Product Critical Technical Advantages
-
Remote Transmitter for Maximum Flexibility: The 500 series transmitter can be installed up to 300 meters away from the sensor. This allows the high-precision sensor to be placed in difficult-to-access or hazardous process locations while the control interface and electronics remain in a safe, convenient area for operators.
-
Unmatched Accuracy for Fiscal Metering: Equipped with PremiumCal, the Promass Q 500 delivers an exceptional mass and volume flow measurement error of just ±0.05%. Coupled with a density measurement precision of ±0.1 kg/m³, it ensures that fiscal transactions and quality control processes are based on the most reliable data available in the industry.
-
Multi-Frequency Technology (MFT) for Entrained Gas: Liquids with gas bubbles or air pockets often disrupt standard Coriolis measurements. The Promass Q 500 utilizes advanced Multi-Frequency Technology to actively compensate for entrained gas in real-time, maintaining continuous and highly accurate measurements even in aerated or viscous fluids.
-
Heartbeat Technology for Integrated Verification: This suite provides continuous self-diagnostics and documented, compliant verification without interrupting the process. For custody transfer, this means a permanent, verifiable audit trail of the meter’s health and performance, significantly reducing the risks associated with measurement drift.
-
Advanced Connectivity and I/O Performance: The Proline 500 transmitter supports up to 4 freely combinable I/Os and high-speed Ethernet-based protocols. With integrated WLAN and a built-in web server, technicians can perform commissioning, configuration, and troubleshooting wirelessly from a safe distance.
-
Low Pressure Loss and High Turndown: The sensor’s design is optimized to minimize pressure drop, which is critical for maintaining high flow rates and reducing pumping costs. This architecture also ensures a stable zero point, allowing for high turndown ratios without sacrificing accuracy at lower flow ranges.

Field of Application
-
Fiscal Metering & Custody Transfer: The definitive choice for the legal-for-trade measurement of oils, fuels, and high-value chemicals.
-
Loading and Unloading Operations: Ideal for bunkering or ship-to-shore transfers where entrained air is frequently encountered during pipe stripping or tank emptying.
-
High-End Quality Control: Used in blending and concentration processes where minute changes in density or mass flow directly impact the final product quality.
-
Aerated Liquid Processing: Measuring aerated food products, viscous adhesives, or oils in processes where gas pockets are a known challenge.
