A9. The brochure says that WaveRadar measures at 10Hz but outputs data at 210Hz
with a default of 4Hz. Please explain this.
A:
There are two independent processes, involving two independent processors located
within the WaveRadar electronics module. The first is the measuring cycle (sampling
duration) which operates at a fixed 10Hz. The other is the control and communication
process that acquires values from the measuring cycle buffer and outputs the data at 2
10Hz, with a default set at 4Hz.
A10. How can the data output be changed from 4Hz?
A: The data output rate may be set from 2 to 10Hz in steps of 2ms by RS Aqua before
delivery. Such a requirement must be specified at the time of order placement.
A11. After each distance measurement is made, is any filtering applied?
A. No. The output from the sensor is a pure mean of all the measurements taken by the
radar during the measurement cycle. Any filtering of data and all tide and wave processing
will be performed by the processing software (WaveView).
A12. Where is the datum point for the distance measurement?
A: It is at the point where the main sensor housing mates with the TRL/2 adapter. This
coincides with the lowest end of the wave guide. The operating manual provides
confirmation.
A13. How portable is WaveRadar Rex?
A: WaveRadar Rex may be dismantled into two sections. The sensor head assembly
weighs 14kgs and the antenna dish assembly 11kgs.
A14. Can WaveRadar measure directional wave data?
A:
Not directly although system integrators have achieved directional measurements via
the installation of multiple WaveRadar sensors.
A15. The Rosemount Tank Radar web site describes the communication on a TRL2
bus and 8 to 10 or up to 16 units can be on one TRL2 bus. Do we need a Field
Communications Unit (FCU) and FBM if we are operating just one WaveRadar?
A:
No. The FCU is only used with Tank Radar. The FBM is supplied and is all that is
required.
