１．Outline
This Flow Switch is used to detect whether the solid material is flowing or not by utilizing
the high-level penetration ability of microwave and the Doppler effect.
When the microwave from the Flow Switch is reflected off the flowing solid material,
the frequency of the transmitted wave and that of the reflected wave differ according to
the Doppler effect.
If the solid material is not flowing, there is no frequency difference.
To detect whether the solid material is flowing or not, the Flow Switch judges whether there is
a frequency difference or not.
Also the microwave is not affected by any foreign matter adhering to the transmitter face of
the Flow Switch, vapor, floating dust due to the strong penetration ability.
Therefore the Flow Switch can detect the flow through the insulated pipe.

５．Example of installation
Figure 4 and 5 show the details of a typical installation.
Mount the flow switch with G1 screws.
The mounting part and the main body can be separated.
Use a sealant such as liquid gasket to fill the gap between the screw and the packing.
Use the accessory lock nut to install the flow switch on the pipe.

Installation that considers adhesion and piling up
Please install it referring to Figure 6.
Please install the cover board of teflon with a low
permittivity or a material ceramic etc. when this installation
is difficult and give to me as an installation that penetrates
the micro wave.
Important：The cover board of physical
properties of electroconductive
cannot be used.
Especially, when the measurement
thing that contains moisture
adheres, it becomes a false detection.
６．Wiring
・Use cables of Max. 1.5mm2in diameter that are suitable for the operational environment when wiring.
（Size of recommended cable：1.25sq）
Important：The diameter of the cable for the lead out connector of the terminal box
should be between 7 mm to 13 mm.
Caution ：Please execute it in the state of power supply OFF when you connect wires.
There is a possibility that the electric shock, the leak, and the ignition,
etc. happen.
Important：The state of the point of contact in Figure 7 is in the state of "Power ON ,
NoFlow".
Power supply OFF or undetection : It becomes excitation between COM-NC.

７．Adjustment
Important：・When the flow intermittently becomes interrupted.
Please adjust 'ON DELAY' and the 'OFF DELAY' volume to the optimum value.
(ON/OFF DELAY setting range: 0.1-10s)
『ON DELAY』：
The Flow Switch doesn’t output for the set time even when the material
is flowing and the detection is being made.
『OFF DELAY』：The Flow Switch keeps the output detected before the material stops
flowing for the set time.
7-1. Please turn on the power supply after confirming wiring after installing Flow Switch.
The POWER lamp (green) lights when the power supply is turned on.
7-2. Turn the ON-DELAY and OFF-DELAY volumes counterclockwise at each minimum value.
（Volume : Counterclockwise）
7-3. Turn the COARSE and the FINE volumes clockwise at each maximum value.
（Volume : Clockwise）
7-4. Check the operation point of the Flow Switch at the ambient noise level.
Confirm that the FLOW lamp (left, Yellow) lights when no material is flowing.
Slowly turn the Fine volume counterclockwise and verify where the FLOW lamp turns off.
At this time, if the FLOW lamp does not turn off even when the FINE volume is turned to the middle
position, stop at the middle and turn the COARSE volume counterclockwise until the FLOW lamp
turns off.
7-5. Check the operation point of the flow switch at the signal level.
The FLOW lamp lights up when the specified amount of material flows at the specified speed.
Slowly turn again the COARSE volume counterclockwise while the material is flowing and verify
where the FLOW lamp turns off.
7-6. Set the COARSE volume to the middle between the flow switch’s operation point at the ambient
noise level confirmed in 7.4 and that at the signal level confirmed in 7.5.
7-7. If the flow is intermittent, use the ON-DELAY volume to set the no-detection and use the
OFF-DELAY volume to set the continuous-detection time.
８．Maintenance
Maintenance is not needed for the Flow Switch. Confirm the following items in periodical inspections.
8-1.Tightness of the bolts for the housing cover.
If these bolts are loose, rainwater or dust can enter from the space between the housing cover and
the case, resulting in a malfunction or failure.
8-2.tness of the lock nuts.
If these lock nuts are loose, the application facility may be affected.
8-3.Cleanliness of the transmitting face.
As aforementioned, microwaves have excellent penetration ability.
But on excessive amount of adhered matter may affect normal operations.
So the face must be periodically cleaned.
Note: Please note that the specifications or appearance may be changed without notice due to
modification of the Flow Switch.
Note: Matsushima does not take responsibility for any changes or modifications of the Flow Switch
made by the user or unauthorized personnel.
