Description & Features

The FI750 Series in-line flow indicator is designed for continuous flow monitoring in hydraulic systems, covering a working range of 2 to 30 L/min (0.5 to 8 US gpm) with a maximum permissible flow of 34 L/min (9 US gpm). Rated to 420 bar (6000 psi), it delivers flow accuracy of plus or minus 4% full scale and temperature accuracy of plus or minus 2.5 degrees C, making it a dependable reference instrument across a wide range of mobile and industrial hydraulic circuits.

Constructed from aluminium 2011T6 with mainly brass internals and FKM seals, the FI750-30ASOT is compatible with mineral oils to ISO 11158. Main ports are 1-1/16 inch 12 UNF SAE ORB with 1/4 inch NPTF top ports. Fluid temperature tolerance runs from 20 to 80 degrees C in continuous service, with intermittent capability up to 110 degrees C. Ambient use is rated between minus 10 and 50 degrees C. Net weight is 1.3 kg (2.9 lbs).

Question by: Karen W on Jul 11, 2025, 8:40 PM
porting on this one, are the main ports 1-1/16" SAE ORB or something else? trying to figure out if it'll drop into an existing test circuit without swapping fittings
Answer by: Customer Support on Jul 13, 2025, 7:23 AM
Main ports are 1-1/16"-12 UNF #12 SAE ORB, so if your circuit is already plumbed with SAE ORB fittings at that size, you're good to go. There are also 1/4" NPTF top ports if you need to tap in a gauge or secondary connection. Worth double-checking your thread count before assuming it's a straight swap, but the SAE ORB main ports are a common enough standard that most test circuits won't need adapters.
