*1) For digital flow switch with the unit switching function (For the type without the unit switching function, fixed SI unit [L/min or L, m^3, m^3 × 10^3] will be set. )
*2) The flow rate display can be switched between the basic condition of 0°C and 101.3 kPa and the basic condition (ANR) of 20°C, 101.3 kPa and 65% RH.
*3) A straight section that is 8 times or more the pipe diameter should be provided to the pipe on the IN side of the product. If not, the accuracy may fluctuate by ±5% F.S. or more.
*4) It does not include lead.
*5) The accumulated flow rate value is reset when the power supply is turned off.
*6) Switch output and accumulated pulse output can be selected during the initial setting.
*7) Window comparator mode: Since the hysteresis (H) will reach 3 digits, separate P_1, P_2 or n_1, n_2 by 7 digits or more. (In the case of OUT2, n_1 and n_2 will become n_3 and n_4, and P_1 and P_2 will become P_3 and P_4.)
*8) All flow switches comply with CE marking.
*9) For wiring and thread standard, refer to the instruction manual.
*10) Even in striving to improve the quality, products may have small scratches, smears or variations in display color and brightness, etc., that do not affect the performance, verified as conforming products.
