TECHNICAL DATA
Operation
The Modulo controller receives continues readings of flow and up-downstream pressure and provides pneumatic pressure to the MSPC unit changing the pilot set point according to pressure & flow pressure & time functions. The pressure reducing pilot commands the hydrometer to throttle closed when downstream pressure rises above pilot setting, and modulate open when it drops below pilot setting. A standard PDA allows programming and data downloading.
