B. Modes of Operation
C. Filter Settings
To record instantaneous ow: set the ow
output [Filter] to a frequency at least 10
times the rate of ow pulsation. The digital
sample rate for data recording should be
set to a minimum of 3 times the application
frequency.
D. Analog Outputs

Flow Modules output analog signals in the range of -5 volts to +5 volts that are compatible
with most A/D (analog-to-digital) converters of Data Acquisition Systems. The back panel analog outputs
generated by the TS410 Module are listed in the table below:
TS410 Module: Functions & Controls
NUMBER TERMINAL NAME VOLTAGE DESCRIPTION
12 Sync In In/Out required for operation; Multi-Module synchronization
11 Sync Out In/Out required for operation; Multi-Module synchronization
10 GND Ground
9 GND Ground
8 Rec Amp 1 0 - 4 V Quality of ultrasound transmission for testing Sensor functionality, acoustic coupling
or blockage of ultrasound by air or other impedance mismatch. Can be used in bubble
detection by indicating a drop in signal as air passes through the Flowsensor. 2 V = 100%
7 Rec Amp 2 0 - 4 V Same as Rec Amp 1 for the second pair of transducers. 2 V = 100%
6 Phase 2 B ± 5 V Same as Phase 2 A but offset by +4.5 V or -4.5 V
5 Phase 2 A ± 5 V Same as Phase 1 A but for the second pair of transducers
4 Phase 1 B ± 5 V Same as Phase 1 A but offset by +4.5 V or -4.5 V
3 Phase 1 A ± 5 V Acoustic velocity of uid used in ultrasound indicator dilution studies
2 Mean Flow ± 5 V Average volume ow output, ltered at 0.1 Hz
1 Puls Flow ± 5 V Instantaneous pulsatile volume ow output, ltered at 10, 40, or 160 Hz depending on the
Module front panel [Filter] setting. Output defaults to 160 Hz if 0.1 Hz button depressed.
All PXN and PXL Sensors have two pairs of transducers. Flow data is determined from the combination of both pairs while phase and
received amplitude data are separated by transducer pair.
