Low level float switch enables sensing in air conditioner drip pans and other shallow level applications

Drip Pan

Standard float switches require at least an inch of liquid to attain enough buoyancy to switch. This can be a problem in applications where low level sensing is required. The hat-shaped design of W.E. Anderson’s Model F7-LL provides necessary buoyancy for switching in only 5/8" of water. This is essential for air conditioner drip pans, low level sumps, and drains. The F7-LL is also ideal for low alarms, where running the process dry can result in catastrophic failure.
