Description & Features

The WEBTEC FI1500 Series in-line flow indicator is designed for continuous flow monitoring in hydraulic systems where both flow rate and fluid temperature need to be visible at a glance. Rated to 350 bar (5000 psi) and covering a flow range of 20 to 400 L/min (5 to 100 US gpm), model FI1500-400ASO delivers flow accuracy of plus or minus 4% full scale and temperature accuracy of plus or minus 2.5 degrees C (5 degrees F).

The aluminium 2011T6 body and predominantly brass internals are sealed with FKM seals, making the unit compatible with mineral oils to ISO 11158. Main porting is 1-7/8 inch -12UN #24 SAE ORB, with 1/4 inch NPTF top ports. Fluid temperatures up to 80 degrees C are supported in continuous service, with intermittent tolerance to 110 degrees C. Ambient service range spans -10 to 50 degrees C (14 to 122 degrees F). The unit weighs 3.2 kg (7 lbs).

Question by: Kirk D on Apr 5, 2026, 10:40 AM
porting on this one, is it SAE ORB or something else? got a #24 fitting on the manifold and want to make sure it drops right in
Answer by: Customer Support on Apr 6, 2026, 3:52 PM
Main ports are 1-7/8"-12UN #24 SAE ORB, so that lines up directly with a #24 SAE ORB fitting on your manifold. There are also 1/4" NPTF ports on top if you need accessory connections. No adapters needed on the main line as long as your manifold matches that thread spec.
