Technical information

Corrections The Tank Side Monitor can automatically calculate the following corrections:

• Correction for the Hydrostatic Tank Deformation (HyTD)

• Temperature Correction for Thermal Expansion of the Tank Shell (CTSh)

Flow calculation

(in preparation)

The Tank Side Monitor can calculate the approximate flow based on the rate of level change and a linear

conversion, to volumetric flow.

Overfill protection The NRF590 can be configured and used as part of an overfill protection system in comjunction with the

approved WHG operating mode of the Endress+Hauser FMR53x/54x radar devices (as described in the TÜV

test certificate for the FMR53x/54x WHG operating mode).

Overview

• Level input from FMR53x/54x via HART communication

• Discrete output via DO #A and/or DO #B (in conjunction with the AL1 alarm function block

• Analogue 4...20mA output via AO

Note!

AO #2 and DO #C (if available) cannot be used for overfill protection
