Promass E200


Promass E200

Coriolis mass flowmeter with true 2-wire technology (4-20mA)

By using state of the art low power electronic components, Endress and Hauser succeeded in combining the accuracy and repeatability attributed to Coriolis technology with the cost and safety benefits of 2-wire devices.  With line sizes in DN8 to DN50, Promass E 200 simultaneously measures the mass flow, fluid density and temperature across a range of liquids and gases offering outstanding accuracy and repeatability for improves process control.

Features and Benefits

-    Reduced installation and wiring costs
-    Maintenance free
-    Simultaneous measurement of mass, density, volume and temperature
-    Immune to pipe vibrations


The Promass E 200 offers continuous process control and easy integration.
Suitable for highly accurate measurement of liquids and gases.
Coriolis measuring principle operates independently of fluid physical properties and is unaffected by process influences - i.e. stable under varying process conditions (e.g. pressure or density).
