1.2 Meter Specifications
Solid state meters: All cold water meters must use solid state measuring technology with no moving
parts. The meter should be resistant to wear and impurities in the water. All sensors and electronics
should be designed so that no direct exposure is made with fluid. The meters should be hermetically
closed and vacuumsealed to prevent humidity from reaching the electronics and avoid condensation
between the glass and display. The manufacturer should have field proven experience in
manufacturing solid state meters with a documented failure rate over ten years of less than 0.3 %.
Meters should be produced in an ISO 9001C facility.
Accuracy: Maximum permissible error should fall in accordance to AWWA C 708 ± 3.0% in
extended low flow range and ± 1.5% in normal and high flow range. The minimum start flow range
should measure at .015 GPM for 5/8”, 5/8”X¾”, ¾” meter sizes. The minimum start flow range should
be .04 GPM for 1” meter size, .06 for 1.5” meter size and .1 for 2” meter size.
Integrated RF communication module: The meter and RF communication module should be one
single compact unit hermetically sealed for easy installation reducing labor cost and time. The meter
must be IP68 rated and submersible suited for installation in flooded meter pits.
Dual band radio: The meter must utilize a Wireless MBus standard (US localization of European
standard for remote meter reading protocol EN137574), that supports C1 and C2 (unidirectional
and bidirectional) communication mode operating within FCC part 15 for the 902928 MHz band for
driveby operation. Also, must additionally support frequency within the 450470 MHz band for fixed
network operating within FCC part 90.
Data Storage: The meter data must store data loggers in the EEPROM, retrievable by optical eye via
Bluetooth or USB. Must provide a minimum of 20 years of annual data, 36 months of monthly data,
hourly values for 100 days and the last 50 information codes such as leak, reverse, burst, dry,
tamper, and battery capacity. Logged data must be viewable on a mobile device or sent to the
headend server.
Data options: To support technology changes, feature enhancements, and transmission mode
changes the meter should be programmable. Firmware updates should be permissible over RF
without having to gain physical access to the meter and implemented in groups.
Standard data communication intervals will be every 3 hours or up to 8 times a day delivering the past
three hourly values and historical info codes. The meter transmission interval may be changed to
less frequent once per day at midnight, or more frequently every hour. If the transmissions are not
acknowledged by the collector, the meter must accumulate and resend hourly data for up to 24 hours.
The meter shall provide information codes on the following events;
Leak: Continuous flow for the past 24 hours based on a configurable limit of greater than 0.1%,
0.25%, 0.5%, 1.0% and 2.0% of maximum flow for meter size.
Reverse Flow: Indicating water is running in the opposite direction of normal flow. Reverse
flow should be logged in a separate internal register.
Burst: Indicating 30 minutes of flow based on a configurable limit greater than 5.0%, 10.0% of
20.0% of maximum flow.
Dry: Indication of air in the pipe and no water through the meter.
Tamper: Indication that electronics or meter has been compromised.
Low ambient temperature: Temperature lower than configurable limit of 37 °F or 43 °F to
indicate possible freezing.
High ambient temperature: Temperature higher than configurable limit of 95 °F or 122 °F to
indicate high temperatures.
Maximum and Minimum flow: The meter should provide a daily flow rate maximum and
minimum value to help identify possible leaks in the supply line or blockage in the meter
LCD and Register Face
The meter should include an easily readable LCD display including nine digit resolution, unit of
measure, billable digits for reference, and all active information codes. Meter serial number
will be barcoded and visible on the register face, as well as meter size, maximum flow for
continuous operation, temperature range, FCC identification, NSF compliance, production
year, maximum operating pressure, type number and configuration code.

balancing analysis. The meter should be programmable by time zone.
Security: Data must be encrypted using AES 128bit encryption.
Installation: The meter may be mounted at any angle and position with no minimum straight pipe to
meet applicable AWWA accuracy standards.
When the meter is installed, the use of a mobile application should confirm that the meter is being
heard by one or more data collectors and verify the signal strength to determine whether the
installation is good before leaving the installation site.
Material: The meter housing will be made from either a polyphenylene sulfide (PPS) with fiberglass
reinforcement, stainless steel or lead free brass. The carbon footprint should document the meter’s
high reusability and low environmental impact including the recycling of materials. The threads shall
not be susceptible to cross threading and tightened to a maximum of 11 FT Lbs.
Certifications/Standards: Must be NSF 61 certified and apply to all applicable AWWA standards. Must
also comply to RF Exposure compliance Part 15 of FCC rules. The manufacturing and testing
process should be highly automated and only use materials approved for drinking water. Meters
should be disinfected before dispatch and hygienically controlled by frequent audits from external
accredited laboratories.

Operation: The meter should be able to operate accurately under a maximum pressure of 250 PSI for
meter sizes 5/8”, 5/8”X¾”, ¾” and 300 PSI for 1”, 1.5” and 2” meter sizes.
Data Collectors Specification: Data collectors should consist of a base box and top box to minimize
cable loss from the antenna to the base station. The bottom base box provides the network backhaul
communication method whether cellular modem or Ethernet and supplies power to the top box. The
base box should allow to up to four top box connections.
Installation and Configuration: The collector should be plug and play without requiring programming of
the base box alleviating the necessity of IT resources.
Built in Network Intelligence: Collector must be able to automatically power optimize to extend battery
life on the meter. To maximize performance the system should be able to monitor and adjust
transmission power of meters with very strong signals and those with lower signals. The system must
be able to select the optimal collector to read the meter, but in the event the collector is taken out of
operation, other collectors must take over reading the meters within its range.
Data Storage: The collector must support up to 25,000 meters and be able to store 30 days of hourly
Communication: Collector communication backhaul options should include either cellular modem or
Ethernet network.
