STK-590 Radar Level Gauge

Product Description

590 Radar Level Gauge delivers ±0.5 mm (0.020 in.) instrument accuracy, reducing level measurement uncertainty to a minimum. It enhances your storage operation by providing certified custody transfer accuracy, better inventory management and reliable loss control data.
 590 is normally combined with high precision multi-spot temperature sensors for highest accuracy API standard net volume calculations.


Get highest certified custody transfer accuracy for precise asset management of bulk liquid storage.
Achieve higher safety with third party certified IEC 61508 SIL 2 or SIL 3 capability.
Use one tank opening to install the 2-in-1 gauge for either redundant level measurements or to achieve independent safety and level measurement systems.
Benefit from convenient and safe installation with two-wire IS bus power supply.
Include wired and/or wireless data transmission.
Measure in all bulk storage tank types and products, ranging from liquefied gases, light products, crude oil and bitumen.
