Ultrasonic Doppler Flowmeter Ultrasonic Doppler Velocimeter User Manual

　　Part 1: Ultrasonic Doppler Velocimeter

　　Ultrasonic Doppler Velocimeter is a flow measurement instrument based on the acoustic Doppler effect principle. It uses ultrasonic transducers to detect flow velocity with ultrasonic waves. The measurement point is located in front of the probe, without disturbing the flow field. It offers high measurement accuracy and a wide range; it can measure both weak and strong currents; it has high resolution and fast response speed. It also incorporates pressure and temperature sensors to measure water depth and temperature, and transmits flow velocity, water level, and temperature via RS485.

　　Part 2: Ultrasonic Doppler Flowmeter

　　Ultrasonic Doppler Flowmeter collects real-time flow velocity, water level, and temperature from the Ultrasonic Doppler Velocimeter. The instrument is equipped with an LCD display and a Chinese menu for easy operation; it visually displays instantaneous flow rate, cumulative flow, flow velocity, water level, and cross-sectional area of flow. It features RS232 or RS485 communication ports for remote data transmission and a 4–20 mA analog output for online data transmission. The instrument allows input of various parameters based on on-site conditions to calculate the cross-sectional area and water flow rate.

　　Part 3: Ultrasonic Doppler Velocimeter (Flowmeter) (GPRS/NB Wireless Version)

　　Ultrasonic Velocimeter (Flowmeter) is used in conjunction with a GPRS/NB board. The sensor data is transmitted to a server via the GPRS/NB board, then parsed and displayed by an application on the server. Data transmitted by the velocimeter includes water level, flow velocity, temperature, and voltage; data transmitted by the flowmeter includes water level, instantaneous flow rate, cumulative flow, and voltage.
