Levelmatic pilot controllers use a simple, stable, floatless differential pressure sensing principle.
They require only two simple connections to the vessel (open or closed).
Standard units come in two sensing ranges: 0 to 36 inches and 0 to 200 inches (H20).
Normal operating pressure is 10-22 psi.
Static pressure on the sensing diaphragm can be anywhere within the range of 30″ Hg vacuum to 300 psig.
Options include fixed or proportional band.
