  • Sensus Regulator  441-57S : 2″, 3″, 4″, 5″, 6″

    Sensus Regulator 441-57S : 2″, 3″, 4″, 5″, 6″

    Available Sizes
    2″, 3″, 4″, 5″, 6″

    The heart of the Model 441-57S is the “Roll-Out” diaphragm. The 441-57S is a spring regulator with performance which approximates that of a pilot operated regulator. The “Roll-out” Diaphragm makes this exceptional performance possible because its action reduces “droop” to a minimum (“droop” being fall off in outlet pressure as a spring regulator opens to increase
    flow.)
    The action of the “Roll-Out” diaphragm differs from that of the conventional diaphragm in the manner in which the change in effective area occurs. Where the effective area of a conventional diaphragm would increase as the regulator opens, the “Roll-Out” area decreases. Conversely, where the area of the conventional diaphragm decreases during closing, the “Roll- Out” area increases. The compressive force of the spring works to open the regulator and is balanced by the opposing force of outlet pressure on the diaphragm which provides the closing force.
    As the regulator opens, the compressive force of the spring decreases. However, as this spring force decreases, there must be a

    corresponding decrease in the opposing force from the diaphragm. For this opposing diaphragm force to decrease, either the effective area or the outlet pressure must decrease. Herein is the essential difference; with a conventional diaphragm the outlet pressure must decrease, where as with the “Roll-Out” diaphragm it is the effective area that decreases, permitting the
    outlet pressure to remain constant.
    The operation actually is quite simple, yet the action of the “Roll- Out” diaphragm is so effective that “droop” is practically eliminated. The Model 441-57S provides constant pressure regulation not previously possible in a “pounds to pounds” spring regulator. It approaches pilot performance, and, in addition, offers the further advantages of simplicity, dependability, freedom from freeze-up, and exceptionally fast response.

  • Sensus Regulator  441-X57 : 2″, 3″, 4″, 5″, 6″

    Sensus Regulator 441-X57 : 2″, 3″, 4″, 5″, 6″

    Available Sizes
    2″, 3″, 4″, 5″, 6″

    The 441-X57 is unique in a high pressure regulator. It features the same “Roll-Out” diaphragm principle that has achieved such remarkable success in the widely used 441-57S and 461-57S Regulators.

    The 441-X57 offers pilot performance with spring regulator simplicity. The “Roll-Out” diaphragm makes this outstanding performance possible by eliminating that old gremlin– “Droop.” “Droop” means rough regulation, wide fluctuation in pressure control as flow varies. It is the result of spring effect plus diaphragm effect.

    The “Roll-Out” diaphragm changes this. By eliminating diaphragm effect and neutralizing spring effect, “droop” is reduced to insignificance. The result–smooth, constant pressure regulation. It comes amazingly close to the control performance of the pilot operated regulator.

  • SONIX Product Line

    SONIX Product Line

    Sonix is nothing short of a transformation in gas metering. Unlike mechanical diaphragm meters, the Sonix digital design completely eliminates moving parts, relying instead on the proven technology of ultrasonics to measure gas flow.
    The digital design provides a host of additional advantages. It creates a platform for extensive diagnostic capabilities and highly accurate temperature correction. Its compact size drastically reduces installation and labor costs and space requirements. A true expression of the principle that “less is more,” Sonix’s compact size and simple, no-moving parts design offers unprecedented levels of accuracy, reliability, and performance available in no other gas meter, all backed by a full 15 year warranty – the best in the industry.

  • Sensus Turbine Product Line

    Sensus Turbine Product Line

    Invensys Energy Metering 2˝ and 3˝ T-10 Turbo-Meters were developed to meet the recognized need for greater accuracy in gas production and transmission measurement.
    The compact, rugged design of these meters, coupled with their direct digital readouts, provides reliable and accurate field measurement data.

    Sensus Mark II Turbo-Meters established Sensus Metering Systems as the leader in turbine meter gas measurement. The 4 – 12″ Turbos feature a top entry design that allows an interchangeable measurement module to be removed from the meter body while the body remains in-line. All moving parts are housed in a sealed chamber protected from line contaminants. The unique design of the 45° or 30° blade angle rotor allows the meter to extract the maximum amount of kinetic energy from flowing gas. Mark II Turbo-Meters accept a multitude of meter-mounted readout devices and provide calibrated pulse outputs for electronic measurement.

    The Sensus TPL-9 Turbo-Meter is a 90° angled body meter that permits compact installations with the meter inlet in either a horizontal or vertical plane. The Sensus T-10 Turbo-Meter is a straight-through (wafer-style) meter designed for high pressure applications. Both 2″ and 3″ meters come with cast steel bodies and interchangeable modules.
