The Welker MLD-1 Manual Liquid Dump is designed to protect downstream instrumentation from damage and contamination by separating free liquids from a wet gas stream. Gas flows freely through the MLD-1, but any aerosols or free liquids are separated from the stream as they pass through the internal coalescer. Gravity causes the separated liquids to fall to the bottom of the MLD-1, where they collect until drained by an operator.
