Portable/Handheld Ultrasonic Flowmeter BR.TUF-2000P

1. Product Introduction

The portable ultrasonic flowmeter achieves non-contact flow measurement. Simply install the sensors on the outer wall of the pipeline to complete flow measurement, offering convenience and accuracy. When paired with a clamp-on temperature sensor, it can also easily measure temperature and heat.

Widely used in industries such as tap water, heating, water conservancy, metallurgy, chemical, machinery, and energy, it can be used for production monitoring, flow comparison, temporary detection, flow inspection, water balance debugging, heat network balance debugging, and energy-saving monitoring. It is an essential tool for flow and heat detection.
