Weir. There are many designs of weir, but commonly water flows freely over the top of the weir crest before cascading down to a lower level. A weir / w ɪər / or low head dam is a barrier across the width of a river that alters the flow characteristics of water and usually results in a change in the height of the river level. There are two main types of weir skimmer, those that require the weir height to be manually adjusted and those where the weir height is automatic or self-adjusting.

Water is drawn into the skimmer which moves over the skimmer flap (weir). The skimmer flap (weir) adjusts its self automatically according to the pool water level and suction of the water. These affordable, high-capacity skimmers can skim any oil that will float and flow over the weir. Oil Drum Skimmers feature the use of a rotating drum. These include co-current, counter-current, venturi-style, and ETS skimmers. These affordable, high-capacity skimmers can skim any oil that will float and flow over the weir.

A skimmer will draw in water just fine without a weir door, but it won't skim debris off the surface any where near as well. A weir / w ɪər / or low head dam is a barrier across the width of a river that alters the flow characteristics of water and usually results in a change in the height of the river level. Water flows over the top of a weir, although some weirs have sluice gates which release water at a level below the top of the weir. Each works in a slightly different manner. The weir has a dual function of preventing excessively debris from clogging the skimmer and acts is a backflow control; preventing water from escaping the skimmer compartment once it enters.

The depth of the cut can be adjusted by varying the pumping rate. The weir has a dual function of preventing excess debris from getting in and cloggy the skimmer itself, and prevents water from escaping the skimmers compartment once it’s there. Generally, a floating pool weir can raise and lower its level according to the water level in a spa or pool. Skimmers work best when located on the "downwind" side of the pool; the wind helps push debris toward its opening. Skimmers always contain some type of trapping system to catch the debris as it passes through. Water pours over a floating weir that allows debris to enter.
