The WEBTEC FI750 Series In-Line Flow Indicator, model FI750-120ABOT, is engineered for precise monitoring of hydraulic system flows ranging from 4 to 120 L/min (1 to 32 US gpm). It operates efficiently under pressures up to 420 bar (6000 psi), making it ideal for demanding industrial applications. The flow indicator offers a flow accuracy of ±4% full scale and a temperature accuracy of ±2.5°C (±5°F), ensuring accurate readings in varying conditions.
This robust unit is designed to handle fluid temperatures from 20 to 80°C (65 to 176°F) continuously, with the capability of withstanding up to 110°C (230°F) intermittently for less than 10 minutes. Constructed with an aluminum 2011T6 body and mainly brass internals, it features FKM seals for enhanced durability. Compatible with mineral oils to ISO 11158, the device is equipped with 3/4" BSPP main ports and 1/4" BSPP top ports for versatile connectivity. With a net weight of 1.3 kg (2.9 lbs), it combines performance with manageable size.

what's the pressure rating on this thing? running a system that spikes pretty hard and I don't want to blow out a meter

Rated to 420 bar (6000 psi), so it can handle serious system pressure without issue. The flow range runs from 4 to 120 L/min (1 to 32 US gpm), and accuracy is plus or minus 4% of full scale. As long as your spikes stay under that 420 bar ceiling, you're in good shape.
