E+H Promass E 300 Coriolis Flowmeter

The Endress+Hauser Proline Promass E 300 represents a benchmark in industrial process measurement, engineered to serve as a cost-effective multipurpose alternative to conventional volumetric flowmeters. Operating on the proven Coriolis measuring principle, this advanced Coriolis mass flowmeter directly detects mass flow, fluid density, and medium temperature with exceptional accuracy, remaining entirely unaffected by changes in fluid viscosity, pressure, or flow profile.

Designed for versatility, the Promass E 300 handles standard liquid and gas applications seamlessly. Its robust bent dual-tube sensor geometry ensures long-term operational stability and repeatability. Operators benefit from a compact dual-compartment housing equipped with up to three freely configurable inputs and outputs (I/Os), supporting current outputs (HART), pulse/frequency/relay outputs, and digital communication protocols.

For enhanced operational safety and asset management, the device features an integrated web server accessible via an Ethernet service interface (CDI-RJ45) or an optional WLAN access point, allowing users to configure parameters, view diagnostic messages, and perform data management directly using standard web browsers or smart mobile tools like the SmartBlue app. Furthermore, built-in Heartbeat Technology enables comprehensive device self-monitoring and traceable verification without interrupting the ongoing process. Space-saving installation is easily achieved as the meter requires no specialized inlet or outlet runs, making the Endress+Hauser Promass E 300 the ideal choice for accurate, reliable, and multi-variable industrial flow measurement.

FAQ

Q1: Does this flowmeter require straight inlet and outlet pipe runs for accurate measurement? A: No. The Promass E 300 operates on the Coriolis principle, making it immune to flow profile distortions. It allows for space-saving installation with no straight inlet or outlet run requirements.

Q2: What variables can this device measure simultaneously? A: It provides simultaneous, multi-variable measurement of mass flow, volume flow, corrected volume flow, density, and medium temperature.

Q3: How can I access and configure the device parameters locally or remotely? A: Local configuration can be performed via the 4-line backlit display with touch control. Remote operation and configuration are supported via a web browser (using the integrated web server via CDI-RJ45 or optional WLAN) or asset management tools like FieldCare and DeviceCare.

Q4: Is it suitable for measuring gas applications? A: Yes. Depending on the version ordered, the device is designed for the accurate flow measurement of both liquids and gases, and includes advanced features like the Gas Fraction Handler to maintain measurement stability under two-phase flow conditions.
