Product Overview
The TDF acoustic Doppler point current meter uses the principle of ultrasonic Doppler to measure the average flow velocity of the river channel, and at the same time uses the static pressure method to measure the water depth. It automatically calculates the river channel flow rate based on the river channel section, with accurate measurement and strong anti-interference ability.
Application fields:
Flow calculation: rivers and lakes, urban sewage, industrial wastewater, irrigation water
Product Features:
Accurate measurement: Ultrasonic Doppler measurement technology accurately measures characteristic flow velocity, integrates pressure sensors, and can directly measure water depth.
Strong anti-interference ability: digital sensors have strong resistance;
The instrument can provide one isolated RS232 digital interface and one isolated RS485 digital interface, supporting standard Modbus ASCII and Modbus RTU protocols;
Programmable relay output: Any relay can be set to high alarm, low alarm, or timer mode;
L has the function of automatically saving historical data, which can store and query historical data information for 10 years.
Performance indicators:
Range: Flow rate: 0.02~5m/s; Water level: 0~5m, 0~10m;
Accuracy: Flow rate: 2% ± 1cm/s of reading; Water level: ± 0.5% FS reading
Temperature: Sensor: 0 ℃~60 ℃; Transmitter: -10 ℃~55 ℃;
