, now part of Ametek Automation and Process Technologies, has manufactured liquid level controls for the water and wastewater industry since the 1930's. Their sensing relays pass a small current through the liquid to sense the level. They still make the electro-mechanical sensing relay, a direct replacement for discontinued Warrick relays.

Babbitt International has manufactured RF Level controls since 1986. They can measure virtually any liquid, dry material or interface and for standard LS products give a money-back "performance guarantee" for pre-approved applications.

Several of the most common items are normally in stock at Prime Controls Company. Call us for more information, for quotes or to order.
