Endress+Hauser Proline Promass S 300 Coriolis Flowmeter
The Endress+Hauser Proline Promass S 300 is a hygienic Coriolis flowmeter designed for the Food & Beverage industry, where reliable measurement, optimal cleanability and hygienic process design are essential. The instrument combines accurate flow and density measurement with a self-drainable single-tube measuring system and a compact, easily accessible transmitter.
Promass S 300 is particularly suitable for hygienic liquid measurement applications requiring frequent CIP/SIP cleaning, sanitary process connections and reliable operation in demanding food and beverage production environments.
Hygienic Coriolis Flow Measurement
The Promass S 300 uses the Coriolis measuring principle, providing accurate measurement while operating independently of physical fluid properties such as viscosity and density.
Key measurement performance includes:
Liquid mass flow accuracy: ±0.10%
Liquid volume flow accuracy: ±0.10%
Liquid density accuracy: ±0.0005 g/cm³
Maximum measuring range: 70,000 kg/h
Medium temperature: -50 to +150 °C
Maximum process pressure: PN 40 / Class 150 / 20K
Self-Drainable Single-Tube Design
A major advantage of Promass S 300 is its easy-to-clean, fully self-drainable single-tube system.
The hygienic measuring tube design helps:
Improve process hygiene
Minimize product residue
Simplify cleaning
Support complete drainage
Reduce the risk of product contamination
Simplify hygienic installation
The single-tube construction also provides a compact measurement solution for applications where installation space is limited.
Designed for Food & Beverage Applications
Promass S 300 is specifically dedicated to Food & Beverage applications requiring optimal cleanability under hygienic conditions.
Typical applications include:
Food processing
Beverage production
Dairy processing
Liquid food ingredients
Hygienic liquid transfer
Sanitary process measurement
CIP/SIP process systems
Food and beverage production skids
The instrument supports hygienic process requirements with a wide range of sanitary process connections and 3-A and EHEDG conformity.
Fast CIP/SIP Recovery
Promass S 300 is designed for rapid recovery from CIP (Clean-in-Place) and SIP (Sterilization-in-Place) procedures.
This is particularly important in food and beverage plants where cleaning and sterilization cycles are performed regularly and production downtime needs to be minimized.
Hygienic Process Connections
The flowmeter offers a large range of hygienic process connections, allowing it to be adapted to different sanitary piping systems.
The combination of hygienic connections, 316L wetted materials, self-drainability and cleanable tube design makes Promass S 300 suitable for demanding sanitary process installations.
Compact Transmitter with Flexible Operation
Promass S 300 features a compact hygienic dual-compartment transmitter housing with up to 3 configurable I/Os.
The transmitter provides:
Backlit display
Touch control
WLAN access
Remote display option
Flexible I/O configuration
Fieldbus connectivity
Process information access
Diagnostic information access
The transmitter can be accessed from one side, helping simplify operation and maintenance in compact process installations.
Flexible System Integration
Promass S 300 provides flexible connectivity for integration into modern process automation systems.
Its freely combinable I/Os and fieldbus options support connection with:
PLC systems
DCS systems
SCADA systems
Process control systems
Plant asset management systems
The transmitter also supports modern Ethernet-based communication, including Ethernet-APL, depending on configuration.
Multivariable Measurement
Promass S 300 can provide multiple process variables from a single measurement point:
Mass flow
Volume flow
Corrected volume flow
Density
Reference density
Temperature
Concentration
This multivariable functionality can reduce the number of separate instruments required for hygienic process monitoring.
Compact Installation
The Promass S 300 is designed for space-saving installation.
Because the Coriolis measuring principle does not require conventional inlet and outlet straight pipe runs, the instrument can be installed in compact hygienic process systems where piping space is limited.
316L Stainless Steel Wetted Materials
The measuring tube is manufactured from:
1.4435 (316L) stainless steel
Available process connection materials include:
1.4435 (316L) and 1.4404 (316/316L).
These materials are well suited to hygienic process environments and frequent cleaning procedures.
IP69 Hygienic Transmitter
The compact transmitter housing provides IP69 protection, supporting reliable operation in demanding hygienic production environments.
This is particularly relevant for installations exposed to regular washdown and cleaning procedures.
Heartbeat Technology
Promass S 300 incorporates Endress+Hauser Heartbeat Technology for integrated verification and diagnostics.
Heartbeat Technology helps provide continuous insight into device condition and measurement performance, supporting process safety and predictive maintenance without unnecessary removal of the instrument from the process.
Typical Applications
The Endress+Hauser Proline Promass S 300 is suitable for:
Food & Beverage processing
Hygienic liquid flow measurement
Dairy processing
Beverage production
Food ingredient measurement
Hygienic liquid transfer
CIP/SIP applications
Sanitary process systems
Compact hygienic process skids
