Precision Handheld Ultrasonic Flow Meter – Portable Water & Liquid Flow Rate Analyzer

Description

The High Accuracy Handheld Ultrasonic Water Flow Sensor is a full-featured, portable transit-time ultrasonic flow meter designed for fast, accurate, and non-invasive liquid flow measurement. Whether you’re verifying the performance of another flow meter or conducting long-term data logging, this handheld device is the ideal solution.

This model comes with clamp-on transducers, eliminating the need for pipe cutting or tapping—just clamp the sensors onto the outside of the pipe for instant readings. Designed for ease of use, portability, and flexibility, the device is perfect for temporary flow measurement across multiple sites. Its rugged design makes it suitable for use in various industrial and plumbing systems, helping verify pump, sensor, and valve performance with precision.

Measuring principle

Transfer time technical means the ultrasonic signal from the transducer is transmitted and received through the m oving liquid, there w ill be a difference between the upstream and downstream transit time, which can be u sed to calculate flow and velocity.
