NOTES

❑ Do not put a signal cable adjacent to other power lines.

❑ Inside diameter of process piping and fitting is to be more than that of flow path nozzle.

❑ Installation is to be made at the place free from the influence of external magnetic field which affects the property.

❑ Use this flowmeter where there is no stagnation of air around the wheel and also in the state of water filled up.

❑ Avoid the air blow since wheel and shaft may be damaged.

❑ The upstream straight runs of more than 10 D ( D: inside diameter of pipe) is recommended when uneven or whirling flow is expected.

❑ Keep body and process piping warm, and do not prevent the ventilation between heat insulation plates.
