Note:
• Before installing the flow meter, be sure to exercise flushing (cleaning the inside
of the pipe) to remove any foreign matter that may be present inside the pipe.
Residual foreign matter could cause output fluctuations.
• Make sure the fluid flow direction matches the flow-direction indicating arrow
mark (
ð
) of the flow meter. Otherwise, stabilized output cannot be obtained.
