Endress+Hauser Proline Promass S 500 Coriolis Flowmeter
The Endress+Hauser Proline Promass S 500 is a hygienic Coriolis flowmeter designed for demanding Food & Beverage applications where accurate measurement, optimal cleanability and installation flexibility are essential. Its self-drainable single-tube system provides a hygienic measurement solution, while the remote transmitter architecture offers flexible installation and convenient access to process and diagnostic information.
Hygienic Coriolis Flow Measurement
Promass S 500 provides reliable measurement of mass flow, volume flow, density and temperature from a single measuring point. The Coriolis measuring principle operates independently of physical fluid properties such as viscosity or density.
Key measurement performance includes:
Liquid mass flow accuracy: ±0.10%
Liquid volume flow accuracy: ±0.10%
Liquid density accuracy: ±0.0005 g/cm³
Measuring range: 0 to 70,000 kg/h
Medium temperature: -50 to +150 °C
Maximum process pressure: PN 40 / Class 150 / 20K
Self-Drainable Single-Tube Design
A key feature of Promass S 500 is its fully self-drainable single-tube measuring system.
The easy-to-clean tube design helps reduce product residue and supports efficient hygienic processing. It is particularly suitable for production environments where frequent cleaning and drainage are required.
The design also supports space-saving installation without conventional inlet and outlet straight pipe runs, simplifying installation in compact process systems.
Designed for Food & Beverage Applications
Promass S 500 is specifically designed for hygienic applications in the Food & Beverage industry.
Typical applications include:
Food processing
Beverage production
Dairy processing
Liquid food ingredients
Hygienic liquid transfer
Sanitary process measurement
CIP/SIP systems
Food and beverage processing skids
The flowmeter supports hygienic requirements through a wide range of sanitary process connections and 3-A, EHEDG and cGMP conformity.
Fast CIP/SIP Recovery
Promass S 500 is designed for fast recovery from CIP and SIP processes, making it suitable for production environments where cleaning and sterilization are performed frequently.
This helps reduce process interruption and supports efficient hygienic production operations.
Remote Transmitter with Up to 4 I/Os
The main advantage of the Promass S 500 compared with the compact transmitter versions is its remote transmitter configuration.
The remote version provides:
Up to 4 configurable I/Os
Flexible fieldbus communication
Access to process and diagnostic information
Backlit display
Touch control
WLAN access
Flexible transmitter installation
Standard cable connection between sensor and transmitter
This architecture allows the sensor and transmitter to be positioned separately, providing greater installation flexibility in hygienic process plants.
Flexible Communication and System Integration
Promass S 500 supports a broad range of communication technologies for integration with modern automation systems.
Depending on configuration, communication options include:
HART
PROFIBUS DP
PROFIBUS PA
FOUNDATION Fieldbus
Modbus RS485
Modbus TCP over Ethernet-APL
PROFINET
Ethernet/IP
OPC-UA
This makes the flowmeter suitable for integration into PLC, DCS, SCADA and plant automation systems.
Multivariable Measurement
Promass S 500 can measure multiple process variables from a single instrument, including:
Mass flow
Volume flow
Corrected volume flow
Density
Reference density
Temperature
Concentration
Multivariable measurement can reduce the number of separate measuring points required in a process installation.
Hygienic Materials and Connections
The measuring tube is manufactured from 1.4435 (316L) stainless steel, while process connections are available in 1.4435 (316L) and 1.4404 (316/316L).
Promass S 500 offers a broad selection of hygienic process connections, allowing the flowmeter to be adapted to different sanitary piping configurations.
Compact Hygienic Sensor Connection
The remote sensor version features a hygienic sensor connection housing with IP69 protection, supporting reliable operation in demanding food and beverage environments exposed to regular cleaning and washdown procedures.
Heartbeat Technology
Promass S 500 incorporates Endress+Hauser Heartbeat Technology for integrated device verification and diagnostics.
Heartbeat Technology helps provide greater insight into instrument condition and measurement performance, supporting process safety and maintenance planning.
