KMS 6300 – Ultrasonic clamp-on flowmeter


Ultrasonic clamp-on flowmeter for flow measurement of liquids

  • Stationary device for installation at any location without process interruption or need to cut pipes
  • Up to +200°C / +392°F
  • Robust stainless steel sensor rail for pipes DN15…4000 / ½…160″
  • 4…20 mA, HART®7, Modbus, FF, Profibus-PA/DP


The KMS 6300 is an ultrasonic clamp-on flowmeter designed for permanent installation. It excels in accurately measuring the flow of both conductive and non-conductive liquids in scenarios where inline measurement may not be practical or desirable.

The flowmeter is ingeniously crafted, featuring a stainless steel sensor rail with two integrated transducers. For larger pipe sizes, an option is available with a sensor rail set comprising two rails, each with integrated transducers. You’ll find a wall-mounted or field-mounted ultrasonic signal converter in both configurations for added convenience.

Its robust clamp-on rail sets this flowmeter apart, offering exceptional flexibility. This rail can easily attach to virtually any pipe, accommodating sizes up to DN4000 (160 inches).
