F103 Weatherproof Flow Totalizer
F103 Weatherproof Flow Logger / Totalizer
With linearization, analog and pulse signal outputs

F103 Overview

The versatile F103 WP Flow Totalizer is your best choice for flow monitoring applications. It is perfect for new installations and to replace existing flow analyzers in the field. Its rugged construction, unique plug-and-play design and attractive pricing makes the F103 the perfect flow logger for liquid and gas flow measurement in Class I, Division 2 hazardous areas.


  • CSA Class I, Division 2, Non-Incendive rating for the United States and Canada.
  • Excellent performance in harsh weather conditions like rain, snow, sandy deserts and temperatures between -40°F up to 158°F.
  • Intuitive “Know one, know them all!” configuration menu with quick setup function, saving time, cost and aggravation.
  • Easy configurable via PC with free downloadable Configuration Software.
  • Excellent pricing and fast delivery times.


  • Displays simultaneous linearized flow rate and total, as well as accumulated total, daily total and 15 previous day totals.
  • Flow logging to survey daily operation and unexpected events with 600 daily, 1500 interval and 724 event logs (optional).
  • Large display with 0.7” numeric and 0.3” alphanumeric digits.
  • Smart K-factor configuration for volumetric or mass flow.
  • 15 linearization points for high accuracy at the full flow range.
  • Auto backup of settings and running totals.
  • Digital scaled, unscaled and “isolated solid state” outputs.
  • Isolated, loop powered 4 – 20mA output.
  • Modbus RS485 communication.
  • Ability to process all types of signals: Sine wave (coil), NPN / PNP pulse, Reed-switch and Isolated active pulse signals.
  • Power requirements: long life lithium battery, 6 – 30V DC or loop powered analog 4 – 20mA output.
