Endress+Hauser Microwa
Endress+Hauser Microwave flow indicator
For monitoring pneumatic and mechanical transport processes for bulk solids
The Solimotion FTR20 flow indicator for bulk solids is a non-contact device based on microwave technology. It is ideally suited for cost-effective monitoring of a mass flow (present or not present). The compact device can be used wherever the cost-effective monitoring of bulk solids movement is required. Individual adjustments to the application can be carried out by means of configurable functions (incl. automatic calibration).
Benefits
- Sensor, transmitter and power unit mounted in one housing, which means less effort for installation and mounting
- High safety level compliant with international explosion protection certificates
- Flush-mounted installation, non-contact installation possible for ideal integration into the process
- Electronics housing can be rotated by 360° allowing adjustment into optimum position after installation
- High cost-effectiveness thanks to its mechanical robustness: No wear, process-wetted ceramic sensor diaphragm (optional), long service life, maintenance-free
- Signaling of mass flow (present or not present)
Field of application
Building materials industry: Cement, plaster, wood chips etc.
Chemicals: Fertilizers, plastic powder and granules, silica etc.
Food industry: Coffee, tea, tobacco, cereals, animal feeds etc.
Energy production: Coal, carbon dust, fly-ash, coke etc.
- Process connections: Threads or a suitable mounting bracket
