NRF81 Tankside Monitor
The NRF81 Tankside Monitor (TSM) is used in combination with Varec radar gauges for bulk storage applications at tank farms, terminals and refineries. It is designed to integrate and collect tank gauging data and provide detailed information for storage and process applications.

Operational Process
The NRF81 TSM is typically installed at the bottom of the tank for ease of access and allows access to all connected tank sensors. collects the measured values and performs several configurable tank calculations. All measured and calculated values can be displayed at the on-site display. Also, through a field communication protocol, the NRF81 TSM can transfer the values to an inventory control system like FuelsManager.
Easy to Read, Safe and Simple to Operate
Mounted within a flameproof enclosure,the NRF81 TSM has a Liquid Crystal Display (LCD) with touch control that ensures safe operation even in hazardous areas.
Versatile Tank Gauging
In addition to connecting to the primary radar tank gauge, the NRF81 TSM also integrates HART® compatible devices using intrinsically safe connections, such as temperature and pressure transmitters for hybrid and hydrostatic (mass) applications.
Accurate Results
The NRF81 TSM fulfills the exacting demands of tank inventory management, inventory control, custody transfer, loss control, total cost saving, and safe operation. For volume calculation it will accept an input from either an average temperature probe 453x ATC series of temperature devices (via twisted pair cables, HART protocol) or via spot temperature element (via 2/3/4-wire RTD signal).
Worldwide Approvals
The NRF81 TSM is approved for use in explosion hazardous areas to ATEX, FM and IECEx standards.
