EVO 1610

The EVO 1610 Microwave Radar Gauge delivers highly accurate, non-contact level measurement for terminal operators, refinery engineers, custody-transfer specialists, and EPC project teams.
The gauge provides 0.5 mm custody-grade accuracy and OIML R85 certification, ensuring audit-ready measurements for storage tanks and inventory management.
Unlike traditional pulse radar or servo gauges, the EVO 1610 uses 10 GHz Frequency-Modulated Continuous Wave (FMCW) radar technology. This allows it to deliver stable, drift-free level readings that are not affected by vapor, foam, agitation, or temperature changes.
With infrared remote calibration and multi-protocol communication capabilities, the EVO 1610 simplifies commissioning, reduces maintenance downtime, and provides long-term operational reliability for tank gauging applications worldwide.

EVO 1610 Radar Level Gauge

Applications

Custody Transfer: Accuracy of ±0.5 mm provides precise, traceable volume data for fair trade measurement and reliable inventory reconciliation.
Challenging Liquids: FMCW radar technology penetrates vapor and foam, delivering stable measurements even in turbulent or foamy storage conditions.
Corrosive Storage: The non-contact radar design with a PTFE-sealed antenna minimizes fouling and extends gauge life in aggressive chemical environments.
Process Monitoring: Multi-protocol communication enables real-time inventory tracking, diagnostics, and integration with DCS, PLC, and SCADA systems.

Why is the EVO 1610 considered custody-grade?

−

The evo1610 achieves 0.5 mm accuracy and holds the OIML R85-1 & R85-2 certification. This official certification, combined with its high resolution, verifies that the measurement integrity is sufficient for high-value commercial transactions, reducing financial disputes and simplifying regulatory audits.

How does FMCW technology outperform traditional pulse radar in challenging conditions?

FMCW (Frequency-Modulated Continuous-Wave) constantly transmits and processes a signal via frequency shift, which provides a much stronger and more stable measurement than the intermittent reflection used by pulse radar. This allows the EVO 1610 to penetrate foam and ignore vapor density changes while maintaining accuracy, especially important in agitated process vessels.

Can the gauge be configured without opening the housing?

Yes. The evo1610 is designed for safety and efficiency. Configuration and diagnostics are performed using the MCG 2150 Infrared Remote Calibrator. This allows field technicians to communicate wirelessly with the gauge from the ground, ensuring the explosion-proof seal remains intact and enhancing worker safety.
