The standard value is the burst pressure at room temperature multiplied by the burst pressure reduction coefficient at 200℃ (180℃). When using it, we recommend operating it at 1/2 to 1/5 of the standard value.

±1% of R.D. * 10% or less of the measured flow rate range: ±0.1% of F.S.
"Instantaneous flow rate accuracy calibrated with pure water at 20°C (room temperature at 25°C) and stable flow rate.
