Endress+Hauser Proline Promass E 200 Coriolis Flowmeter
The Endress+Hauser Proline Promass E 200 is a cost-effective, multipurpose Coriolis flowmeter designed for accurate measurement of liquids and gases across a wide range of standard process applications. As a genuine loop-powered Coriolis flowmeter, it provides a practical alternative to conventional volumetric flowmeters while reducing installation complexity and overall cost of ownership.
The Promass E 200 uses the Coriolis measuring principle to provide direct mass flow measurement while simultaneously measuring other process variables such as density, temperature and volume flow. This multivariable capability can reduce the number of individual measuring points required in a process system.
Cost-Effective Coriolis Measurement
Promass E 200 is designed as a mid-range, multipurpose Coriolis flowmeter for standard industrial applications.
It provides accurate measurement of both liquids and gases and can serve as an alternative to conventional volumetric flowmeters where direct mass flow measurement and additional process information are required.
Its combination of Coriolis measurement, loop-powered operation and integrated diagnostics makes it suitable for users looking to balance measurement performance with installation and operating costs.
Accurate Liquid and Gas Flow Measurement
Promass E 200 provides measurement accuracy of:
Liquid mass flow: ±0.25% standard
Liquid volume flow: ±0.25%
Gas mass flow: ±0.50%
Liquid density: ±0.0005 g/cm³
The flowmeter supports measurement of:
Mass flow
Volume flow
Corrected volume flow
Density
Reference density
Temperature
This makes Promass E 200 suitable for process monitoring where several measurement parameters are needed from one instrument.
Compact Dual-Tube Sensor
The Promass E 200 uses a compact dual-tube Coriolis sensor designed for reliable measurement in standard industrial applications.
The nominal diameter range is DN8 to DN50 (3/8 to 2"), with a measuring range of up to 70,000 kg/h (2,570 lb/min).
The measuring tube is manufactured from 904L stainless steel, with 316/316L stainless steel used for the process connections, depending on configuration.
Loop-Powered Technology
One of the most important characteristics of Promass E 200 is its genuine loop-powered transmitter.
Loop-powered operation simplifies electrical installation by using the existing current loop for device power and communication. This makes the instrument particularly attractive for standard process measurement applications where straightforward wiring and minimized installation costs are important.
Space-Saving Installation
The Coriolis measuring principle allows Promass E 200 to be installed without conventional inlet and outlet straight pipe runs.
This provides greater flexibility when installing the flowmeter in compact process piping and can help reduce the overall space required for the measurement point.
Process Pressure and Temperature
Promass E 200 is designed for standard and demanding process environments.
Key process specifications include:
Process pressure: up to 100 bar (1450 psi), depending on configuration
Medium temperature: -40 to +150 °C (-40 to +302 °F)
Nominal diameter: DN8 to DN50
Measuring range: up to 70,000 kg/h
This makes the flowmeter suitable for a broad range of industrial liquid and gas measurement applications.
Convenient Transmitter Operation
The Promass E 200 transmitter features a separate connection compartment, making device wiring more convenient.
The instrument is equipped with a display featuring touch control and background lighting, allowing users to operate the device without opening the housing. This improves operational convenience and supports safer device interaction in industrial environments.
Heartbeat Technology
Promass E 200 incorporates Endress+Hauser Heartbeat Technology, providing integrated verification and diagnostic functions.
Heartbeat Technology allows users to verify measurement performance and monitor device condition without removing the flowmeter from the process. This can support preventive maintenance, measurement reliability and improved plant availability.
Safety and Approvals
Promass E 200 is available with worldwide plant safety approvals, including SIL and hazardous-area approvals, depending on the selected configuration.
The instrument also offers hygienic approvals and certificates such as 3-A, EHEDG and cGMP, making applicable configurations suitable for hygienic process environments.
