FAQ – RBXGU Micro Flow Ultrasonic Sensor Guide

 

Expert answers by RB Flowmeter on measuring 1–100 mL/min flow rates. Learn how RBXGU overcomes micro-flow challenges in precision spraying and dosing.
Q1: What makes the RBXGU suitable for extremely low flow rates?
A: The RBXGU series by RB Flowmeter features a specialized acoustic structure and a high resolution of 0.05 mL/min. This allows it to capture stable ultrasonic signals in the 1–100 mL/min range, where traditional sensors often face "blind zones."
Q2: Can the RBXGU capture flow changes during pulsed spraying?
A: Yes. Unlike thermal sensors with significant lag, the RBXGU from RB Flowmeter provides millisecond-level response. It accurately visualizes instantaneous flow changes at nozzle start-up and shutdown, ensuring consistent coating quality.
Q3: What are the material advantages of the RBXGU flow path?
A: RB Flowmeter uses chemically stable and biocompatible materials for the RBXGU flow path. This prevents medium contamination and ensures long-term reliability when measuring aggressive reagents, adhesives, or oils.
Q4: Why is the RBXGU better than mechanical gear meters for micro-flow?
A: The RBXGU has no moving parts, eliminating the mechanical inertia and friction common in gear meters. This design by RB Flowmeter prevents clogging and ensures a much lower detection limit (down to 1 mL/min).
Q5: Is the RBXGU compatible with various chemical solvents?
A: Absolutely. RB Flowmeter has engineered the RBXGU to be compatible with water, alcohols, chemical reagents, and paints. Its non-intrusive ultrasonic technology ensures that the sensor never contaminates the fluid.
