Operation using the data setting device Azbil Corporation

Setting or changing low flow cutoff: [CUT-OFF] function
Introduction
When a fluid in the detector is flowing extremely slowly, the converter judges that the
fluid is stationary and outputs a signal (4 mA DC in case of analog output) equivalent
to a flow rate of zero. The value, which becomes the threshold of this judgment is
called “low flow cutoff”.
The low flow cutoff is set using a percentage over the upper range value of the flow
rate measurement range set by the URV.
Procedure
Use the following procedure to set low flow cutoff.
m CAUTION
The low flow cutoff is a factor of extreme importance that affects the operation of the entire
control process. Define the range to be controlled and start the setting carefully.
