Specifications
Note 1) For the type with unit switching function [The type without the unit switching function will have a fixed SI unit (l/min, or l, m³or m³x 10³).]
Note 2) The high flow rate type is with CE marking. However, the linearity with applied noise is ±5% F.S. or less.
Note 3) Switch output and accumulated pulse output selections are made by button operation.
Note 4) The analog output operates only for real-time flow rate, and does not operate for accumulated flow.
Note 5) Flow rate display can be switched between the basic condition of 0°C, 101.3kPa and the standard condition (ANR) of 20°C, 101.3kPa, 65% RH.

Problem
A current of more than
80mA is flowing to OUT1.
The setting data has
changed due to some
influence.
The flow rate is over the
flow rate measurement
range.
Corrective action
Check the load and wiring
for OUT1.
Perform the RESET
operation, and set all
data again.
Reduce the flow rate until it
is within the flow rate
measurement range, using
an adjustment valve, etc.
Connectors
RESET Buttons
Pressing the UP and DOWN buttons
simultaneously activates the RESET
function.
This clears the unit when an
abnormality occurs and clears the
accumulated flow display to "0".
Indicates the selected unit.
The type without the unit switching
function will have a fixed SI unit
(l/min, or l, m³or m³x 10³).
Indicates the real-time flow rate,
accumulated flow, and set value.
Indicates the flow rate volume.
The blinking intervals change
depending on the flow rate value.
Since the connectors (female contacts) shown below can be used,
please refer to the respective manufacturers.
