Function and system design
Operating principle The FTR20 flow indicator for bulk solids works using microwave technology. A signal is transmitted, and this
signal is reflected by the moving bulk solids. The FTR20 measures the strength of the reflected, frequency-
shifted (Doppler effect) energy, this is analyzed and put out via the display or the signal output.
The range of the FTR20 is influenced by varying materials, with the attenuation depending on the damping
characteristics of the bulk solids.
Example of
volumetric dosing
	The FTR20 monitors the outflow of a screw conveyor. If the flow of material slows down (for example
due to clogging of the pipe leading downwards or if there is no material being conveyed due to a failure
in the screw conveyor), the device generates a message to this effect. This can then be processed further
in the system.

Example of a conveyor belt
The FTR20 monitors the continuous mass flow at a transition point, a break in the flow is detected and put
out at the signal output.

Input
Measured variable Doppler frequency
Measuring range
(detection range)
With an unobstructed radiation path to the surface of the bulk solids, the maximum range is 20 m.
This is reduced if container walls, sight glasses or similar need to be penetrated.
Operating frequency 24.15 GHz ± 80 MHz
Transmission power The power produced by the FTR20 is maximum 100 mW e.i.r.p. (equivalent isotrope radiation
performance).
•	Power density directly in front of the device:	 approx. 1 mW/cm2
•	Power density at a distance of 1 m:			 approx. 0.3 µW/cm2
Note:
The power density is clearly under the recommended limit values of the ICNIRP guidelines Guidelines for
Limiting Exposure to Time-Varying Electric, Magnetic, and Electromagnetic Fields (up to 300 GHz) and
thus is completely harmless for humans.
Switching frequency max. 2 Hz

Operating conditions
Installation instructions The FTR20 bulk solids motion detector comes with a standard thread (R 1½ as per EN 10226 or 1½ NPT
as per ANSI/ASME B1.20.1) as a process connection. This enables easy installation in existing container
couplings or nozzles. For optimal orientation after installation in the process, the electronics housing can be
rotated as desired (by 360°).
2.5 hex
Following installation, the housing must be secured using the Allen head screw (2.5 AF).
Orientation

	 Any orientation is possible for the FTR20 bulk solids motion detector. However, a small angle α may increase
	 the signal quality.

*3	The distance A is based on the nominal width of the sight glass fitting (or the diameter of the sight glass)
and the temperature at the fitting. To prevent possible signal attenuation, we recommend keeping the
distance as short as possible (e.g. max. 40 mm at DN50).
*4	Distance to temperature reduction between process temperature and max. 70°C at the flow indicator for

*5	Various installation adapters (e.g. for angle installation) are available as special equipment packages.
*6	We recommend using purge air to prevent fouling (material accumulation) in the nozzle that is open to
the process. Alternatively, you can also close the nozzle using a plastic plug (see next page).

Note:
•	This type of mounting is recommended if conditions at the process or in the area surrounding the
process are unfavorable (such as high temperatures or heavy contamination) or if the building's situation
does not permit direct installation.
•	The pipe can be made from any metallic material, and the length is not important due to the wave guide
effect.
•	Edges inside the pipe (for example at transitions) can cause signal attenuation and thus should be avoided
wherever possible.

Settings
By using frequencies in the 24 GHz range, the material flow of products with low attenuation can be de-
tected, even if the product quantities are low. The calibration options for the FTR20 flow indicator for bulk
solids offer the necessary flexibility to ensure that the device can be easily adapted to the application:
•	Adjustable sensitivity
•	Switchable signal function:
	 - Switch point exceeded = max. safety (e.g. overflow protection) or
	 - Switch point not reached = min. safety (e.g. dry running protection)
•	Adjustable switching hysteresis (not for current output)
•	Switching delay (not at current output):
	 - 100 ms to 20 s
	 - Response and drop-out delay, can be selected separately
•	LED field strength indicator as an adjustment and positioning aid

The FTR20 is configured using the function selection m and the two operating keys q and r. For this
purpose, calibration to a sensitivity necessary for clear and unambiguous material flow identification of the
products is carried out. If the movement of the bulk solids is sufficient, the FTR20 responds with an output
signal to this effect.
The parameter configuration is stored internally and is retained even after the supply voltage is disconnected.
No other operator intervention is necessary during operation. The adaptation to the application is required
during initial installation only. However, subsequent changes can be made and stored at any time.

Display The signal strength of the product as well as the configured values (in the function selection) are displayed
locally using a bar graph display o. In addition, a green LED n indicates that the device is ready to operate
(supply voltage is present) and a yellow LED p displays the status of the switch output (LED off: relay in rest
position, solid-state relay high-impedance).
Note:
•	Toggling the encoding switch for the function selection ( 0) puts the FTR20 into parameter configura-
	 tion mode. The bulk solids motion detector continues to work in the background, changed settings are
	 taken into account directly.
•	Remember to reset the function selection to 0 = operation when you have finished configuring settings.
•	For current output, the yellow LED p has no function and remains off.
Parameter configuration Parameter configuration is performed as follows:
1.		 Select any function (the available functions can be found in the section Programming functions)
		 È	 Encoding switch m = 1 to F
		 È	 The display shows the selected function for two seconds.
			 Example function 3:
2.		 Setting the selected function
		 Example: Function 3 (manual calibration with movement of bulk solids)
		 È	 Using the r Æ and q Å keys, the sensitivity can be increased or reduced in 10% increments.
				 	 or	
			 È Å	 	 È Æ	
			 È Å	 	 È Æ	
			 ...		 ...
3.		 The configured value is stored as soon as the function is switched. The value can be displayed again at
		 any time by selecting the corresponding programming function and changed if necessary.
4.		 Once parameter configuration is complete (i.e. once the motion detector has been adapted to the bulk
		 solids in question), the encoding switch must be returned to the 0 position. The FTR20 is now ready
		 for operation.
Note:
When a calibration is carried out, it can be read out and, for example in the case of a device change, trans-
ferred directly to the new FTR20. If the new device is installed in the same position, this means that the
device is correctly calibrated.

Solimotion FTR20
Endress+Hauser 25
High-temperature
application
For applications with process temperatures up to +450°C, the temperature reduction to max. +70°C takes
place on the FTR20 using an appropriate high-temperature adapter (with extension where necessary).
The length of the adapter is based on the insulation thickness to be penetrated (if present) and the
ambient conditions at the measuring point.
Tmax = +70°CTP,max = +450°C
Pmax = 80 to 510 kPa abs.
(0.8 to 5.1 bar abs.)

Extension
X
Note:
•	To maintain the maximum temperature of +70°C at the FTR20, we recommend a minimum difference of
	 (X) 200 mm between the process or the insulation and the device.
•	The individual extensions can also be combined in any way desired.
•	Each high-temperature adapter results in a reduction of the range.

  • 3. Solimotion FTR20 Endress+Hauser 3 Function and system design Operating principle The FTR20 flow indicator for bulk solids works using microwave technology. A signal is transmitted, and this signal is reflected by the moving bulk solids. The FTR20 measures the strength of the reflected, frequency- shifted (Doppler effect) energy, this is analyzed and put out via the display or the signal output. The range of the FTR20 is influenced by varying materials, with the attenuation depending on the damping characteristics of the bulk solids. Example of volumetric dosing The FTR20 monitors the outflow of a screw conveyor. If the flow of material slows down (for example due to clogging of the pipe leading downwards or if there is no material being conveyed due to a failure in the screw conveyor), the device generates a message to this effect. This can then be processed further in the system.
  • 4. 4 Solimotion FTR20 Endress+Hauser Example of a conveyor belt The FTR20 monitors the continuous mass flow at a transition point, a break in the flow is detected and put out at the signal output.
  • 5. Solimotion FTR20 Endress+Hauser 5 Input Measured variable Doppler frequency Measuring range (detection range) With an unobstructed radiation path to the surface of the bulk solids, the maximum range is 20 m. This is reduced if container walls, sight glasses or similar need to be penetrated. Operating frequency 24.15 GHz ± 80 MHz Transmission power The power produced by the FTR20 is maximum 100 mW e.i.r.p. (equivalent isotrope radiation performance). • Power density directly in front of the device: approx. 1 mW/cm2 • Power density at a distance of 1 m: approx. 0.3 µW/cm2 Note: The power density is clearly under the recommended limit values of the ICNIRP guidelines Guidelines for Limiting Exposure to Time-Varying Electric, Magnetic, and Electromagnetic Fields (up to 300 GHz) and thus is completely harmless for humans. Switching frequency max. 2 Hz
  • 6. 6 Solimotion FTR20 Endress+Hauser Output Relay • Potential-free change-over contact • Switching capacity: - AC: 250 V / 6 A - DC: 125 V / 0.4 A or 30 V / 5 A • Contact material: AgCdO (gold-flashed) • Switching frequency: max. 2 Hz 3 4 5 Note: The contact material is also suitable for switching small signal circuits. However, this is possible only if no inductive loads or higher currents have been switched previously. Solid-state relay • Switching contact of a semiconductor relay • Switching capacity: - AC: 30 V / 0.4 A - DC: 40 V / 0.4 A • Switching frequency: max. 2 Hz 3 4 Note: Unlike the switching contact of the relay output, this can be used to evaluate higher switching frequencies (e.g. for piece goods counting).

  • 8. 8 Solimotion FTR20 Endress+Hauser Operating conditions Installation instructions The FTR20 bulk solids motion detector comes with a standard thread (R 1½ as per EN 10226 or 1½ NPT as per ANSI/ASME B1.20.1) as a process connection. This enables easy installation in existing container couplings or nozzles. For optimal orientation after installation in the process, the electronics housing can be rotated as desired (by 360°). 2.5 hex Following installation, the housing must be secured using the Allen head screw (2.5 AF). Orientation αα Any orientation is possible for the FTR20 bulk solids motion detector. However, a small angle α may increase the signal quality.

  • 13. Solimotion FTR20 Endress+Hauser 13 Installation with pipe as wave guide L Note: • This type of mounting is recommended if conditions at the process or in the area surrounding the process are unfavorable (such as high temperatures or heavy contamination) or if the building's situation does not permit direct installation. • The pipe can be made from any metallic material, and the length is not important due to the wave guide effect. • Edges inside the pipe (for example at transitions) can cause signal attenuation and thus should be avoided wherever possible.

  • 15. Solimotion FTR20 Endress+Hauser 15 Settings By using frequencies in the 24 GHz range, the material flow of products with low attenuation can be de- tected, even if the product quantities are low. The calibration options for the FTR20 flow indicator for bulk solids offer the necessary flexibility to ensure that the device can be easily adapted to the application: • Adjustable sensitivity • Switchable signal function: - Switch point exceeded = max. safety (e.g. overflow protection) or - Switch point not reached = min. safety (e.g. dry running protection) • Adjustable switching hysteresis (not for current output) • Switching delay (not at current output): - 100 ms to 20 s - Response and drop-out delay, can be selected separately • LED field strength indicator as an adjustment and positioning aid Operation 0F EDCBA 987 65432 1 m r q pon The FTR20 is configured using the function selection m and the two operating keys q and r. For this purpose, calibration to a sensitivity necessary for clear and unambiguous material flow identification of the products is carried out. If the movement of the bulk solids is sufficient, the FTR20 responds with an output signal to this effect. The parameter configuration is stored internally and is retained even after the supply voltage is disconnected. No other operator intervention is necessary during operation. The adaptation to the application is required during initial installation only. However, subsequent changes can be made and stored at any time.
  • 16. 16 Solimotion FTR20 Endress+Hauser Display The signal strength of the product as well as the configured values (in the function selection) are displayed locally using a bar graph display o. In addition, a green LED n indicates that the device is ready to operate (supply voltage is present) and a yellow LED p displays the status of the switch output (LED off: relay in rest position, solid-state relay high-impedance). Note: • Toggling the encoding switch for the function selection ( 0) puts the FTR20 into parameter configura- tion mode. The bulk solids motion detector continues to work in the background, changed settings are taken into account directly. • Remember to reset the function selection to 0 = operation when you have finished configuring settings. • For current output, the yellow LED p has no function and remains off. Parameter configuration Parameter configuration is performed as follows: 1. Select any function (the available functions can be found in the section Programming functions) È Encoding switch m = 1 to F È The display shows the selected function for two seconds. Example function 3: 2. Setting the selected function Example: Function 3 (manual calibration with movement of bulk solids) È Using the r Æ and q Å keys, the sensitivity can be increased or reduced in 10% increments. or È Å È Æ È Å È Æ ... ... 3. The configured value is stored as soon as the function is switched. The value can be displayed again at any time by selecting the corresponding programming function and changed if necessary. 4. Once parameter configuration is complete (i.e. once the motion detector has been adapted to the bulk solids in question), the encoding switch must be returned to the 0 position. The FTR20 is now ready for operation. Note: When a calibration is carried out, it can be read out and, for example in the case of a device change, trans- ferred directly to the new FTR20. If the new device is installed in the same position, this means that the device is correctly calibrated.

  • 25. Solimotion FTR20 Endress+Hauser 25 High-temperature application For applications with process temperatures up to +450°C, the temperature reduction to max. +70°C takes place on the FTR20 using an appropriate high-temperature adapter (with extension where necessary). The length of the adapter is based on the insulation thickness to be penetrated (if present) and the ambient conditions at the measuring point. Tmax = +70°CTP,max = +450°C Pmax = 80 to 510 kPa abs. (0.8 to 5.1 bar abs.) Wall Insulation HT adapter Extension X Note: • To maintain the maximum temperature of +70°C at the FTR20, we recommend a minimum difference of (X) 200 mm between the process or the insulation and the device. • The individual extensions can also be combined in any way desired. • Each high-temperature adapter results in a reduction of the range.
