Display units are the same as those of remote type digital flow switch for water (series PF2W3
).
Refer to page 16-13-19 for details.
Note 1) The system accuracy when combined with PF2W3
.
Note 2) Output system can be selected during initial setting.
Note 3) Without lead wire. (Add 20 g for the types of analog output whether voltage or current output selected.)
Note 4) The sensor unitis comformed to CE mark.
