Product Overview

FL101 is specially designed for measuring the flow of various liquids in pipelines, enabling real-time flow measurement in production processes. The instrument outputs digital signals, analog signals, and more to facilitate measurement and control of production processes.

With industrial upgrading requirements, instruments need rich outputs for automation. Traditional flow meters often have limited outputs that cannot meet on-site needs and require replacement in original positions. Flo-Instruments introduces an in-line flow meter with full straight pipe design, no pressure loss, double union connection, and simple installation.

Key Benefits
Advanced Display

Four-line OLED display showing date, signal, instantaneous, and accumulated data. Clear visibility in low light and dim environments.

FL101 flow meter display interface
User-Friendly Interface

Innovative dropdown menu method with four touch buttons for easy setup. Supports Simplified Chinese, Traditional Chinese, and English language switching.

Robust Construction

IP66 rated with injection molding structure. Double union connection for easy and reliable installation.
