Companies introduce remote shut off valves for gas meters


Nashville, TN and Raleigh, NC, U.S.A. — (METERING.COM) — May 24, 2011 – Elster and Sensus have both introduced remote meter shut-off valves, Elster for its AC-250 diaphragm residential gas meter and Sensus as a stand-alone and for its FlexNet system.

The shut-off valve is aimed to provide utilities with remote access to, and control of, the natural gas flow through the meter to a downstream application. The device enables utilities to reduce operating costs, protect revenue, and enhance employee and customer safety.

The AC-250 remote shut-off valve fits neatly within an extended meter top. It meets the full AC-250 meter performance rating and industry intrinsic safety specifications.

Sensus’ Remote Gas Shutoff (RGS) device can be accessed as a walk-by or drive-by system, or for utilities that have deployed the FlexNet system from an office location. The device also provides accurate pressure readings from individual locations without needing to shut off service, as well as tilt and tamper detection alarms to alert utilities to potential gas theft. Further, if the unit detects a vibration, such as seismic activity, the unit will automatically shut down.

Remote shut-off of gas meters has been limited by safety concerns but as this forms an important functionality of an advanced metering infrastructure system, more work and devices of this type can be expected in the future.
