The SITRANS FUS380 Water Flow Monitor is an ultrasonic flowmeter designed for accurate water flow measurement in utility applications.
It operates using a 2-path ultrasonic measuring principle to ensure high precision and reliability.
The device can be powered by either battery or mains supply, offering flexible installation options.
It is widely used in district heating, cooling systems, and general water distribution networks.
The flow monitor features a digital display that shows measurement values and diagnostic information.
It includes an IrDA optical interface for communication and easy configuration via SIMATIC PDM software.
Optional communication modules such as RS232 and RS485 with MODBUS RTU are available.
The device provides high accuracy (around ±0.5% of flow rate) with excellent long-term stability.
Its design allows measurement of various water qualities without pressure loss in the system.
Overall, it delivers reliable and efficient water flow monitoring for industrial and municipal applications.
The SITRANS FUS380 is a 2-track, ultrasonic flow monitor designed for accurate, long-term monitoring of water in district heating plants, local networks, boiler stations, and chiller plants. It is a versatile meter that can be battery or mains-powered, providing bidirectional measurement without causing pressure drops in the system.
