Our CLASSIC models can be used as either a flow switch, level switch or interface switch. There is no need to specify the switch function at time of order. The CLASSIC can be installed as a flow switch today and configured by the customer to be a level controller tomorrow. The CLASSIC can be used in air, gases, liquids or slurries. With an array of sensor sizes, materials and configurations available including insertion and in-line, threaded or flanged and retractable packing gland styles, a CLASSIC model will fit your application.

The Kayden line of products is based on the thermal dispersion principle of operation. Though often referred to as a thermal dispersion flow switch, thermal flow switch, liquid flow switch or Modbus flow switch our products can also be used in level and interface applications. Some level applications are: level controller, tank level, high level alarm, low level alarm, wet/dry alarm and various other applications involving flow alarms. Another common application is interface control, especially those requiring an oil water interface switch. Kayden switches are also commonly used in pump protection, seal leak detection, and flow/no flow applications.
