Enhance Process Insight and Accuracy
Multivariable measurement capability enhances operations by measuring static and differential pressure and temperature in a single device. With a variety of options, these devices include Ultra for Flow performance class, Callendar-Van Dusen sensor matching, extended range sensor and a selection of protocols. Multivariable transmitters allow you to limit pipe penetrations, reduce wiring costs and reduce installation time.
Best-in-class measurement
Multivariable solutions help enhance performance. Features include Ultra for Flow (+/- 0.04% of reading specification) for high accuracy in flow measurement and Callendar-Van Dusen (CVD) sensor matching, which uses CVD constants to increase RTD measurement accuracy up to 70%.
Measurement configurations
Featuring eight different measurement options, Multivariable solutions are able to meet a wide range of application requirements. These devices can provide singular or a combination of measurements, including differential pressure, static pressure and process temperature available in Coplanar™ and In-Line platforms. For reliable and accurate measurements in harsh environments, Multivariable technology also offers the all-welded, hermetic design of the SuperModule™ Sensor.
Installation & commisioning
Ready-to-install, Multivariable technology provides preconfigured and calibrated devices. Additionally, software packages, such as the Rosemount™ Engineering Assistant Software offer a simple communication and configuration interface for Rosemount mass flow transmitters. To configure a variety of Rosemount pressure, temperature, level and flow products, Rosemount Transmitter Interface Software is also available.
Fully-assembled DP flow
As a fully-assembled DP flow solution, a Multivariable flowmeter features a variety of advantages for flow measurement. Capable of calculating mass flow from the transmitter, this device is delivered pre-configured and pre-ranged for easy installation and commissioning. Factory-assembled and tested, these DP Flow devices are also leak-checked before shipment, ensuring reduced leak points for optimal performance.
Protocols
Multivariable transmitters feature communication protocol options that incorporate seamlessly into your existing infrastructure. Wired alternatives include industry-standard HART®, FOUNDATION™ Fieldbus and Modbus® protocols. For a wireless solution, WirelessHART® is a self-organizing network that delivers >99% data reliability and provides access to previously inaccessible areas.
