Ultrasonic Plus Meters
The E-Series® Ultrasonic Plus meter uses solid-state ultrasonic transit time technology to measure cold potable water and incorporates an integrated valve into the lay length of the meter. The integrated valve allows remote flow restriction of water service in residential utility applications.
Authorized utility personnel can actuate the valve via a command sent from BEACON® SaaS (Software as a Service) to an ORION® Cellular endpoint connected to the meter.
BEACON displays the status of the valve (open, partial or restricted) and upon a command to transition the valve, confirms the success of that actuation. The status of the valve is also indicated on the physical meter via a position-indicating LED.
E-Series Ultrasonic Plus meters comply with the lead-free provisions of the Safe Drinking Water Act, are certified to NSF/ANSI/CAN Standards 61 and 372, and carry the NSF 61 marking. All components of the meter comprise the certified system. E-Series Ultrasonic Plus meters comply with the applicable portions of the most recent revision of AWWA Standard C715.
All electronic components utilized in the meter and RF Transceiver design comply with applicable FCC Part 15 standards and AWWA C707 for encoded remote reading systems.
