Description

What is NRF81?

  • The NRF81 Tankside Monitor (sometimes called Tankside Monitor NRF81 or simply “NRF81”) is a field device / gateway used in tank gauging systems, especially for bulk storage tanks (e.g. in terminals, refineries, tank farms).
  • Its role is to integrate, monitor, and relay data from various sensors on a tank (level, temperature, pressure, etc.) to higher-level inventory or control systems.
  • It is commonly used in custody transfer or inventory control applications (i.e. measuring and accounting for the volume/mass of fluid in the tank).

Key Functions & Capabilities

Here are some of the main functions and features of NRF81:

Feature

Description

Sensor integration

Can connect to radar gauge, temperature probes, pressure transmitters, etc.

Tank calculations / corrections

Performs volume, density, or level corrections (e.g. to account for temperature or tank deformations)

Alarm outputs / relays

Has multiple SIL-rated relay outputs for alarms or safety functions

Communication interfaces

Supports several protocols: Modbus RS-485, V1, HART, analog 4–20 mA outputs, etc.

Safety & approvals

Designed for use in hazardous areas, with explosion protection and compliance with safety standards (e.g. SIL2 / SIL3)

Enclosure & robustness

Rugged enclosures (e.g. IP66 / IP68, NEMA 4X / 6P) to handle harsh conditions

User interface & display

Has local display (LCD) and touch control (in safe version) to show measured/calculated values on site.

Technical / Performance Highlights

  • Supports SIL2 (and in some redundant/homogeneous setups, SIL3) safety levels.
  • Up to 6 relay outputs for alarms and safety functions.
  • Wide range of output options: analog, HART, digital (Modbus, V1).
  • Operating / ambient temperature range: typically –40 °C to +60 °C
  • Power supply: AC 85–264 V (often)
  • Intrinsically safe (i.s.) power/communications to connected field sensors in hazardous zones.
