The WEBTEC FI750 Series In-Line Flow Indicator is an essential tool for monitoring hydraulic systems, offering precise flow measurement from 2 to 30 L/min (0.5 to 8 US gpm) at pressures up to 420 bar (6000 psi). Designed for compatibility with mineral oils to ISO 11158, this flow indicator supports a fluid temperature range of 20 to 80°C (65 to 176°F) for continuous use, with short-term tolerance up to 110°C (230°F). Its robust construction features an aluminium 2011T6 body and brass internals, ensuring durability in demanding environments. The device's flow accuracy of ±4% full scale and temperature accuracy of ±2.5°C (±5°F) provide reliable data for optimal system performance.
Main ports are equipped with 3/4" NPSF connections, while top ports utilize 1/4" NPTF. The FI750 Series is built to withstand ambient temperatures ranging from -10 to 50°C (14 to 122°F), making it suitable for varied industrial settings. With its compact design, weighing only 1.3 kg (2.9 lbs), this flow indicator is both lightweight and efficient, facilitating easy installation and integration into existing systems.

How well does this flow indicator work in high-temperature hydraulic systems?
Answer by: Customer Support on Nov 21, 2025, 7:47 AM
For systems with fluid temperatures between 20 to 80°C (65 to 176°F), the FI750 Series Hydraulic In-Line Flow Indicator performs reliably. It can also handle intermittent temperatures up to 110°C (230°F) for less than 10 minutes, making it suitable for high-temperature applications within those limits.
