MC-III WP vs F103 WP Product Comparison

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.

Your advantages

  • CSA Class I, Division 2, Non-Incendive rating for the United States and Canada.
  • Key information at a glance: simultaneous linearized flow rate and total, 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).
  • Weatherproof: Excellent performance in harsh weather conditions like rain, snow, sandy deserts and temperatures between -40°F up to 158°F.
  • Robust IP67 / Type4X field enclosure. It is so rugged, even a truck can stand on it!
  • Intuitive “Know one, know them all!” configuration menu with quick setup function, saving time, cost and aggravation.
  • Excellent pricing and fast delivery times.


  • Large display with 0.7” numeric and 0.3” alphanumeric digits.
  • Smart K-factor configuration for volumetric or mass flow.
  • The quick set-up allows easy configuration of the most often used settings.
  • Easy configurable via PC with free downloadable remote configuration tool and special communication cable (ACE02/06/07).
  • Auto backup of settings and running totals.
  • 15 linearization points for high accuracy at the full flow range.
  • Ability to process all types of signals: Sine wave (coil), NPN / PNP pulse, Reed-switch and Isolated active pulse signals.
  • Digital scaled, unscaled and “isolated solid state” outputs.
  • Isolated, loop powered 4 – 20mA output.
  • Modbus RS485 communication.
  • Power requirements: long life lithium battery, 6 – 30V DC or loop powered analog 4 – 20mA output.
  • Remote control input to reset total or to lock the “clear total” button.
  • LED backlight.
