Introduction to Basic Principles
Types of Level Measurement 1.A STICK/SOUNDING TAPE/SITE GLASS 2.MECHANICAL FLOATS 3.CAPACITANCE 4.HYDROSTATIC PRESSURE 5.RADAR/SONAR
Typical Level Sensors
Hydrostatic Pressure PRESSURE-FORCE/AREA Water Column Density and Specific Gravity P=h*SG/27.68 Sensor Ranging
Pressure vs Volume
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
Typical 4-20mA Loop
Remote Indicator Loop
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.
