removing fluid which rises above the sensor. The ADDP system is powered by
compressed air and requires no electricity. It is capable of flows from 0 to 15 gallons
per minute (GPM), li ing from 22 feet or less below ground at sea level, and pushing
with a force of 100 psi (231 feet of water column).
