The AS 8 shows the flow rate of component A and B and the mixture ratio A/B. • The different indications are switched by the keys �¡F1 , �¡F2 and �¡F3 . • For each volume counter a density factor can be input. • One square-wave signal is required of each volume counter. The input signals are filtered, converted and processed by the microcontroller to give a mixture ratio. • The settings are made using the three keys on the front panel. The input values are arranged in menus. Functional Characteristics AS 8 - V2F • Two relay contacts, an analogue output or an RS 232 interface are available for additional external processing. • The integrated 24 VDC transducer supply enables the direct connection of the volume counter. • The type AS 8 series measuring devices are available as built-in control panel units, as bench units, or as 19" rackmounted units.
