Function and system design

The Tank Side Monitor NRF590 is a field device for the integration of tank sensors into tank inventory systems.
It is used in tank farms, terminals and refineries.
Especially, it can be used in connection with Micropilot M level radars (for inventory control) and Micropilot S
high accuracy level radars (for custody transfer applications).
The Tank Side Monitor is typically installed at the bottom of the tank and allows to access all connected tank
sensors. Typical process values measured by the sensors are:
• level
• temperature (point and/or average)
• water level (measured by capacitive probe)
• hydrostatic pressure (for hydrostatic tank gauging, "HTG", or hybrid tank measurements, "HTMS")
• secondary level value (for critical applications)
The Tank Side Monitor collects the measured values and performs several configurable tank calculations.
All measured and calculated values can be displayed at the on-site display. Via a field communication protocol,
the Tank Side Monitor can transfer the values to an inventory control system.
