FI750 Series Hydraulic In-Line Flow Indicator FI750-120BNWT | FT5758-21

Description & Features

The WEBTEC FI750 Series in-line flow indicator is engineered to deliver precise monitoring of hydraulic system flow rates ranging from 4 to 120 L/min (1 to 32 US gpm) and withstands pressures up to 420 bar (6000 psi). Designed with brass CW614N and featuring FKM seals, this robust flow indicator is compatible with water and mineral oils to ISO 11158 standards. It operates efficiently within fluid temperatures of 20 to 80°C (65 to 176°F) and can handle intermittent peaks up to 110°C (230°F). The device's main ports are 3/4" NPSF, and top ports are 1/4" NPTF, ensuring versatile connectivity in hydraulic systems.

With a flow accuracy of ±4% full scale and temperature accuracy of ±2.5°C (±5°F), the FI750-120BNWT model provides reliable performance in varied operating conditions. Weighing 3.5 kg (7.7 lbs), this compact indicator is ideal for industrial use where precision and durability are critical.
