- Handheld terminal ADV ultrasonic Doppler flowmeter
Doppler flow meter brings you professional service,the flow velocity measurement of this product is based on the principle of acoustic Doppler effect: when ultrasonic waves are incident on water, scattering bodies (such as suspended particles, bubbles, microorganisms) in the water scatter the sound waves. Due to the presence of water flow, there is relative motion between the scattering bodies and the transmitter and receiver, and the received signal has a certain frequency offset relative to the transmitted signal, which is the Doppler frequency shift. The frequency shift value is related to the flow velocity.
Doppler FLOW METER brings you professional service,characteristics of portable intelligent terminal products:
(1) Output: 4G wireless output, supports OTA remote upgrade
(2) Display: Chinese full-color LCD display, real-time waveform display chart
(3) Battery life: When connected to an external Doppler flowmeter, it works for 4-8 hours on full charge, without 4G wireless output, longer battery life, supports external power bank charging, and battery life is worry free
(4) Scope of use: It can be connected to various sensors such as pH, turbidity, and Doppler current meters.
(5) Usage features: The sensor can be configured with all parameters, the built-in boost circuit can also supply 12V power to the sensor, the operation is convenient, the response is sensitive, and it is suitable for use in outdoor places such as the wilderness.
