Visual flow confirmation — alone or combined with electrical switching. The 5-18 provides visual-only indication; the 5-19 adds a reed switch output for dual-function operation.
All products available in Polypropylene (PP), Acetal (AC), and Kynar PVDF (KR). No minimums. Ships Wednesdays.
All Series 5 flow switches and indicators share these electrical and mechanical ratings.
