Types of Level Measurement • A STICK/SOUNDING TAPE/SITE GLASS • MECHANICAL FLOATS • CAPACITANCE • HYDROSTATIC PRESSURE • RADAR/SONAR
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.
