Ask A Question

Description & Features

The RFI120-S-6 is a reversible flow indicator from WEBTEC's RFI Series, designed to monitor flow in both directions across a working range of 10 to 120 L/min (4 to 32 US gpm). Rated to 420 bar (6,000 psi), it suits demanding hydraulic circuit monitoring where high-pressure capability is essential. Flow accuracy is ±4% of full scale, with a temperature reading accuracy of ±2.5°C (±5°F).

Fluid temperature limits span 20 to 80°C (65 to 176°F) for continuous service, with intermittent tolerance up to 110°C (230°F) for short durations. Ambient use is rated from -10 to 50°C (14 to 122°F). The body is machined from aluminium 2011T6, with stainless steel and brass internal components, and NBR or FKM seals for compatibility with mineral oils to ISO 11158. Connection is via a 1-5/16" -12UN #24 SAE ORB port. Net weight is 2 kg (4.4 lbs).

Question by: Stan S on Jun 12, 2025, 7:08 AM
what's the max pressure this thing handles? got a system running at 5500 psi and want to make sure it won't be a problem
Answer by: Customer Support on Jun 13, 2025, 5:50 PM
Rated to 420 bar, which works out to 6000 psi, so 5500 psi puts you comfortably within spec. Flow range runs from 10 to 120 L/min (4 to 32 US gpm), and accuracy is plus or minus 4% of full scale. Port is a 1-5/16"-12UN #24 SAE ORB, so just confirm your line fitting matches before you bolt it in.

How do I know if the RFI120-S-6 flow indicator will fit my hydraulic system?
Answer by: Customer Support on Apr 9, 2026, 11:52 AM
The RFI120-S-6 flow indicator is designed with a 1-5/16” -12UN #24 SAE ORB porting, making it compatible with systems that use this connection type. It supports flow rates from 10 to 120 L/min and operates effectively under pressures up to 420 bar, ensuring it can handle demanding hydraulic systems.
