The client needed a dependable way to monitor solvent levels across a storage tank divided into seven individual compartments, each containing a different product. They required a turnkey, high‑accuracy level indication and alarm monitoring system that would give operators clear visibility, reliable alarms and seamless integration with their wider site network.
To meet this, we built the system around Nivelco Nivotrack magnetostrictive ATEX level probes, chosen for their precision and suitability for hazardous solvent environments. These probes provide continuous level measurement for all seven compartments and feed real‑time data into a purpose‑built local control panel. The panel was designed to give operators everything they need at a glance, including:
- Display indicators for each compartment
- Automatic ullage calculation
- Alarm indicators for high‑level and bund‑full conditions
- Local alarm lamps and an external sounder/beacon
- A full test and mute facility
- ATEX‑certified inputs from all level probes
To strengthen safety further, high‑level and bund‑full detection is handled by Afriso EMA ATEX thermistor switches, ensuring fast and reliable alarm activation whenever levels approach critical thresholds. Alongside local signalling, the system retransmits all level and alarm data via an RS485 loop, allowing integration with external monitoring or SCADA systems.
The completed installation gives the client a robust, high‑accuracy monitoring setup that simplifies daily checks, improves operator awareness and ensures reliable communication across the site — all delivered as a turnkey package tailored to the demands of multi‑compartment solvent storage.
