3500 Armor-Flo meter with Limit Switch

In addition to the performance benefits of the 3400 Series flow rate meter, the 3500 Series Armor-Flotm includes switching capabilities. Adjustable flow switches provide positive indication of flow/no flow conditions or may be positioned to establish process limits. In either application the switch captures the indicator preventing movement until the flow rate is within the acceptable range.

The glass encapsulated reed switches are SPDT rated at 0.25 amperes at 120vac (1.5 amperes at 24vdc). This switch is appropriate for use in Class I, Division 2 areas.
