CLAMPON ULTRASONIC FLOW METER: MODEL 301B
The ST301 ultrasonic flowmeter is a cost-effective yet robust solution for liquid flow measurement. It features advanced technologies like balanced ultrasound transmission and digital signal processing for high accuracy. The ST301 supports three types of transducers: clamp-on, insertion, and flow-cell, offering flexible installation options. Its self-adaptive algorithm ensures optimal performance even with changing liquid properties. The weatherproof metal enclosure provides durability in harsh environments. A built-in LCD and keypad enable easy operation and configuration. The RS485 interface with MODBUS support ensures seamless communication. It offers various I/O options, including batch control and thermal energy measurement. The ST301 delivers zero maintenance and long-term stability. Ideal for industrial and commercial applications, it supports precise flow monitoring in water distribution and fuel consumption.
