Endress+Hauser Proline Promass I 500 Coriolis Flowmeter
The Endress+Hauser Proline Promass I 500 is a high-performance Coriolis flowmeter for liquid and gas measurement, designed for demanding industrial applications where accurate flow measurement, low pressure loss and additional fluid-property information are required.
The Promass I 500 combines mass flow, density and temperature measurement with in-line viscosity measurement, allowing several important process parameters to be obtained from a single measuring point. Its remote transmitter configuration provides additional installation flexibility and supports up to 4 freely configurable I/Os.
In-Line Viscosity and Flow Measurement
One of the key advantages of Promass I 500 is its ability to provide in-line viscosity measurement in addition to conventional Coriolis flow measurement.
Depending on configuration, measured variables include:
Mass flow
Volume flow
Corrected volume flow
Density
Reference density
Temperature
Concentration
Viscosity
This makes the instrument particularly useful for applications where viscosity is an important process or product-quality parameter.
Straight Single-Tube Full-Bore Design
The Promass I sensor uses a straight, single-tube measuring system with a full-bore design.
The unobstructed flow path helps provide minimal pressure loss, while the straight tube design supports gentle treatment of the process medium and easy cleaning.
Additional advantages include:
Low pressure loss
Energy-saving operation
Gentle fluid treatment
Easy-to-clean measuring tube
No conventional inlet and outlet straight pipe runs required
Space-saving installation
Accurate Coriolis Measurement
Promass I 500 provides reliable measurement performance for both liquids and gases.
Key accuracy specifications include:
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, providing stable mass flow measurement across changing process conditions.
Remote Transmitter for Flexible Installation
A major feature of the Promass I 500 is its remote transmitter configuration.
The sensor and transmitter are connected by a standard cable, allowing the transmitter to be installed at a more convenient location. This is particularly useful in:
Demanding process environments
Restricted installation areas
Skid-mounted systems
Large process plants
Applications requiring easy access to the display
Installations where the sensor and operating location need to be separated
The transmitter supports up to 4 I/Os, providing considerable flexibility for process signals and system integration.
Wide Measuring Range
Promass I 500 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 flow applications.
Titanium Measuring Tube
The wetted measuring tube is manufactured from Titanium Grade 9, with the process connection manufactured from Titanium Grade 2.
The titanium construction provides a robust solution for applications requiring suitable corrosion resistance and reliable performance in demanding process environments.
Process Temperature and Pressure
Promass I 500 is designed for demanding industrial process conditions.
Key specifications include:
Medium temperature: -50 to +150 °C (-58 to +302 °F)
Maximum process pressure: PN 100 / Class 600 / 63K
Nominal diameter: DN8 to DN80
Flexible I/O and Digital Communication
The Promass I 500 transmitter provides extensive connectivity for integration into modern automation systems.
Available communication technologies include:
HART
PROFIBUS DP
PROFIBUS PA
FOUNDATION Fieldbus
Modbus RS485
PROFINET
PROFINET over Ethernet-APL
Ethernet/IP
OPC-UA
MODBUS TCP over Ethernet-APL
The transmitter also supports multiple output configurations, including 4–20 mA HART, WirelessHART, pulse/frequency/switch, double pulse and relay outputs, depending on configuration.
Display and WLAN Access
The transmitter features a 4-line backlit display with touch control, allowing operation from outside the housing.
Configuration can be performed through the local display and appropriate operating tools, while WLAN access provides additional flexibility during commissioning and maintenance.
Heartbeat Technology
Promass I 500 incorporates Endress+Hauser Heartbeat Technology for integrated verification and diagnostics.
Heartbeat Technology supports reliable measurement verification and helps users maintain measurement performance without unnecessarily removing the instrument from the process. This can support preventive maintenance, process reliability and measurement traceability.
