4 kinds of mixed fluids (brands) of different component substances or compounding
ratios can be made.
Conductivity correction signal:
4-20mADC (corresponding to conductivity level of 0 to 10mS/cm)
To perform conductivity correction, prepare a conductivity meter and install it in a place
where conductivity can be measured correctly and steadily and enter the obtained
conductivity correction signal here.
Update cycle of density measurement output and display: Approx. 1 second
Moving average:
Rate-of-change limit: Rate-of-change width: 0.00 to 9.99%TS, Count: 0 to 99
Additives correction function:
Arresters:
Operation console (inside the converter):

Density measured values are output as moving averages of 1 to 99
measurements made approximately every 1 second.
This output is used when the averaged output is required for density control
or other purpose.
This is a function to limit a sudden output change by eliminating signals that
cause sudden output changes in such cases as when a sudden density
change occurs or air bubbles are mixed in the liquid to be measured. You
can set the condition of the rate-of-change limit using the rate-of-change
width and how many times the change occurs (count).
Capable of handling up to ten brands, this function performs the sensitivity
correction appropriate to the additives type and compound ratio in
accordance with the parameters that are registered in advance.
Mounted as standard on the current output and AC power supply lines.
Used for verifying, changing and manipulating various data.
Five control switches
Display: LCD of 4 lines by 20 characters (dot matrix)
100 to 240 VAC; 50/60 Hz
(Allowable power supply voltage: 85 to 264 VAC)
Approximately 35 VA(240VAC)
