Katronic KATflow 150 Clamp-on flow meter

Katronic KATflow 150 is our go-to instrument for clamp-on liquid flow measurement.  This non-invasive flow meter incorporates a modular design with a variety of transducer types, output options and up to 2 measurement inputs with the single electronics enclosure.

Katronic KATflow 150 has the ability to accept Pt100 temperature sensor inputs.  This allows the instrument to be used as a heat meter for monitoring energy use.  Fluidic are experienced in providing energy surveys and can install clamp-on flow meters.  We offer the full instrument solution from product selection through to supply and commissioning.  Please contact your local office for more information.

As with all Katronic clamp-on flow meters, the KATflow 150 is equipped with an audible sensor positioning assistant.  The technology behind Katronic flow meters is time-of-flight.  This involves in sending and returning an ultrasonic pulse between both sensors.  In a 0 flow line, the time to send and return is equal.  In the direction of flow, the time to send the pulse is quicker than to return against flow.  This send/return time difference is proportional to flow velocity allowing the flow meter  to determine velocity and calculate volumetric flow against line diameter. The audible positioning assistant ensures accurate and simple installation to ensure you have the absolute best accuracy of measurement possible

Katronic KATflow 150 Common Applications:

  • Cooling systems
  • Fire-pump control
  • Effluent metering
  • Dosing applications
  • Water for injection / demineralised water applications (where magflow wont work)
  • Oil flows, fuel consumption etc
  • For project style work, in large BMS systems etc, consider the KATflow 100
