Endress+Hauser Proline Cubemass C 300 Coriolis Flowmeter
The Endress+Hauser Proline Cubemass C 300 is a compact Coriolis flowmeter designed for accurate measurement of the smallest quantities of liquids and gases. It combines a space-saving single-tube sensor with a compact, easily accessible transmitter, making it well suited for skids, test rigs, industrial robotics and other space-constrained process systems.
Cubemass C 300 uses the Coriolis measuring principle to directly measure mass flow while also providing density, temperature and volume flow information. The measurement principle operates independently of physical fluid properties such as viscosity and density, helping provide stable measurement performance under changing process conditions.
Precise Measurement of Very Small Flow Rates
The Cubemass C series is specifically designed for smallest flow quantities. Cubemass C 300 is available in nominal diameters from DN1 to DN6 (1/24 to 1/4"), with a measuring range of up to 1,000 kg/h (37 lb/min).
This makes it suitable for applications where accurate low-flow measurement is required without using a large flowmeter.
Typical applications include:
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-Accuracy Coriolis Measurement
The Promass/Cubemass Coriolis technology provides accurate measurement of both liquids and gases. For Cubemass C 300, the maximum measurement errors are:
Liquid mass flow: ±0.10%
Liquid volume flow: ±0.10%
Gas mass flow: ±0.50%
Liquid density: ±0.0005 g/cm³
The instrument can measure multiple process variables from a single measuring point, including mass flow, volume flow, corrected volume flow, density, reference density, temperature and concentration.
Compact Single-Tube Sensor
The Cubemass C 300 features a space-saving single-tube sensor with a lightweight construction. This design helps simplify installation in compact equipment and skid systems where available space is limited.
The wetted measuring tube is manufactured from 1.4539 (904L) stainless steel, while the process connections are available in 1.4539 (904L) and 1.4404 (316/316L) depending on configuration.
The compact sensor design also supports applications where measurement accuracy must be maintained under high pressure and alternating flow conditions.
High-Pressure Process Measurement
Despite its compact size, Cubemass C 300 supports demanding process conditions.
The maximum process pressure reaches 400 bar (5800 psi), while the medium temperature range is -50 to +205 °C (-58 to +401 °F).
This combination of small-flow measurement, high pressure and wide temperature capability makes Cubemass C 300 suitable for specialized industrial process applications.
Compact and Easily Accessible Transmitter
One of the defining features of Cubemass C 300 is its compact, easily accessible transmitter.
The transmitter uses a dual-compartment housing and provides access to process and diagnostic information through flexible I/O and fieldbus configurations. It supports up to three I/Os, while the backlit display provides touch control and WLAN access. A remote display is also available.
The transmitter can be accessed from one side, which can simplify operation and maintenance in installations with limited access space.
Flexible Digital Connectivity
Cubemass C 300 offers extensive communication options for integration into modern industrial automation systems.
Supported communication technologies include:
HART
PROFIBUS DP
PROFIBUS PA
FOUNDATION Fieldbus
Modbus RS485
MODBUS TCP over Ethernet-APL
PROFINET
PROFINET over Ethernet-APL
EtherNet/IP
OPC-UA
This makes the flowmeter suitable for integration with PLC, DCS, SCADA and other industrial control systems.
Multivariable Measurement
Cubemass C 300 can provide several process variables from a single measuring point:
Mass flow
Volume flow
Corrected volume flow
Density
Reference density
Temperature
Concentration
This multivariable capability can help reduce the number of individual measurement instruments required in compact process systems.
Designed for Skids, Test Rigs and Robotics
The compact dimensions and lightweight sensor make Cubemass C 300 particularly suitable for skid-mounted equipment, test rigs and industrial robotics.
For system integrators and equipment manufacturers, its compact footprint allows accurate Coriolis measurement to be incorporated into equipment packages without requiring excessive installation space.
Heartbeat Technology
The Cubemass C 300 incorporates Endress+Hauser Heartbeat Technology for integrated measurement verification and diagnostics.
Heartbeat Technology helps users verify measurement performance and support compliant verification without removing the flowmeter from the process. This can contribute to improved measurement reliability, preventive maintenance and process availability.
