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.

Installation Guide
Pipe cutting step
1. Cutting the Pipe

According to installation point selection requirements, cut a section of the pipe at the installation location.

Nut insertion step
2. Insert the Nuts into the Pipe

Unscrew the two nuts from the meter and insert them into the pipe.

Pipe joint gluing step
3. Glue the Pipe Joints

Apply PVC glue to the two pipe joints on the instrument and plug them into the pipes.

Flow meter installation step
4. Install the Flow Meter

Place the meter in the middle and tighten the nut to complete the installation. Pay attention to the flow direction during installation.

Power connection step
5. Power On and Run

Connect the other end of the cable to a 24V DC power supply, power on and observe.
