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

  1. Low profile weatherproof unit
  2. Hydrant mounted - Installed on a 2 1/2” NHT standard hose nozzle outlet
  3. Provides an internal ¼” NPT to mount / retrofit to allow pressure monitoring elsewhere if desired

 B: Wireless Communication

  1. Incorporate an integral antenna
  2. Reports pressure data and / or transient events via internal cellular modem
  3. Utilize a low power, LTE/ Cat 1 cellular communication modem certified on Verizon Wireless
  4. Allow for low energy wireless connectivity via Bluetooth with a range of 20 feet in open field line of site
  5. 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

  1. Incorporate a separate high impact security cover
  2. Include lockout hasps to provide a secure lockable cover to prevent vandalism

D: Alarm Notification Capable

  1. Provide defined alarm notifications based on user set pressure settings
  2. Send real time alarm alerts via email or text
  3. Send real time alarm alerts for pressure changes and / or transient events as defined by user

 E. Pressure Measurements and Recording

  1. Pressure monitors must be available in ranges from 100psi, 200psi, 300psi, and 500psi  
  2. All measurements are to be documented with date and time stamp
  3. Sample rates must be programmable from 4 samples/sec for a maximum of 8 hours
  4. Data intervals programmable from 1 sample/sec up to 8 hours
  5. Pressure monitor memory to hold up to 82,000 data values
  6. Capable of recording entire transient events at a rate of 256 samples/sec for up to 8 hours
  7. 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

  1. Allow data to remain with a specific location
  2. Provide GIS and web-based visualization

 G: Power Source

  1. Powered by a factory installed lithium battery
  2. Battery shall be field replaceable without the need to disassemble any portion of the hydrant barrel or remove the hydrant rod.

 H: Software

  1. Data must be wirelessly transmitted from the pressure monitor to a single platform solution to proactively monitor asset performance
  2. Provide support for smart water management, including workflows to map, manage, measure, and improve asset performance.
  3. Provides a GIS-centric cloud and mobile platform to view measurements
  4. Allow user to monitor system pressures, as well as trends, min, max and average pressure history at any user defined interval
  5. Allow unlimited user access
  6. Provide mobile access to measurements
  7. Provide GIS view
  8. Provide dashboards to view performance & system health
  9. Allow functionality to export data to Excel or CSV

 I: Environmental Conditions

  1. Operating field temperature to be 40° to 150°F [4° to 66°C]
  2. NEMA 4x/IEC IP65 enclosure (weatherproof)
  3. Certified to NSF/ANSI/CAN 61 & NSF/ANSI 372 

 J:  Pressure monitors must:

  1. Have a manufacture’s published warranty against defects in material or workmanship for a period of 1 year from date of purchase
  2. Be AFC SEPMER RPM™ (Remote Pressure Monitor) by AMERICAN Flow Control® or pre-approved equal
