Hydrostatic Pressure
• PRESSURE-FORCE/AREA• Water Column• Density and Specific
Gravity• P=h*SG/27.68• Sensor Ranging

Pressure is a
function of height
Volume is a function of shape

4-20mA Basics
• Can be run long distances with minimal loss ~1,000 ft+
• Varying impedance or supply voltage will not affect the signal.
• Low electromagnetic susceptibility• Only requires 2 wires to operate

KING Filters
• Single stage or dual stage• Main Line or Point of use• Polisher Selection• Scrubber Selection

Coalescing Filtration
• Compressed air enters• Travels through filter media• Oil and water attach to
fibers• Grow into droplets and fall
off into bowl• Replace elements yearly or
as needed

King’s Outside to Inside Flow
• More surface area for particulate
• Nozzle shaped outlet for better discharge

Removing Oil/Water Vapor
• Using desiccants to remove vapor through adsorption

Desiccant Dryers
• Compressed air passes through an adsorbent media (desiccant) such as activated charcoal, silica gel, or molecular sieve.
