The WEBTEC FI750 Series in-line flow indicator is engineered for reliable performance in demanding hydraulic systems. With a maximum flow capacity of 60 L/min (16 US gpm) and capable of withstanding pressures up to 420 bar (6000 psi), this flow indicator is ideal for rigorous applications. It offers a flow accuracy of ±4% full scale, ensuring dependable readouts for critical use. The device operates effectively within a fluid temperature range of 20 to 80°C (65 to 176°F), with intermittent use up to 110°C (230°F), and an ambient temperature range of -10 to 50°C (14 to 122°F).
Constructed with durable aluminum 2011T6 and featuring mainly brass internals, the FI750 Series is built to last. It is compatible with mineral oils conforming to ISO 11158, with other fluid options available on request. The unit features main ports with 1 - 1/16" - 12 UNF #12 SAE ORB and top ports of 1/4" NPTF, ensuring versatile connectivity in various hydraulic settings.

How does the FI750 Series Flow Indicator handle high-pressure situations in hydraulic systems?
Answer by: Customer Support on Feb 18, 2026, 7:16 AM
With a maximum pressure rating of 420 bar (or 6000 psi), the FI750 Series Flow Indicator is well-suited for high-pressure hydraulic systems. It effectively monitors flow in these demanding environments, ensuring accurate readings even under intense conditions.
Question by: Dean B on Jan 16, 2026, 8:11 PM
ports on this thing, are they SAE ORB or threaded pipe? trying to figure out if my existing fittings will work before I order
Answer by: Customer Support on Jan 18, 2026, 7:38 AM
Main ports are 1-1/16" - 12 UNF #12 SAE ORB, so if your lines are already set up for SAE O-ring boss fittings at that size, you're good to go. The top ports are 1/4" NPTF, which is a tapered pipe thread. Two different connection types on the same unit, so worth double-checking both ends of your plumbing before you commit.
