Norriseal has been a leader in providing quality level measurement devices to the petroleum market for over five decades. In addition to oil and gas applications. Norriseal level control products serve in marine, steel and industrial markets.
Features
No-bleed pilots. The pneumatic controller is equipped with one of three types of no-bleed pilots: a snap pilot, throttling pilot, or patented Envirosave™ pilot.
Removable door. The controller door can only be removed after opening 90°. This feature prevents the door from vibrating loose while in the closed position. A lever latch keeps a positive engagement between the case and the door.
Weather-resistant sealed case (1001A & 1001XL). An O-ring gasket seals internals from outside weather and allows the harmful exhaust gases to be vented to a remote area by tubing the vent connection to an exhaust manifold (when equipped with piped exhaust
option).
Built-In filter. A built-in 40-micron stainless steel filter in the gas supply connection reduces required maintenance of the controller’s pilot.
Specific gravities. The switch can operate with multiple specific gravities in interface or top-level applications.
Min SG available = 0.15
Max SG available = 1.20
Marine service. Stainless steel internals are available. Field-reversible action. This adjustment determines whether rising liquid level will increase or decrease pilot output.
Right- or left-hand mount (1001 & 1001A). The controller may be changed for right-hand or left-hand mount in the field without additional parts.
Electric controller. This option utilizes a standard electric switch; SPDT or DPDT.
Split displacer. For liquid dump spans greater than the standard displacers can provide, a split displacer can give dump spans up to 70 feet in length.
NACE. All controllers can be configured to meet NACE MR0175-2002 specifications.
