Page 5: Installation
4. Installation The mounting part of the Flow Monitor is a G1 screw. Install the Flow Monitor either horizontally or vertically with the use of the G1 locknut and packing provided with the device. If there is any concern about the screw loosening, apply liquid gasket. If the Flow Monitor is to be used outdoors, attach a rain cover or similar protective cover to minimize the entry of rain water. -
Page 6: Flow Monitor Installation Conditions
<How to install so that adhesion and accumulation of transported materials is minimized> Install as shown in Fig. 4, so that the transmitting and receiving surface is flush with the container wall (tube, pipeline, etc.). If installation shown above is not possible, install a shield made of a material such as low-permittivity Teflon or ceramics to allow microwave transmission. - Page 7 5-2. Pneumatic transportation Applications Flow Monitor Length: At least 10 times Length: At least 5 times the pipe diameter the pipe diameter Air flow Metal piping Important:Metal pipes must be used for the equipment piping. ！ Be sure to secure the required heights for installation.

Page 8: Wiring
6. Wiring • Use a cable of 1.25 mm to 2 mm diameter, and suitable for the environmental conditions in which it is to be used. • Connect wires only to the AC (power supply) and to 4 mA to 20 mA (current output) terminals. Caution: Do not connect unused terminals, as this may result in a Flow Monitor failure. -
Page 9: Operation
7. Operation The display window on the Flow Monitor panel functions as a measurement display window (for checking measured values) and a setting window (for entry of parameters), and must be operated in accordance with each situation. The window operation procedures and indications on display are described below. <Measurement Display Window>... - Page 10 7-1. Setting Zero and Span There are two methods, automatic and manual, to enter and set the zero and span values: Use either method according to the situation. 7-1-1. Manual Entry and Setting Method (a) Setting Zero Check and record the value of the arithmetic processing result indicated under no-load conditions (nothing is flowing inside).
- Page 11 7-1-2. Automatic Entry and Setting Method With the automatic entry and setting method, data measured within the sampling time (which has been set to any desirable value within the setting range) is calculated. The zero and span settings are automatically entered and stored to reflect the calculation results. Note: The default setting for the sampling time is one minute.

Press [MOD] With the moving average setting on display, enter a value to be set. three times. The numeric character which is flickering can be changed. Use [ ] to change the flickering position, [ ] to change the numeric character, and [STO] to store the entered value.
