Field of application
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).
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
Temperature: -40 to +450°C (-40 to +842°F), with adapter for temperature reduction
Pressure: 0.5 to 6.8bar abs standard (7.2 to 98.6psi abs)
International explosion protection certificates
