The Inline style thermal mass flow switch assembly includes the flow sensing element, temperature sensing element, bridge amplifier/signal output board, transmitter enclo­sure, and flow section. The flow section is typically specified to match the user's flow conduit and is plumbed directly in the flow line. This design has the sensing elements mounted directly in the flow section for exposure to the process flow.

Inline flow switches are available in sizes from 1/4″ pipe through 4″ pipe and are provided with threaded male NPT ends as the standard mounting style. Optional end mounting styles may be specified, such as tube ends, tube end fittings, butt weld ends, flanged end configurations, etc. as required. Pipe sizes in excess of 4″ require insertion style thermal mass flow switches.

All of EPI's flow switches have two single-pole, double-throw relays for Hi/Hi, Lo/Lo and Hi/Lo capability. The contact closure is 5 amps @ 24 VDC and 115 VAC. Two LEDs are provided for verification that the Hi or Lo alarm has been triggered. The standard configuration has 316 Stainless Steel wetted parts (Hastelloy & Monel are also available) for a rugged, cleanable instrument designed for use in applications where corrosion, abrasion, high pressure or rough handling may be expected
