POMOPTACC

Option: AccuBlend™ System, Automatic Gas Properties Control. Electric actuator to adjust the angular position of the piston in the POM, and thereby correcting the calorific value of the mixed gas. Actuator is installed on top of the POM valve. Price includes controller with PID characteristics (integrated in electronic signal processor of GraviBlend™-3/3E; see Note 1), which receives a linear analog signal (4-20 mA or 0-5V) from the Gravitometer and sends a control signal to the actuator (requires “Option: Gravitometer”).

Note 1: If the GraviBlend™-3/3E gravitometer is ordered together with the WB/POM system, we offer to integrate the electronic signal processor into the PLC of the WB/POM, and to upgrade the electronic operator interface to an 8-inch color LCD display with touch screen operator interface, at no additional charge. A further upgrade to a 10-inch Allen-Bradley PanelView-Plus is available at a nominal charge of US-$2,600.00.
