Brand New Arag Wolf, T5 Flow Meter 5-100L/Min M-F. WOLF paddle flow-meter – T5 fork connector for control units. The “TWIST” system is the peculiar feature of WOLF flow meters. ARAG R&D department has designed a quick-release system that does not require any tools and allows paddle cleaning, which is important considering that paddle usually collects any sediments of the chemicals contained in the fluids used for agricultural purposes. Thank you for looking.
