The fixed split wall-mounted 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 can be wall-mounted, and the sensor is mounted on the pipeline to be measured. The main unit and sensor are connected with a dedicated ultrasonic flowmeter cable to achieve flow measurement. This is currently one of the most widely used ultrasonic flowmeters.
Product features
• High accuracy rating, measurement accuracy better than ±1%.
• Dual power input interfaces, supports DC24V and AC220V.
• 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.
• Can be transmitted via RS485 bus, with transmission distances exceeding a kilometer. 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.
