The fixed modular ultrasonic flowmeter is widely used for long-term online flow measurement of various liquids. The main unit and sensor are installed separately. The main unit is mounted on a guide rail, and the sensor is mounted on the pipeline to be measured. The main unit and sensor are connected by a dedicated ultrasonic flowmeter cable, enabling flow measurement. It features a compact size, low cost, easy operation, and a comprehensive output interface. It is suitable for batch use, installed in instrument cabinets or distribution cabinets, and is suitable for system integration supporting projects, water conservancy, Flow meters for networked monitoring projects such as water resources or heating systems.
Product features
• Equipped with self-diagnosis function to check if the current working status is normal.
• Supports multiple languages including Chinese, English, and Italian, catering to different user needs.
• Uses different models of sensors suitable for measuring pipeline flow of various diameters, with measurement diameters up to DN6000mm.
• Uses dual-balanced differential transmission and receiving circuits to effectively resist strong interference sources such as frequency converters, TV towers, and high-voltage lines.
• Can be transmitted via RS485 bus, with transmission distances exceeding dry meters. Networking via the MODBUS protocol is very convenient and can meet the diverse needs of different users.
• Equipped with a pair of PT100 temperature sensors to measure the temperature of heating (cooling) pipe supply and return water, enabling real-time monitoring of heat (cooling) quantity, enabling heat (cooling) measurement.
