Page 9: Overview
Chapter 1. OVERVIEW ■ Summary The MCF air flowmeter uses a µF (Micro Flow) sensor in its sensing unit. The µF sensor is a thermal flow speed sensor which uses proprietary technology. Integrating this ultra-miniature flow speed sensor with high-grade channel design technology has achieved high accuracy and wide rangeability. -

Page 21: Wiring
Chapter 3. MOUNTING AND WIRING ■ Wiring ● Cautions for wiring • Supply a power voltage within the specified range. • Keep the MCF wiring (conduit) away from power wiring or high voltage wires. • When connecting the connector, push the two parts together, and then tighten the nut by hand to 0.4 to 0.6 N m. - Page 22 Connect terminating resistors of 150 Ω±5%, 1/2 W min. at each end of the transmission line. The FG grounding must not be made at the both shielded wire ends but only at one location. Azbil Corporation ’s CMC10L001A000 can be used as a converter of the host station.
