Ask A Question

Description & Features

The WEBTEC FI1500 Series in-line flow indicator is designed for continuous flow and temperature monitoring in hydraulic systems handling mineral oils or water. Rated to 350 bar (5000 psi) with a working flow range of 20 to 400 L/min (5 to 100 US gpm), the FI1500-400BSW delivers flow accuracy of ±4% Full Scale and temperature accuracy of ±2.5°C, making it suitable for demanding mobile and industrial hydraulic circuits.

Fluid temperatures up to 80°C are supported in continuous service, with short-term tolerance to 110°C. Connections are made via 1-7/8" -12UN #24 SAE ORB main ports, with 1/4" NPTF top ports. The brass CW614N body with FKM seals provides good compatibility across a range of hydraulic fluids, and the unit weighs 8.3 kg, reflecting its robust construction for high-pressure in-line service.
