Description & Features

The WEBTEC FI750 Series in-line flow indicator is a compact monitoring instrument designed for hydraulic circuits handling flows from 2 to 16 L/min (0.5 to 4 US gpm) at pressures up to 420 bar (6000 psi). Flow accuracy is rated at ±4% full scale, and the built-in temperature function delivers a reading accuracy of ±2.5°C / ±5°F. Fluid temperature capability extends from 20 to 80°C (65 to 176°F) in continuous service, with intermittent tolerance up to 110°C (230°F) for short periods not exceeding ten minutes.

The FI750-16ASOT connects via 1-1/16" 12 UNF #12 SAE ORB main ports, with 1/4" NPTF top ports for supplementary connections. The aluminium 2011T6 body keeps weight to 1.3 kg (2.9 lbs) while mainly brass internals and FKM seals ensure compatibility with mineral oils conforming to ISO 11158. Ambient temperature range is -10 to 50°C (14 to 122°F).

Question by: Brent B on Dec 8, 2025, 12:10 PM
porting on this one, are those main connections SAE ORB or something else? got a #12 fitting already on the line and want to make sure it drops right in
Answer by: Customer Support on Dec 10, 2025, 7:47 AM
Main ports are 1-1/16" - 12 UNF #12 SAE ORB, so your existing #12 fitting should mate up without adapters. The top ports are 1/4" NPTF if you need to tap into those for any auxiliary connections. Body is aluminum 2011T6, so it's reasonably light at 1.3 kg installed.
