The Endress+Hauser Proline Promass F 300 and Promass F 100 are Coriolis mass flow meters designed for demanding liquid and gas measurement. Both offer multivariable measurement capabilities, including mass flow, density, and temperature. The main selection difference is not simply measurement performance: transmitter design, installation space, local operation, and system integration also matter.
The Promass F 300 features a compact transmitter designed for convenient access, flexible system integration, and a range of communication options. Depending on configuration, it can support local operation, remote display, and multiple input/output or digital communication options.
The Promass F 100 uses an ultra-compact transmitter design. It is particularly suitable for skid builders, equipment manufacturers, and system integrators who need high-performance measurement in a limited installation space. Local display options and communication features depend on the selected configuration.
| Selection factor | Promass F 300 | Promass F 100 |
|---|---|---|
| Transmitter design | Compact, accessible transmitter | Ultra-compact transmitter |
| Installation priority | Flexible operation and integration | Space-saving equipment design |
| Local operation | Display and operating options available | Local display option available |
| System integration | Broad configurable I/O and communication options | Compact integration; verify available interfaces |
| Measurement principle | Coriolis | Coriolis |
| Typical selection focus | Process visibility and integration flexibility | Compact skids and equipment |
Exact communication protocols, outputs, approvals, and display configurations depend on the order code.
Both models use the Promass F measuring principle and are designed for demanding process conditions. Their capabilities should be assessed against the required flow range, medium temperature, process pressure, wetted materials, and measurement accuracy.
Do not assume that the F 300 is automatically more accurate than the F 100 simply because of its transmitter design. The specified sensor performance, calibration option, and exact configuration are more relevant to the accuracy comparison.
Coriolis meters can measure mass flow directly and provide additional variables such as density and temperature. This can reduce the need for separate measurement instruments in suitable applications.
Consider the Promass F 300 when convenient local operation, diagnostic access, and flexible integration are important to the project.
Consider the Promass F 100 when transmitter size is a key constraint, such as on compact process skids or OEM equipment.
For either model, confirm the fluid, minimum and maximum flow rates, operating pressure and temperature, process connections, wetted materials, electrical supply, and required communication protocol before ordering.
For projects that require a Coriolis meter, the Endress+Hauser Promass F series is worth evaluating where reliable mass flow measurement is needed under changing process conditions. Other Promass families may also be suitable depending on the application and measurement requirements.
When requesting a quotation, provide the complete model code or order configuration whenever possible. This helps confirm the measuring tube, connection, transmitter, outputs, approvals, and accessories rather than comparing product names alone.
Promass F 300 and F 100 share the same core Coriolis measurement approach, but their transmitter designs serve different installation and integration priorities. Select the model according to the actual process conditions and required functions, then verify the complete order code against the technical specification.
