Endress+Hauser Proline Promass I 100 Coriolis Flowmeter
The Endress+Hauser Proline Promass I 100 is a compact Coriolis flowmeter for accurate measurement of liquids and gases, designed for applications where low pressure loss, gentle fluid treatment and space-saving installation are important. Its distinctive feature is the ability to combine conventional Coriolis flow measurement with optional in-line viscosity measurement in a single instrument.
The Promass I 100 uses a straight, single-tube measuring system with a full-bore design. This provides a relatively unobstructed flow path, helping minimize pressure loss and making the instrument suitable for applications where energy efficiency and gentle handling of the process medium are important.
Coriolis Flow and In-Line Viscosity Measurement
The Promass I 100 provides the standard Coriolis measurement variables of mass flow, density and temperature, while also offering in-line viscosity measurement as an optional output.
This combination makes the instrument particularly useful where viscosity is an important process parameter and would otherwise require a separate measurement device. The available measured variables include:
Mass flow
Volume flow
Corrected volume flow
Density
Reference density
Temperature
Concentration
Viscosity
Accurate Liquid and Gas Measurement
Promass I 100 provides accurate measurement for both liquids and gases:
Liquid mass flow: ±0.10%
Liquid volume flow: ±0.10%
Gas mass flow: ±0.50%
Liquid density: ±0.0005 g/cm³
The Coriolis measuring principle operates independently of physical fluid properties such as viscosity or density, while the optional viscosity measurement provides additional information about the condition and characteristics of the process fluid.
Full-Bore Single-Tube Design
The Promass I 100 features a straight single-tube measuring system with a full-bore flow path.
This design provides several advantages:
Minimal pressure loss
Gentle treatment of the process medium
Easy cleaning
Compact installation
No conventional inlet and outlet straight pipe runs required
The straight measuring tube is particularly beneficial for applications where maintaining product quality and minimizing energy losses are important.
Titanium Measuring Tube
The wetted measuring tube of Promass I 100 is manufactured from Titanium Grade 9, with the process connection made from Titanium Grade 2.
The titanium construction provides a robust solution for applications requiring corrosion-resistant wetted materials.
Compact Design for Skids and Equipment
Promass I 100 is specifically positioned for system integrators, skid builders and equipment manufacturers.
Its straight single-tube sensor and ultra-compact transmitter provide full measurement functionality within a small footprint. This makes the flowmeter suitable for:
Skid-mounted systems
OEM equipment
Process packages
Compact machinery
Industrial equipment
Applications with limited installation space
Ultra-Compact Transmitter
A major advantage of the Promass I 100 is its ultra-compact transmitter housing.
The transmitter is designed to provide full functionality while occupying minimal space. It also includes an integrated web server, allowing configuration and operation through a web browser without requiring additional operating hardware or software.
The transmitter is available with a local display option and provides a high degree of environmental protection, with IP66/67 as standard and IP69 as an option.
Low Pressure Loss and Energy Efficiency
The full-bore design of the Promass I 100 enables minimal pressure loss compared with flowmeter designs that significantly obstruct the process flow.
This can help reduce the energy required to move the process medium through the piping system. It is especially useful in applications where pressure loss, pumping costs or gentle fluid treatment are important design considerations.
Wide Measuring Range
Promass I 100 is available in nominal diameters from DN8 to DN80 (3/8 to 3").
The maximum measuring range reaches 180,000 kg/h (6,600 lb/min), allowing the instrument to cover a broad range of industrial liquid and gas flow applications.
Process Temperature and Pressure
The Promass I 100 is designed for demanding process conditions:
Medium temperature: -50 to +150 °C (-58 to +302 °F)
Maximum process pressure: PN 100, Class 600, 63K
Nominal diameter: DN8 to DN80
Flexible Communication
Promass I 100 supports multiple communication technologies for integration into industrial automation systems, including:
HART
Modbus RS485
EtherNet/IP
PROFIBUS DP
PROFINET
The standard outputs include 4–20 mA HART and a passive pulse/frequency/switch output.
This makes Promass I 100 suitable for integration with PLC, DCS, SCADA and other process automation systems.
Multivariable Process Measurement
By combining Coriolis measurement with optional viscosity measurement, the Promass I 100 can provide multiple process variables from one measurement point.
This can reduce the number of individual instruments required and provide additional information for process monitoring, quality control and equipment optimization.
Heartbeat Technology
The Promass I 100 incorporates Endress+Hauser Heartbeat Technology for integrated verification and diagnostics.
Heartbeat Technology supports measurement verification and provides traceability for measurement performance without requiring the flowmeter to be removed from the process. The product is also calibrated at accredited facilities according to ISO/IEC 17025.
