Measurement and dosing in top quality Dosing meter OKtronic Oval wheel meter for precise metering Dosing controller DC 155 for comfortable handling Electro-pneumatic two-step valve shutoff Metering of highest viscosities (max. 100000mPas) Metering of non-conductive liquids No inlet or outlet section necessary Menu driven software configuration Characteristics The electro-pneumatic dosing meter OKtronic combines the precise metering of approved oval wheel meter, the intelligent elektronic and modern valve technology to a robust and universal applicable metering unit. Ergonomics With a comfortable keyboard, with large keys (22 x 22 mm), a clearly arranged display and the flexible functionality it is easy to realize simple as well as complex batch applications directly in hazardous area, without huge wiring expense to a e.g. panel room in safe area. Simple remote control It is possible to realize a remote control for the basic functions "START", "STOP", "RESET" Process monitoring The DC155 has a comfortable malfunction and disturbance monitoring system to monitor the sensor wiring and the flow. To avoid wrong warnings,it is possible to turn off the monitoring for a programmable delay time at the start up phase. This is also possible for over or under-run of limit values. Analog output The analog output of the DC155 has a 14 bit resolution and it can drive an impedance up to 600 W, respectively 1000 W , using the separate analog output supply option. MODBUS interface With the modbus interface it is possible to view process data (like actual filled amout, total amount, etc) on a DCS for instance. The operator can also
