Product Critical Technical Advantages
-
Engineering excellence in a cost-effective dual-tube design provides high-accuracy measurement for liquids and gases without the premium price of specialized alloy sensors. It is designed to be the workhorse of the process industry, offering long-term stability and reliability in diverse environments.
-
Precision engineering for space-saving integration utilizes the ultra-compact 100 transmitter housing. This design allows for full functionality in a package that fits into the tightest clusters, which is essential for modern modular skids where every centimeter of piping counts.
-
Integration of operational intelligence through Heartbeat Technology enables continuous internal diagnostics and documented verification of the sensor health without interrupting the process. This proactive monitoring ensures measurement reliability and helps extend the intervals between formal calibrations.
-
Robust immunity to process conditions allows the Promass E 100 to operate independently of fluid properties such as viscosity or density. The balanced dual-tube sensor naturally resists external pipe vibrations, ensuring that the control system receives stable and accurate mass flow data.
-
Time-saving local operation via the integrated web server allows for rapid commissioning and maintenance without the need for additional software or proprietary hardware. Operators can securely access the device using a standard web browser, simplifying field service tasks.
-
High ingress protection with an IP69 rating ensures the device remains fully operational even in environments subject to high-pressure washdowns or aggressive ambient conditions. This makes the Promass E 100 suitable for both general industrial and more demanding washdown-heavy production areas.
