Flow Switches

Switches support flow measurement, switching, control, or installation work in liquid, gas, air, water, and process systems. Products in this category span threaded plastic pipe flow switches, thermal dispersion liquid and gas flow switches, compact relay flow switches, heavy-duty paddle switches, trim-to-size paddle switches, and non-magnetic industrial flow switches.

Applications include pump protection, cooling water verification, HVAC hydronic loops, chemical lines, gas flow confirmation, filter monitoring, equipment interlocks, and alarms for low-flow or no-flow conditions. Products represented in the source data include Omega Engineering and Dwyer Instruments.

Applications include:

• Detect flow or no-flow states
• Protect pumps, heaters, chillers, and process equipment
• Switch relays or control circuits
• Use paddle or thermal dispersion measurement
• Match wetted materials to liquid or gas service
