Ultrasonic Flow Meter Portable Type
The portable ultrasonic flowmeter has a built-in printer and SD card memory, which can print the set measurement value in real-time or at a regular time.
It is widely used in tap water, heating, water conservancy, metallurgy, chemical industry, machinery, energy, and other industries, and can be used for production monitoring, flow comparison, temporary detection, flow patrol inspection, water balance commissioning, heat network balance commissioning, energy conservation monitoring. It is a necessary T instrument for flow and heat detection.
