Material die-cast aluminum
Fixed split wall-mounted ultrasonic flowmeter is widely used for long-term online flow measurement of various liquids. The host and sensor are installed separately. The host can be wall-mounted. The sensor is installed on the pipe to be measured. The host and sensor are connected with a special ultrasonic flowmeter cable to achieve flow measurement. It is currently the most widely used ultrasonic flowmeter.
Features

• Dual power input interface, DC24V and AC220V available.
• Equipped with self-diagnosis function to prompt whether the current working status is normal.
• Supports multiple languages such as Chinese, English, and Italian, suitable for the needs of different users.
• Select different types of sensors, suitable for measuring the flow of pipes with different diameters, and the measuring diameter can reach DN6000mm.
• It can be transmitted through the RS485 bus, and the transmission distance can reach more than one kilometer. The MODBUS protocol is very convenient for networking and can meet the various requirements of different users.
• Equipped with a pair of PT100 temperature sensors to measure the supply and return water temperatures of the heating (cold) pipelines and monitor the heat (cold) quantity in real time, the heat (cold) quantity measurement function can be realized.
