| Description |
The S301 ultrasonic flowmeter is an economical but robust flowmeter. It utilizes cutting-edge technologies, such as balanced ultrasound transmission, digital signal processing, self adaptation, etc., to achieve high performance.
The S301 can be equipped with a pair of clamp-on transducers to measure liquid flow rate from outside of a pipe non-intrusively. It can also be equipped with a pair of insertion transducers or a flow-cell transducer to measure liquid flow with excellent long-term stability and high accuracy.
• S301B clamp-on flowmeter
• S301C insertion flowmeter
• S301G flow-cell flowmeter
Due to the proprietary signal quality tracking and self-adaptation algorithm, S301 is able to tune itself to the optimal condition when the liquid property changes or different transducer is connected |
