Ask A Question

Description & Features

The WEBTEC FI1500 Series in-line flow indicator is designed for continuous monitoring of flow rates in hydraulic systems, covering a working range of 10 to 200 L/min (5 to 50 US gpm) with a flow accuracy of plus or minus 4% full scale. Rated to 350 bar (5000 psi), the unit is well suited to demanding industrial hydraulic circuits where pressure and temperature conditions are variable.

Fluid temperatures up to 80°C (176°F) are supported in continuous use, with short-term tolerance to 110°C (230°F), while ambient conditions between -10 and 50°C (14 to 122°F) are accommodated. Temperature readings are accurate to plus or minus 2.5°C (plus or minus 5°F). The aluminium 2011T6 body with mainly brass internals and FKM seals is compatible with mineral oils to ISO 11158. Main ports are sized at 1-7/8" -12UN #24 SAE ORB, with 1/4" NPTF top ports. Net weight is 3.2 kg (7 lbs).

Question by: Judy K on May 26, 2026, 10:12 PM
porting on this one, is it 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 May 28, 2026, 9:15 PM
Main ports are 1-7/8"-12UN #24 SAE ORB, so if your circuit is already plumbed with SAE ORB at that size you're in good shape. There are also 1/4" NPTF top ports. Worth double-checking your existing fittings against those specs before you order, but for most standard hydraulic test setups this is a pretty common port configuration.

How does the FI1500 Series measure flow accurately within its range?
Answer by: Customer Support on Dec 8, 2025, 7:40 PM
For inline flow checks, the FI1500 Series ensures accuracy within ±4% of Full Scale across its range of 10 to 200 L/min (5 to 50 US gpm). This makes it reliable for various hydraulic applications needing precise flow measurements.
