Transonic HT331-FT - HT300(-FT) Series Compatible Flowmeters

10 AU-OPR-AureFloFT-EN,
Rev H
DIGITAL FLOWPROBE/FLOWSENSOR IDENTIFICATION
Probe identication and calibration parameters are programmed on an EPROM housed inside the
Flowprobe/Flowsensor connector.
COMPATIBLE FLOWSENSORS
These Flowmeters accept a range of HQ- Series Flowprobes/Flowsensors for intraoperative surgical use. See
Probe specication sheets or your local Transonic
®
representative for models, sizes and recommended uses.
FLOWMETER INPUTS
Two 1/4” Phono Jack connectors are provided on the rear panel as auxiliary input for the Pressure and ECG
signal. They accept a signal range of ± 5 Volts.
USB OUTPUT PORT
Electically isolated output connector meeting IEC60601 patient isolation. For connection to the AureFlo
®
Monitor. The ± 5V analog Flow signals and ECG signal are digitized at 100 Hz sampling rate with 12-bit
resolution. Data is supplied at 19200 Baud with 8 data bits, 1 stop bit, and no parity for use with FlowTrace
®
software.
ULTRASONIC FREQUENCY/PARAMETERS
The ultrasound output level of the Flowprobes/Flowsensors is factory-set and does not incorporate any
interactive system features. These settings are made using “ALARA” principles (As Low As Reasonably
Achievable), and are orders of magnitude below the FDA “preamendment levels,” the USA insonication
safety limits. These settings satisfy the requirements of IEC 60601-2-37 for exemption from Mechanical
Index (MI) and Thermal Index (TI) reporting during use.
● Transducer excitation: Burst of 10 to 24 waves (probe size dependent).
● Transducer excitation frequency: 900 kHz to 9.6 MHz (probe size dependent).
● Transducer excitation rate: 900 Hz to 14 kHz (probe size dependent).

Device testing has shown that measurements are well below theoretical maximum values. Measurement uncertainties did not
exceed 30%.
