Flow indicator for bulk solids
- In conformity with ATEX, IECEx, CSA and EAC

The FTR20 flow indicator for bulk solids is used for the non-contact and wear-free detection of pneumatically or mechanically transport processes of bulk solids of all kinds (flow/no flow). The compact device can be installed on containers, conduits, shafts or on free fall shafts. It is possible to take a measurement through non-metallic container materials from the outside. By metallic containers it is recommended to use microwave-permeable windows made of glass, ceramic or PTFE.

The function of the flow indicator for bulk solids is largely independent of the process conditions, such as the temperature and pressure in containers, aggressive or abrasive media, dust, mist, smoke and sediment deposits.

In addition to a switching output, the FTR20 also has an analog 4-20 mA current output, using which the change in the mass flow can also be evaluated. Furthermore, the switching point can also be determined in the downstream system.

• Robust and reliable at different process conditions
• High profitability as it is wear and maintenance free
• Easy installation and commissioning without special tools
• Flush mounting, contactless installation possible
• Electronics housing can be rotated by 360° after installation, allowing orientation into optimum position
• Compact design
• Indication of the movement by 10 digits LED bargraph
• Selectable output signal: relay, solid-state-relay or current output 4-20 mA
• Integrated power supply and signal output, therefore no further switching amplifier required
• Many settings such as sensitivity, hysteresis, limit function, switching delay, attenuation
• Simulation mode allows the simulation of an output signal independent of the process to set, for example, a downstream PLC or data logger
• Easy mounting using R 1½, G 1½ or 1½ NPT thread, mounting bracket, installation flange, high-temperature adapter, high-pressure adapter and more
• Conforms to ATEX, IECEx, CSA and EAC
