*1) For digital flow switch with unit switching function. (Fixed SI unit [(L/min, or L, m³ or m³×10³)] will be set for switch type without the unit switching function.)
*2) Flow rate display can be switched between the basic condition of 0ºC, 101.3 kPa and the standard condition (ANR) of 20ºC, 101.3 kPa, and 65% RH.
*3) The piping on the IN side must have a straight section of piping whose length is 8 times the piping diameter or more. If a straight section of piping is not installed, the accuracy may vary by±5% F.S. or more.
*4) Accumulated flow rate is reset when the power supply turns OFF.
*5) Switch output and accumulated pulse output can be selected during initial setting.
*6) Window comparator mode - Since hysteresis will reach 3 digits, keep P_1 and P_2 or n_1 and n_2 apart by 7 digits or more. (In case of output OUT2, n_1, 2 to be n_3, 4 and P_1, 2 to be P_3, 4.)
*7) For details about wiring and thread type, please contact VPC.
*8) Any products with tiny scratches, smears, or display color variation or brightness which does not affect the performance are verified as conforming products.
