Detailed introduction
Product Features
- Easy installation—no pipe cutting required.
- No adjustment required—deduction and measurement occur simultaneously.
- LCD color display with 4-way adjustable screen rotation.
- The clamp-on ultrasonic flow meter employs the time-difference method for measurement, enabling installation in just four simple steps without the need to cut or disrupt the pipeline. The measurement process is non-contact, requiring no contact with the fluid medium and no shutdown of operations.
- The product is standardly equipped with an RS485 communication interface commonly used in industrial settings, supports the MODBUS protocol, and enables remote monitoring and data transmission of the instrument.

Installation Method
Step 1: Clean the pipeline Perform surface treatment on the pipeline to thoroughly remove loose paint, rust, dirt, and other contaminants from the surface. | Step 2: Install the pipe clamp Clamp the upper and lower pipe clamps onto the selected pipe location. If loosening is detected, affix adhesive pads to the inner wall of the lower clamp to enhance the clamping force. | Step 3: Tighten the screw Tighten the four screws connecting the upper and lower pipe clamps securely to ensure stability and prevent any looseness. | Step 4: Power on to begin measurement. The actual pipe outer diameter, wall thickness, and material parameters can be adjusted via the “Pipeline Parameter Settings” menu item to ensure measurement accuracy. |
