Specifications
SAMPLE SPECIFICATION FOR PRESSURE MONITORS
Pressure Monitors must be installed above ground and be mobile in the field (lift & shift). Pressure monitors inside the hydrant barrel that may impact flow, or that may get drawn into the fire pump during operation are not allowed.
A: Physical Characteristics
- Low profile weatherproof unit
- Hydrant mounted - Installed on a 2 1/2” NHT standard hose nozzle outlet
- Provides an internal ¼” NPT to mount / retrofit to allow pressure monitoring elsewhere if desired
B: Wireless Communication
- Incorporate an integral antenna
- Reports pressure data and / or transient events via internal cellular modem
- Utilize a low power, LTE/ Cat 1 cellular communication modem certified on Verizon Wireless
- Allow for low energy wireless connectivity via Bluetooth with a range of 20 feet in open field line of site
- Hydrant based pressure monitor must be free of cables, or similar connectors, in order to operate or transfer data from the device
C: Equipped with a Security Cover
- Incorporate a separate high impact security cover
- Include lockout hasps to provide a secure lockable cover to prevent vandalism
D: Alarm Notification Capable
- Provide defined alarm notifications based on user set pressure settings
- Send real time alarm alerts via email or text
- Send real time alarm alerts for pressure changes and / or transient events as defined by user
E. Pressure Measurements and Recording
- Pressure monitors must be available in ranges from 100psi, 200psi, 300psi, and 500psi
- All measurements are to be documented with date and time stamp
- Sample rates must be programmable from 4 samples/sec for a maximum of 8 hours
- Data intervals programmable from 1 sample/sec up to 8 hours
- Pressure monitor memory to hold up to 82,000 data values
- Capable of recording entire transient events at a rate of 256 samples/sec for up to 8 hours
- Pressure rate-of-change; either positive or negative; user configurable up to 125 transient events, with a maximum of 41,000 data values
F: GIS Capable
- Allow data to remain with a specific location
- Provide GIS and web-based visualization
G: Power Source
- Powered by a factory installed lithium battery
- Battery shall be field replaceable without the need to disassemble any portion of the hydrant barrel or remove the hydrant rod.
H: Software
- Data must be wirelessly transmitted from the pressure monitor to a single platform solution to proactively monitor asset performance
- Provide support for smart water management, including workflows to map, manage, measure, and improve asset performance.
- Provides a GIS-centric cloud and mobile platform to view measurements
- Allow user to monitor system pressures, as well as trends, min, max and average pressure history at any user defined interval
- Allow unlimited user access
- Provide mobile access to measurements
- Provide GIS view
- Provide dashboards to view performance & system health
- Allow functionality to export data to Excel or CSV
I: Environmental Conditions
- Operating field temperature to be 40° to 150°F [4° to 66°C]
- NEMA 4x/IEC IP65 enclosure (weatherproof)
- Certified to NSF/ANSI/CAN 61 & NSF/ANSI 372
J: Pressure monitors must:
- Have a manufacture’s published warranty against defects in material or workmanship for a period of 1 year from date of purchase
- Be AFC SEPMER RPM™ (Remote Pressure Monitor) by AMERICAN Flow Control® or pre-approved equal
