Nitto Seiko Mass Flow Meter
A mass flow metre called CLEAN FLOW achieves great performance and high dependability. By sensing the phase difference created by Coriolis in the measuring tube, it is able to measure mass flow directly. An easy-to-use capacitance touch panel is a feature of the high-functioning transmitter. A variety of indication articles can be put on the three LCD lines.
