Harwil L-8 Specific Gravity Compensating Level Switch
Finds the interface, not just the level.
The Harwil L-8 features continuously adjustable float buoyancy control, so it works in fluids with specific gravity down to 0.6. That same adjustment lets it switch at an oil and water interface rather than only at a plain liquid level.

What does specific gravity compensating mean?
Float buoyancy is continuously adjustable, so the switch can be set for fluids with specific gravity down to 0.6, and can be set to trigger at an oil and water interface.
Can it mount vertically?
No. The L-8 is horizontal mounting only.
