Thermal flow switches with no moving parts replace mechanical switches

Reliably detect the flow of liquids, gases and even some solids with the SI flow sensors. The thermal technology is ideal for flow / no flow applications and for very low flow applications using a low flow block accessory.

Outputs include analog flow representing 0…100% of taught flow rate and switching outputs for flow and temperature.

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