* Key-operated Flowmeters are placed at the user site but require a purchased key, one per procedure, to operate the Flowmeter. Key-operated Flowmeters may require a key purchasing agreement in order to be placed. Non-keyed Flowmeters are purchased and have no restrictions on use. Regardless of the Flowmeter selected, Flowprobes are subject to their own limitations on the number of uses, depending on the family of Flowprobes being used.

** HT353C & HT354C Meters provide additional information on the print-out regarding CABG grafts when connected to a pressure input including: D/S, DF%, graft profile and patency assessment.


Specifications are dependent on the model and size of the attached Flowprobe or Flowsensor. Please see the corresponding Flowprobe or Flowsensor product page for more information.
