The HyQuest Solutions Point Velocity Display PVD100 is a small electronic device for measuring flow velocity from almost any mechanically rotating current meter. It shows the velocity on its LCD directly in m/sec or ft/second. To calculate discharges, serial data can be transmitted to an external computer. A very important feature is the automatic detection of signal shorts accompanied by an alarm to the operator who may decide on repeating the measurement. All important settings are saved in memory, eliminating the burden of re-configuring the device when the unit is turned back on.
The PVD100 does not need to be connected to an external device to operate. The visual indicators, LCD and internal buzzer can be used to make a conventional current meter measurement and to compute water velocity.
Cleaning signals and avoiding noise
The PVD100 cleans the signal from a mechanically rotating current meter such as a Price AA, HS OSSB1 or HS OSS-PC1 meter. Thereby, miscounting and double counting are avoided.
Connectivity
The PVD100 offers connectivity between the current meter and a hand-held computer using either a connecting lead or an optional Bluetooth® wireless interface. It can be mounted directly onto a top-setting wading rod. Faulty connections are detected. Commands for performing a measurement and making operating selections can be sent.
Extended Measurement Range
The PVD100 can operate in two different velocity range modes supporting both typical and extremely slow rotating current meters (see Technical Specifications).
Direct velocity reading
Digitally processes and cleans signals from catwhisker and magnetic head meters
