Endress+Hauser Proline Cubemass C 500 Coriolis Flowmeter

The Endress+Hauser Proline Cubemass C 500 is a compact Coriolis flowmeter designed for accurate measurement of the smallest liquid and gas flow rates. It combines a space-saving single-tube sensor with a remote transmitter, providing greater installation flexibility for demanding process environments.

Cubemass C 500 is particularly suitable for skids, test rigs, industrial robotics and compact process equipment, where accurate low-flow measurement must be combined with limited installation space. The Coriolis measuring principle provides direct mass flow measurement and also enables measurement of density, temperature and volume flow.

Precise Small-Flow Measurement

Cubemass C 500 is optimized for measuring very small quantities of liquids and gases. The sensor is available in nominal diameters from DN1 to DN6 (1/24 to 1/4"), with a measuring range of 0 to 1,000 kg/h (0 to 37 lb/min).

This makes the flowmeter suitable for applications requiring accurate measurement at low flow rates, including:

• 
  Small-flow liquid measurement
  
• 
  Small-flow gas measurement
  
• 
  Precision dosing
  
• 
  Chemical process measurement
  
• 
  Skid-mounted systems
  
• 
  Test rigs
  
• 
  Industrial robotics
  
• 
  Pilot plants
  
• 
  Compact process equipment
  

High Measurement Accuracy

The Cubemass C 500 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 instrument supports multivariable measurement of mass flow, volume flow, density and temperature, reducing the need for separate measurement points in compact process systems.

Compact Single-Tube Sensor

The sensor uses a compact single-tube design that minimizes installation space while maintaining accurate Coriolis measurement.

The lightweight sensor is especially suitable for skid systems and equipment packages where weight and available installation space are important considerations. The wetted measuring tube is made from 904L stainless steel, with process connections available in 904L and 316/316L stainless steel depending on configuration.

High-Pressure Process Measurement

Despite its compact dimensions, Cubemass C 500 is designed for demanding process conditions.

The maximum process pressure reaches 400 bar (5800 psi), while the medium temperature range extends from -50 to +205 °C (-58 to +401 °F).

This combination of very low-flow measurement, high pressure and wide temperature capability makes Cubemass C 500 suitable for specialized industrial applications.

Remote Transmitter for Installation Flexibility

The defining feature of the Cubemass C 500 is its remote transmitter configuration.

The sensor and transmitter are connected using a standard cable, allowing the transmitter to be installed separately from the measuring point. This provides greater flexibility when the sensor is installed in a restricted location or a difficult-to-access process area.

The remote transmitter supports up to four I/Os, providing flexible access to process and diagnostic information.

Flexible Digital Connectivity

Cubemass C 500 provides extensive connectivity options for integration into modern industrial automation systems.

The transmitter offers freely configurable I/O functions and fieldbus communication, helping integrate the flowmeter with PLC, DCS, SCADA and other process control systems. It also features a backlit display with touch control and WLAN access for convenient configuration and operation.

Multivariable Measurement

A single Cubemass C 500 measuring point can provide multiple process parameters, including:

• 
  Mass flow
  
• 
  Volume flow
  
• 
  Corrected volume flow
  
• 
  Density
  
• 
  Reference density
  
• 
  Temperature
  
• 
  Concentration
  

This multivariable capability can simplify instrumentation architecture and provide additional process information without requiring multiple independent instruments.

Designed for Skids and Test Rigs

The compact sensor makes Cubemass C 500 particularly suitable for skid-mounted systems, test rigs and industrial robotics.

For OEMs and system integrators, the lightweight sensor and remote transmitter allow the measuring point and operating interface to be positioned according to the equipment layout, helping optimize installation and maintenance access.

Heartbeat Technology

Cubemass C 500 incorporates Endress+Hauser Heartbeat Technology, providing integrated verification and diagnostic functions.

Heartbeat Technology supports measurement reliability and compliant verification, helping users verify instrument performance without removing the flowmeter from the process.
