Mass Measurement


Proline Promass Q 300/500

February 2018 Mass Measurement

Whether in custody transfer or meeting stringent product quality requirements, superior measuring accuracy is essential in many industrial applications. Historically, high accuracy levels were only achievable under ideal circumstances, meaning stable process conditions and true single-phase homogeneous fluids. In the real world, however, these ideal conditions do not often exist. The Promass Q Coriolis flowmeter has been developed exactly for such applications in the food as well as the oil and gas industries.

Promass Q guarantees unmatched accuracy for mass flow, volume flow and density determination under frequently changing process conditions for:

• Highly accurate fluid density and concentration determination for product quality in the food industry.

• Highest accuracy and repeatability for custody transfer in mass or volume units in the oil and gas industry.

Multi-frequency technology for fluids with entrained gas

Measurement errors, no matter whether they are due to desired or unintentional air entrainment, are now a thing of the past. Promass Q, with its revolutionary multi-frequency technology (MFT) allows a real-time and active compensation of measuring errors due to fluids containing suspended bubbles or even micro bubbles.

The MFT allows an accurate measurement of various gas entrained fluids such as:

• Ice cream, cream cheese, milk, honey, jam, etc.

• Viscous heavy crudes, gas-saturated fluids, etc.

Additional benefits include:

• Exceptional density measurement performance.

• Wide useable flow range.

• Superior repeatability.

• Low sensitivity to changing process pressure/temperature.

• Small and light.

Transmitter technology for seamless system integration

Promass 300/500 makes no compromises in performance and accuracy. Digital signal processing starts right at the intelligent sensor and is the base for a truly multivariable measuring device: Mass flow, volume flow, density and temperature can be measured with one single sensor. With its variety of digital protocols (EtherNet/IP, Modbus RS- 485, Profibus DP, Profinet, FF, HART and WirelessHart) as well as freely configurable analog outputs, Promass Q 300/500 fulfils all expectation for seamless system integration.

Heartbeat Technology: feeling the pulse of a process

The onboard diagnostics and Heartbeat Technology ensure maximum product and process safety, allowing sensor, measuring tubes and electronics to be verified without process interruption. In the case of a sensor or electronic problem, text remedy instructions are provided. The data handling concept (HistoROM) makes the exchange of spare parts easy and reduces downtime, while calibration data and transmitter parameters are stored and automatically reloaded after a maintenance event.

Wireless access to all device data

The Proline 300 dual chamber housing eliminates the need to open the electronic housing during commissioning. For parameter changes or troubleshooting the web server allows the user to connect with the device through a standard laptop computer either via cable or wirelessly with any WLAN enabled device, without any additional tools or software. Furthermore, a fully graphical display with touch control, either built-in or remote, is available for full field access.
