*1:In the actual flow measurement setting, the digits of the accumulated flow rate display, instantaneous flow rate display and pulse output vary.
*2: When displaying the instantaneous flow (NL /min), the main display (accumulated flow rate), sub-display (instantaneous flow rate [Nm3/h]), pressure (kPa) and temperature (°C) will not be displayed.
* Piping conditions:
20D or higher in upstream and 5D or higher in downstream for the 25A/32A models. (When using in the forward and reverse display mode, 20D or higher on both sides.)
10D or higher in upstream and 5D or higher in downstream for the 40A or larger models. (When using in the forward and reverse display mode, 10D or higher on both sides.)
