FL101 Clamp-on Ultrasonic Flowmeter

Providing flow measurement and control solutions with simple installation and full straight pipe design.

Product Overview

The FL101 In-Line Ultrasonic Flow Meter 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 demanding rich outputs for automation, traditional flow meters with limited outputs often fail to meet on-site needs. Flo-Instruments addresses this with an in-line flow meter featuring full straight pipe design without pressure loss, double union connection, and simple installation.

Key Benefits

Advanced Measurement Technology

Built-in advanced measurement chip with time resolution up to 20ps

Clear Display

Four-line OLED display showing date, signal, instantaneous, and accumulated data. Easy to read in low light and dim environments.

User-Friendly Interface

Innovative drop-down 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 and double union connection for easy and reliable installation.

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

Step 2: Insert Nuts into Pipe

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

Step 3: Glue Pipe Joints

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

Step 4: Install Flow Meter

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

Step 5: Power On and Run

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