Flow3

Flow3 is our most flexible and affordable hydrometer. Combined with a WeatherTRAK® controller, you’ll get the protection of a master valve, visibility of a flow sensor and submetering capabilities of a water meter. Because the flow sensor, master valve and water meter are all integrated into a single, powerful unit, it’s easy to install, even in tight locations.

Flow3 is ideal for:

  • New system installations
  • Retrofitting existing systems
  • Sites with limited install space
  • High pressure situations

Benefits

  • Highly accurate performance makes it ideal for most commercial sites.
  • Built-in master valve so if a break is detected, the master valve will automatically close and prevents damage.
  • Easy to read register with sub-metering and displays that won’t lose data.
  • Easy to install.
  • Built to last: based on heavy-duty construction and no moving parts.
