The Flo-Tronic Plus™ is based on a standard Flo-Meter™ with or without a manual flow control valve. It provides visual flow rate indication as required by NFPA and EN746 as well as an analog output in direct relation to the flow rate.

The Waukee new magnetic flow sensing technology is immune to problems associated with dirty oil. Ideal for customers who need to data log flow rates for compliance to NADCAP, AMS 2750D, or CQI 9.

  • Meets NFPA and EN746 requirements for visual indication of flow
  • Isolated 4-20mA current loop output
  • Over current and reverse polarity protection
  • Calibrated in our ISO/IEC17025-2005 Calibration Lab and traceable to NIST (National Institute of Standards and Technology)
  • Multipoint calibration
  • Simple Installation
  • Modbus/TCP communications
  • 1 Programmable relay out
  • Easily connects to any PLC or controller with differential or single ended analog inputs
  • Retrofittable to existing Waukee Flo-Meters
