Endress+Hauser Proline Promass I 300 Coriolis Flowmeter
The Endress+Hauser Proline Promass I 300 is a high-performance Coriolis flowmeter for accurate liquid and gas measurement, designed for demanding process applications where reliable flow measurement, low pressure loss and additional process information are important.
A key feature of Promass I 300 is its optional in-line viscosity measurement. By combining Coriolis flow measurement with viscosity measurement in one instrument, the device can provide more comprehensive process information without requiring a separate viscosity analyzer.
The Promass I sensor uses a straight single-tube measuring system with a full-bore flow path, helping minimize pressure loss and providing gentle treatment of the process medium.
Coriolis Flow and In-Line Viscosity Measurement
Promass I 300 can measure multiple process variables from a single measuring point, including:
Mass flow
Volume flow
Corrected volume flow
Density
Reference density
Temperature
Concentration
Viscosity
The optional in-line viscosity measurement makes Promass I 300 particularly useful for applications where viscosity is an important indicator of product quality, process condition or fluid composition.
Accurate Liquid and Gas Flow Measurement
The Promass I 300 provides accurate measurement for both liquids and gases.
The Coriolis measuring principle directly measures mass flow and also provides density and temperature information. This enables reliable flow measurement even when process conditions or fluid properties vary.
The straight-tube design also helps minimize pressure loss compared with flowmeter designs that significantly obstruct the process flow.
Straight Single-Tube Full-Bore Design
One of the main design advantages of the Promass I sensor is its straight single-tube construction.
The full-bore measuring tube provides a relatively unobstructed flow path, offering:
Low pressure loss
Gentle product treatment
Easy cleaning
Reduced risk of product retention
Flexible installation
The Coriolis principle also means that conventional inlet and outlet straight pipe runs are generally not required, helping simplify piping design.
Robust Remote Transmitter
Unlike the compact Promass I 100, the Promass I 300 uses a remote transmitter configuration, allowing the transmitter to be installed separately from the sensor.
This is useful when:
The measuring point is difficult to access
The process line is installed in a restricted area
The display needs to be positioned away from the process
Ambient conditions near the sensor are demanding
Easier operation and maintenance access is required
The remote configuration provides greater flexibility for process plant installation and system layout.
Wide Measuring Range
Promass I 300 is available in nominal diameters from DN8 to DN80, covering a broad range of industrial flow applications.
The instrument can be configured for different process connections and operating conditions to meet specific application requirements.
High Process Performance
Promass I 300 is designed for demanding process environments and supports:
High measurement accuracy
Reliable density measurement
Temperature measurement
Optional viscosity measurement
Concentration measurement
Low pressure loss
Continuous process monitoring
This makes it suitable for applications where flow measurement alone is not sufficient and additional fluid information is required.
Process Temperature and Pressure
Depending on the selected configuration, Promass I 300 can be used across a wide range of process conditions.
The instrument is designed for industrial applications requiring reliable operation under changing process temperature and pressure conditions.
The sensor construction and available process connections can be selected according to the required process pressure, temperature and fluid compatibility.
Flexible Communication and Integration
The Promass I 300 transmitter provides flexible integration with modern process automation systems.
Depending on configuration, communication options include:
HART
PROFIBUS DP
PROFINET
Modbus RS485
EtherNet/IP
Other digital communication technologies
This allows Promass I 300 to be integrated into PLC, DCS, SCADA and plant asset management systems.
Easy Commissioning and Operation
The Promass I 300 transmitter is designed to simplify commissioning and everyday operation.
The transmitter supports a local display and convenient device configuration, while digital communication and web-based access options can provide additional flexibility for device setup and diagnostics.
This makes the instrument suitable for both standalone measurement points and larger automated process systems.
Heartbeat Technology
Promass I 300 incorporates Endress+Hauser Heartbeat Technology for integrated device verification, diagnostics and monitoring.
Heartbeat Technology helps users verify measurement performance without removing the flowmeter from the process, supporting:
Preventive maintenance
Measurement verification
Process reliability
Reduced unplanned downtime
Improved measurement traceability
