Handheld Ultrasonic Flowmeter

The OUF-H series hand-held ultrasonic flow meters use ultrasonic signals to measure flow rate by sending sound waves through a pipe. The time it takes for the signal to travel determines the flow velocity and volume. Powered by rechargeable batteries, its advantages include portability, easy installation, non-invasive measurement, and suitability for a wide range of pipe sizes and applications.

Product Features

The OUF-H series Hand-held ultrasonic flow meters enable non-contact and temporary measurement of liquid flow. The flow is measured by mounting the sensor on the outer wall of the pipe. It has the characteristics of small size, convenient carrying and accurate measurement.

Widely used in tap water, heating, water conservancy, metallurgy, chemical, machinery, energy, and other industries. It can be used for production monitoring, flow verification, temporary inspection, flow inspection, water meter balance debugging, heat network balance debugging, energy saving monitoring, and is a necessary tool for timely flow detection.

It has the following features:: No need to cut pipes for installation and it does not cause pressure loss.; Wide temperature range, the OUF-H series can measure from -30℃-160℃;; Multi language user interface: The flowmeter has LCD Display and Menu with four languages: Chinese, English, Italian and French; Built-in 24K data logger, store over 2000 lines measuring data; Large LCD display instantaneous flow, accumulated flow (positive, negative and net), velocity, working status etc.; Long battery life, built-in rechargeable NI-MH battery, provide over 12 hours of continuous operation; Wide pipe range, the OUF-H series can measure between DN15-DN6000 pipes with the following selections of sensors.
