1: Please refer to the chart of measurement range of ethylene glycol aqueous solution on page 32 . Measurement is possible as long as
the fluid does not corrode the wetted parts, and viscosity is 3 mPa

s (3 cP) or less. Be aware that water leakage may happen due to
internal seal shrinkage or swelling depending on kinds of fluid. Refer to the "Applicable fluid list" on page 31 .

2: The operating pressure range and proof pressure vary depending on the fluid temperature. Refer to the chart on page 35 .

3: The response time is when the set value is 90% in relation to the step input.

4: If a reduced piping diameter or the piping layout cause a restriction, it may not satisfy the specifications.
