Handheld Ultrasonic Flow Meter

GUF100 Handheld Ultrasonic Flow Meter | GAIMC

Product Overview

The GUF100 is a portable handheld ultrasonic flow meter developed by Xi'an Gavin Electronic Technology Co., Ltd. Based on transit-time ultrasonic principle, it adopts non-intrusive clamp-on transducers for flow measurement without pipe cutting or production shutdown—eliminating pressure drop and fluid contamination risks.

Equipped with a 4×16 character backlit LCD display, it supports multiple languages (Chinese, English, Italian, customizable) and built-in 24K data logger (stores over 2000 lines of data). The rechargeable Ni-MH battery provides over 12 hours of continuous operation, making it ideal for on-site inspection and mobile measurement.

Compatible with pipe diameters from DN32mm to DN6000mm (bracket transducers up to DN7000mm), measuring medium temperature from -30℃ to 160℃. It is widely used for ultra-pure liquids, potable water, chemicals, sewage, cooling water, oil, beverages, and plant effluent.
