Description & Features

The FI750 Series in-line flow indicator is designed for precision monitoring of hydraulic systems, handling pressures up to 420 bar (6000 psi) and flow rates between 4 and 120 L/min (1 to 32 US gpm). Its robust construction, featuring an aluminium body and mainly brass internals, ensures durability and reliability in demanding industrial environments. The device offers a flow accuracy of ±4% full scale and a temperature accuracy of ±2.5°C (±5°F), making it suitable for various operation requirements.

Compatible with mineral oils to ISO 11158, the flow indicator operates effectively within a fluid temperature range of 20 to 80°C (65 to 176°F), and can withstand intermittent temperatures up to 110°C (230°F). The main ports are 1 - 1/16” - 12 UNF #12 SAE ORB, with top ports at 1/4” NPTF, accommodating easy integration into existing systems. With a net weight of 1.3 kg (2.9 lbs), this flow indicator is compact yet powerful, ideal for accurate hydraulic flow monitoring.

Question by: Barb C on Dec 25, 2025, 10:19 PM
porting on this one, are those main ports standard SAE ORB or something proprietary?
Answer by: Customer Support on Dec 27, 2025, 9:22 AM
Standard fittings all around. The main ports are 1-1/16" - 12 UNF #12 SAE ORB, and the top ports are 1/4" NPTF. Both are common enough that you shouldn't have trouble sourcing adapters or making a direct connection in most hydraulic plumbing setups.

How does the FI750 Series handle flow accuracy?
Answer by: Customer Support on Mar 29, 2026, 7:14 AM
For inline flow checks, the FI750 Series maintains a flow accuracy of ±4% full scale. This ensures that you can trust the readings for most hydraulic applications, providing reliable data up to its max flow capacity of 120 L/min or 32 US gpm.
