Modbus Doppler Flow Controller Remote Assistance For Open Channel
A universal Doppler flow controller specially designed for DRFN series digital Doppler flow sensors to realize the measurement of fluid velocity. The instrument uses the ultrasonic Doppler principle, suitable for flow rate measurement of open channels and partially filled pipes. The measurement range of the flow velocity is from 0.01 to 10 m/s.
Advantages Of The Doppler Flow Controller
RS485 Modbus RTU
RS485 allows multiple devices to be connected to the same bus and perform data transmission and control through serial communication protocols, making the integration between devices simpler and more flexible.
RS485 uses differential signal transmission, which can resist electromagnetic interference in industrial environments and ensure stable data transmission.
RS485 can support relatively long communication distances, allowing devices to be distributed in distant locations while maintaining reliable communication.
2 SPST multifunctional relays, 2 high-precision 0/4~20mA current output, a two-wire RS485 interface. Satisfy monitoring, control, and remote data transmission.
128*64 large screen graphic dot matrix LCD screen, Chinese and English language to set. Doppler flow controller has clock and historical data recording functions to meet higher data management requirements.
Support a variety of installation methods, can be applied to more different installation environments.
