*1 Battery life is five years (under an average environment temperature of 20°C). The batteries can be replaced on-site.
*2 The type of gas setting can be changed on-site.
*3 The actual flow rate stands for the volume flow rate (unadjusted flow rate).
*4 The communication specifications are available on our product website.
*5 Moving average can be configurable (Select from 1 to 16 times; Standard setting is 4 times).
*6 The expression “simple” stands for the correction of a pressure value using an arbitrary value (fixed value).
