Digital Doppler flow meter RS485 for the measurement of fluid velocity
The digital doppler flow meter uses the ultrasonic Doppler principle to measure the flow velocity, the ultrasonic time difference method measures the liquid level and calculates the flow rate by setting the cross-section. DRFN’s DUC2-DPL controller can measure the instantaneous flow and accumulated flow, the range of the flow velocity is from 0.01 to 10 m/s.
Advantages Of The Doppler Flow Meter
1. A universal Doppler controller specially designed for DRFN series Doppler flow digital sensors, compatible with all DRFN Doppler flow digital sensors;
2. The Doppler flow meter will collect high-precision data more stably in a special encrypted communication method;
3. The working status of the sensor can be queried by the controller, including reading the serial number of the sensor;
4. Support a variety of installation methods, the protection grade is IP66, can work continuously for a long time in harsh environments;
5. Provide two power supply modes of AC and DC, both of which are wide-voltage power supply;
6. A two-wire RS485 interface, support Modbus RTU communication protocol;
7. Menu password can be set to facilitate hierarchical management.
