Intuitive RGB Display
The built-in RGB LCD screen provides immediate visual feedback on system status:
-
Green: Normal operation
-
Blue: Menu and configuration mode
-
Red: Alarm trigger, fault, or low battery
Benefit: Instant clarity for operators and engineers — no guesswork, no delay.
Configurable Digital Inputs
Niv-X includes two configurable digital inputs that can be used to connect:
-
A high-level float switch for tank overfill protection
-
A bund sensor to detect containment breaches
Benefit: Enhances safety and environmental compliance with real-time alerts.
Remote Alarm Capability
The unit provides a configurable relay output, which can trigger a local or remote alarm device, such as a beacon or sounder.
Benefit: Ensures critical events are clearly flagged, wherever they're needed.
Advanced Sensor Compatibility
Niv-X supports a range of sensor types to suit different tank contents and environments:
-
0–5V Submersible Pressure Sensor: Included as standard. Accurate level readings, matched to your tank size.
-
Optional 4–20mA Input: Use with non-contact radar or ultrasonic sensors for corrosive, aggressive, or hazardous liquids.
-
RS485 Modbus RTU: Ready for integration into SCADA, BMS, and industrial control systems.
Benefit: Flexible, future-proof monitoring for everything from diesel to chemicals.
Cloud Connectivity with Site Easy II
For remote access and analytics, pair the Niv-X with our Site Easy II communication gateway. This transmits data to the Site Info cloud platform for secure, 24/7 online monitoring.

Frequently Asked Questions
Q: What types of liquids can the Niv-X measure?
A: When used with a compatible sensor, the Niv-X can measure a wide variety of liquids, including water, oil, diesel, and various chemicals. The 0-5V Submersible Pressure Sensor option is ideal for water, oil, and diesel, while the 4-20mA input mode allows for use with ultrasonic or radar sensors for more aggressive media.
Q: Can the Niv-X be used in hazardous environments?
A: The Niv-X control unit itself is not ATEX-rated and should not be installed directly in explosive or hazardous zones. However, thanks to its 4–20mA input and RS485 Modbus support, it can be connected to intrinsically safe sensors (e.g. ATEX/IECEx-certified ultrasonic or radar level sensors) that are suitable for hazardous environments. This allows safe monitoring of tank contents from outside the hazardous zone. Always check the sensor manufacturer's certifications to ensure compliance.
Q: How do I install the Niv-X?
A: Niv-X is designed for quick and simple installation. It can be powered by a 9V battery for portable or off-grid applications, or connected directly to 240V mains via its integrated onboard transformer. Installation guides and wiring instructions are included in the product manual.
Q: What kind of alarms can I set up with the Niv-X?
A: Niv-X includes two configurable digital inputs for float switches or bund alarms, and a relay output that can trigger external beacons, sounders, or building alarms. The RGB screen also provides visual alerts, turning red in the event of a fault, alarm, or low battery.
Q: What sensors are compatible with Niv-X?
A: Niv-X supports:
-
0–5V submersible pressure sensors (standard)
-
4–20mA sensors (e.g. ultrasonic, radar, pressure)
-
RS485 Modbus sensors for integrated monitoring
