SPECIFIC GRAVITY COMPENSATING.
Featuring continuously adjustable float buoyancy control to allow use in fluids with specific gravity down to 0.6.
Continuous buoyancy control allows switch activation at oil/water interface.
May be used in hazardous areas when used with intrinsically safe relays.
Consult factory for other dual-component fluid interface systems.
Horizontal Mounting Only
Water/Oil Interface switch point
Foam/Fluid interface switch point
High/Low Liquid Level Alarm
Liquid level indication
Direct pump control
Solenoid Valve On/Off Control
Available with Optional Filter Boot For Use in Highly Particle Contaminated Liquids.
Super-simple maintenance and checkout for personnel using a standard test meter.
