5-1 Installation place
①This equipment is designed for indoor use.
Never install the equipment in a place where it is likely to be wetted by water or rain. The
equipment may fail. Install the equipment in a place where sufficient ventilation is provided
and changes in temperature and humidity are minimal.
②Install the equipment in a place free of vibration and impact.
③Do not use the equipment under direct sunlight or at high temperature/humidity.
④Install the equipment in a place free of dust.
⑤Install the equipment in a place free of corrosive gases.
⑥Install the equipment in a place free of a strong electric/magnetic field.
⑦After installation, be sure to conduct leak test on piping.
⑧Install the equipment in a place where the operating temperature is 15 to 35℃.
The use of the equipment in a condition deviating from the conditions described in the
specifications is a cause of failure.

5-3 Precautions for piping
①The measuring tube must be filled with measuring fluid.
②Avoid such piping as fluid flows downward.
Bubbles in the measuring tube are a cause of deterioration of the accuracy.
③Be sure that the length of piping in the upstream is longer than 10D and the length of piping
in the downstream longer than 5D.
④Be sure that the flow direction matches the arrow shown on the body.
⑤When a flow rate adjust valve is to be installed, it is recommended that it be installed on the
secondary side of the meter.
If it is installed in the upstream, bubbles may be produced due to pressure drop to cause
deterioration of the accuracy.
⑥For connecting tube joints, follow the procedures furnished by the manufacturer.
During connection, hold the tubes to prevent breakage.
