Product Overview
The SX-FULB Series clamp-on ultrasonic flowmeter is a non-contact, non-invasive liquid flow measurement device. Based on the ultrasonic transit-time principle, it measures liquid flow inside the pipe without cutting the pipe or interrupting the process. The clamp-on design provides no pressure loss and no process-fluid contact, making it suitable for flow monitoring and management in industrial applications
Typical Measurements
- Instantaneous flow rate
- Accumulated flow total
- Flow velocity
- Signal quality
Main Features
-
Non-Contact, Non-Invasive —— No pipe cutting or wall damage required; clamp-on installation with a
single screwdriver -
Transit-Time Ultrasonic Principle —— Rapidly and accurately measures liquid flow inside the pipe without
interrupting the process -
High Accuracy & Repeatability —— Accuracy ±1 % F.S.; repeatability 0.15 % F.S.
- No Pressure Loss, No Contamination —— Completely external installation; no contact with process fluid
- One Clamp, Two Pipe Sizes —— Reversing the base bracket 180° selects between two supported pipe diameters
- Multiple Alarm Output Modes —— Instantaneous flow mode, zone mode, and totalizer mode
- Rotatable TFT-LCD Display —— Screen supports 4 orientation directions, allowing multiple installation positions
- Compatible Pipe Materials —— Metal pipe (stainless steel, carbon steel, copper) and plastic pipe (PVDF, PVC, PPR, PPH, PFA, HDPE)
-
Multiple Measurable Media —— Water, chemical liquids, organic liquids, and oils
-
Multiple Output Options —— RS-485 / Modbus RTU, 4–20 mA, and NPN/PNP discrete output
