Table C-5: List of Input Registers to the User Defined Variable
Variable
Register
Description
Min Electronics
Temperature
20146
Minimum electronics temperature measured by the
device (°C)
Max Electronics
Temperature
20148
Maximum electronics temperature measured by the
device (°C)
Min Signal Quality
21034
Minimum signal quality measured by the device since
last signal quality reset. Signal quality calculation must
be enabled to use this variable.
Max Signal Quality
21036
Maximum signal quality measured by the device since
last signal quality reset. Signal quality calculation must
be enabled to use this variable.
Distance to Upper Surface 21042
Distance to the upper product surface (m) when
measuring on multiple products in the tanks. Double
Surface function must be enabled to use this variable.
Distance to Lower Surface 21044
Distance to the lower product surface (m) when
measuring on multiple products in the tanks. Double
Surface function must be enabled to use this variable.
Surface Signal/Noise Ratio 21054
Ratio between surface echo signal strength and signal
noise (dB). A high value (>20 dB) indicates very good
margin to noise.
Product Dielectric
Constant
22800
Square root of the product dielectric constant
estimated by the transmitter when the Bottom
Projection function is enabled.
The product dielectric constant is calculated when both
the bottom and surface echoes are found by device,
and when surface echo is within the Max Projection
Distance. Product dielectric constant estimation is
frozen if any of these conditions are not fulfilled.
Unit
Units of measurement of the user defined variable.
More advanced options
More advanced options are only available in Rosemount Radar Master Plus.
By default, these parameters are automatically set based on current configuration. It is
recommended that these parameters should remain at the default settings, unless there is
a good understanding of the function and capability of the parameters.
Empty tank handling
The Empty Tank Handling functions handle situations when the surface echo is close to the
tank bottom.
