The flow switch RIV170 is used to signal an alarm with an ON / OFF the passage of a fluid in a pipe.
This flow has a visual indicator of flow through large portholes.

It is used in a wide range of applications: chemical treatments, refrigeration, boilers, heating processes, cooling ducts, machinery, conveying fluids, water treatment, fire extinguishers, pumps fuel oil, lubricating oil pipelines, plant food, mixing processes, machine tools.
It can be constructed both with threaded ends that with flanged in stainless steel AISI 316.

Upon request, the flow switch RIV170 with visual indicator is available with IP66 waterproof case or ATEX explosion.

For sizing you must specify: fluid, specific gravity, viscosity, temperature, pressure, flow and operating desired point.
