          *1 The models with “A” at the end of the name have additional functions such as display averaging.
          *2 The rated flow range indicates the range that is supposed to be used in general.
          *3 The rated flow range indicates recommended operating range.
          *4 Can be used within the display range as well as within the rated flow range.
          *5 Flow under the zero cut flow will be displayed as 0 L/min.
          *6 When it is 0.05, the display flow can be set in 0.05 increments between 0.15 and 0.5 L, and set in 0.01 increments for values above 0.5 L.
          *7 The repeatability for FD-M5AT (P)/Y (P) is ±7.5% of F.S. at a response time of 0.5 s and ±5% of F.S. at a response time of 1 s.
