Product Critical Technical Advantages
-
Engineering excellence in a multipurpose dual-tube design provides the high accuracy and repeatability of Coriolis technology for both liquids and gases. It is specifically engineered to handle standard process conditions with a focus on long-term reliability and low total cost of ownership.
-
Precision engineering for flexible system integration is enabled by the compact dual-compartment transmitter housing. With up to 3 freely combinable I/Os and support for modern Ethernet-based protocols, the E 300 fits seamlessly into diverse control architectures, allowing for one-sided wiring access to simplify installation.
-
Integration of operational intelligence through Heartbeat Technology provides a permanent health check of the device and documented verification without interrupting the process. This diagnostic power ensures measurement reliability and allows plant operators to safely extend recalibration cycles based on actual device performance.
-
Full access to process and diagnostic information is available via integrated WLAN and a backlit display with touch control. Operators can securely perform commissioning, maintenance, and troubleshooting wirelessly or directly at the meter without the need for specialized hardware or opening the housing.
-
Reduced complexity through multi-variable measurement eliminates the need for separate temperature or density transmitters. The Promass E 300 provides mass flow, volume flow, density, and temperature simultaneously, reducing the number of process penetrations and simplifying the overall piping layout.
-
Space-saving installation is guaranteed as the Coriolis measuring principle operates independently of the flow profile. The sensor requires no straight inlet or outlet piping runs, meaning it can be installed immediately after elbows, valves, or pumps without any loss in accuracy.
