An ideal alternative to paddle wheel flow switches

Calorimetric flow sensors detect most fluids

Reliably detect the flow rate of water, oil, glycol and air in pipe sizes up to 16” diameter with the SA family of flow sensors.  The SA includes outputs for relative flow, flow velocity, flow rate and temperature.  The thermal technology is ideal for flow / no flow applications.

• Improve quality with proper flow and temperature of cooling water.
• Eliminate maintenance due to jamming and breaking of mechanical flow switches.
• Protect pumps from damaging run-dry conditions.

Because there are no moving parts to jam or break, the SA flow sensors eliminate the maintenance headaches of mechanical flow switches like paddle wheels, flappers, and rotometers.
