Anderson Negele - Calorimetric Flow Switch

  • Caliormetric Measuring Principle
  • Measuring Range 10…300 cm/s
  • Operating Pressure Max 60 bar
  • Approvals: FDA; EHEDG; 3-A

Product description

Calorimetry is the industry standard for flow switching/monitoring in food processing, utilising pulsed heating technology to determine a flow rate these sensors are lower cost option for flow monitoring, where more expensive and accurate options are simply unnecessary. The Anderson Negele FTS is built to the highest standards, is made completely from stainless steel and is designed specifically for hygienic applications as you would expect. With a flow optimised tip design to reduce the probes impact on media flow, the FTS also has a short response time and is insensitive to temperature shocks in your system.


The FTS also has a self protection built in, should it see high temperatures to protect it against thermal damage. It turns itself off and has a self reset once the temperature has reduced to a safe level. With an optional digital display to show you what percentage of your flow range is taking place in your application, there is a local indication of when the desired flow rate has been reached via an LED and the device has a switched PNP output for feeding in to your PLC.


Application Examples:


  • Flow monitoring in pipes from DN 25
  • Dry-run pump protection
  • Filter monitoring
  • Agitators
  • Cooling loops
  • Suitable for highly pure, aqueous media without particles or solids (e.g. ultra-filtered media, cola)
  • FDA Certified
