Description: Digital Flow Sensor
Weight: Approx 115 g
Footnotes: *1 Do not connect to the sides of units other than the DL-RS1 and FD-M. *2 The rated flow range indicates recommended operating range. *3 Flow under the zero cut flow will be displayed as 0 L/min. *4 - The repeatability is effective within the display range. Convert the F.S. (full scale) listed in the table according to the rated flow range. - The repeatability for FD-MH10A in the range of 20 to 30L/min is the double of the value listed in the table. *5 Maximum 20 mA for alarm output. When the total number of extension units is between 6 and 10, set each output current to 10 mA or less.
