Product Critical Technical Advantages
-
Unmatched Accuracy for Fiscal Metering: With the optional PremiumCal, the Promass Q delivers an exceptional mass and volume flow measurement error of only ±0.05%. Its density measurement precision of ±0.1 kg/m³ makes it an elite tool for quality control and custody transfer where every drop and decimal point impacts the bottom line.
-
Optimized Performance for Entrained Gas (MFT): Liquids containing air or gas bubbles traditionally cause significant errors in Coriolis meters. The Promass Q utilizes Multi-Frequency Technology (MFT) to actively compensate for these effects in real-time, ensuring reliable and continuous measurement even in aerated fluids or viscous liquids with gas pockets.
-
Low Pressure Loss and High Turndown: The sensor’s unique design minimizes pressure drop across the meter. This allows for a wider usable flow range (high turndown) and reduced energy costs for pumping, while also maintaining a stable zero point for long-term reliability.
-
Heartbeat Technology for Documented Safety: Integrated Heartbeat Technology provides continuous internal diagnostics and documented verification without interrupting the process. This enables operators to verify the meter’s high-precision performance and maintain audit trails for regulatory and fiscal compliance effortlessly.
-
Versatile System Integration and WLAN Access: The Proline 300 transmitter features a compact dual-compartment housing with up to 3 freely combinable I/Os. Its backlit touch display and WLAN access allow for wireless commissioning and operation, enabling technicians to interact with the device from a safe distance or without opening the enclosure.
-
Multivariable Measurement and Compact Footprint: By providing simultaneous data for mass flow, volume flow, density, and temperature, the Promass Q 300 eliminates the need for multiple discrete sensors. Its ability to operate without straight inlet or outlet piping runs allows for significant space savings in dense metering skids.

Field of Application
-
Custody Transfer: The primary choice for fiscal measurement of oils, fuels, and high-value chemicals where extreme accuracy is legally required.
-
Aerated Liquid Applications: Measuring liquids that naturally contain or trap gas, such as ice cream, adhesives, or oils during tank unloading.
-
High-Precision Density Measurement: Used in blending or concentration control where minute changes in density indicate a change in product quality.
-
Loading and Unloading: Ideal for bunkering or tank truck loading where the presence of air is common at the beginning or end of a transfer.
