Description
Overview
GAOTek Ultrasonic Flow Meter with Data-Logger (Wide Range) is designed for measuring variety of industrial liquids and with built-in data logger that can record time and signal status. It provides liquid flow online calibration. It has many advantages including high measurement accuracy, good consistency, battery power supply and simple operation. It is one of the smallest and lightest portable ultrasonic flow meters and is very convenient to carry. This ultrasonic flow meter has a self-diagnosis feature, suggesting that the current working status is normal. It has a built-in NiMH rechargeable battery, which allows more than 10 hours of continuous work.
