WeatherTRAK® 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
Features
Accurate performance for commercial sites
- Sizes: 1 ½” (Union), 2” (Threaded), 3”, 4” and 6” (Flanged)
- 8 to 860 gallons per minute flow range
- Accuracy across a wide flow range (up to ± 2% see chart on back)
Powerful mainline control
- Prevent catastrophic water loss
- Double-chambered valve provides quick-acting and positive opening and closing
Easy to read registerProvides on-site submetering
- Two register options: Photo Diode – high frequency or Reed Switch – low frequency
- Odometer style register displays won’t lose data
Easy to install
- Requires no straight pipe upstream or downstream of unit
- Low installation cost vs. installing each component separately
- Ideal for installations where space is limited
Built to last
- Heavy-duty cast iron construction with corrosion-resistant body
- Stainless steel encapsulated registers guaranteed against fogging due to moisture
Models
Register Options
Photo Diode
High frequency pulse output
For systems containing drip and/or high efficiency/rotary nozzles zones
- From 0.005 gallons per pulse
- 10 to 200 pulses per second (depending on flow rate)
- Superior leak visibility
- Combines an IR light source and a light sensitive diode (power supply included)
Reed Switch
High frequency pulse output
For systems with station flow rates of 10+ GPM and are less concerned about small leaks
- 1 gallon per pulse
- Leak indicator dial in the center of register
- Magnetic coupling activated
