Ask A Question

Description & Features

Designed for continuous service in hydraulic circuits, the WEBTEC FI750 Series in-line flow indicator provides visual flow monitoring across a range of 2 to 16 L/min (0.5 to 4 US gpm), with a maximum operating pressure of 420 bar (6000 psi). Flow accuracy is rated at ±4% Full Scale, and temperature indication is accurate to ±2.5°C, making it suitable for applications where both parameters need to be tracked.

The aluminium 2011T6 body, primarily brass internal components, and FKM seals support compatibility with mineral oils to ISO 11158. Main ports are 3/4" BSPP with 1/4" BSPP top ports. Fluid temperatures up to 80°C are supported in continuous use, with intermittent exposure up to 110°C (230°F). Ambient temperature range extends from -10 to 50°C (14 to 122°F). At 1.3 kg, the unit is compact enough for installation in space-constrained hydraulic systems.

Question by: Frank C on Nov 3, 2025, 10:03 PM
porting on this one is 3/4 BSPP for the mains -- does that mean the top ports are something different?
Answer by: Customer Support on Nov 5, 2025, 7:08 AM
Correct. The main inlet and outlet ports are 3/4" BSPP, but the top ports are 1/4" BSPP. Worth noting before you start planning fittings, because those two sizes serve different connection points on the unit.
