Ключевые технические преимущества продукта
-
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.

Область применения
-
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.
