FlowShark HV
The new FlowShark HV from ADS is a hand held velocity meter utilizing ultrasonic Doppler technology. It is designed to be used in any open channel including wastewater collection pipes, irrigation channels, and streams. The unique application of ultrasonic Doppler technology gives the FlowShark HV advantages over magnetic sensors and propeller meters.
The ultrasonic sensor transmits a narrow high-frequency sound pulse along its horizontal axis. The sound pulse is reflected back to the sensor by particles and entrained air in the medium. These reflected echoes will be at a higher frequency than the transmit frequency in proportion to their velocity.
The return echoes are precisely timed in order to isolate the measurement window at a point directly in front of the sensor face. It is this breakthrough in technology that allows Doppler technology to operate in a point velocity mode.
The FlowShark HV adjusts for differences induced by water temperature using a built in temperature probe. The frequency spectrum is then processed digitally to translate frequency data into a highly accurate velocity measurement.
The FlowShark HV has a broad range of applications for anywhere that a point velocity measurement is required. Some common applications are:
-
Calibrations of flow meters, weirs, and flumes
-
Velocity profiles of streams and rivers
-
Spot checks of flow velocities in irrigation channels
