2) Quick Start Guide
This section describes how to quickly set up the AS6040-DK, establish basic operation and make
measurements.
It is crucial to install the software before connecting the evaluation kit to your computer:
https://www.downloads.sciosense.com/as6040/
•Unzip the package to the desired directory, open directly “UfcEvaluationSoftware.exe” and
follow the instructions on the screen.
•Connect the PICOPROG V3.0 to the computer when requested, using the USB cable. And
connect the board to the PICOPROG using the DB15 connector cable.
•Connect your spool piece to US_UP and US_DOWN. US_UP fires upstream, means versus flow.
US_DOWN fires downstream, with the flow.
The following screen will appear:
Figure 2 : Opening Page
•Verify that the right device is selected.
•Select one of the ready configuration files, press “Load config” and then on the left “Write
•Next, open our configuration AS6031_water_meter_Demo_FHL.cfg and download it into the
chip, pressing “Write Config”.
•Press “Start Measurement” to begin measuring.
A detailed description of the UFC Evaluation Software I given in a separate document:
Clear the reset and error flags by pressing the buttons at the lower right. MCT Count Low and High
should blink while the measurement is running.

3) Hardware Description
Introduction
The AS6040-QF_DK_RB board, shown in Figure 3, is a front-end for a water or heat meters. The
transducers and temperature sensors are directly connected to this board. It comes with a 32.768
kHz quartz (X2) and a 4 MHz ceramic oscillator (X1).
Figure 3:
AS6040-DK_RB
Communication Interface
The PICOPROG device is a USB-to-SPI converter box that interfaces all UFC evaluation systems. The
PICOPROG is registered by the operating system initially as “PICOPROG v2.0 unprogrammed”. As
soon as the UFC evaluation software starts, a special firmware is written into the PICOPROG to
handle the SPI communication with the AS6040-QF_DK_RB. The PICOPROG is now listed as
“UNIPRO” in the device manager. For SPI communication only, PICOPROG version 2.0 is sufficient.
The flat connector connecting the PICOPROG and the AS6040-DK_RB includes the power lines and
the SPI communication lines. VCC_LEVEL is the voltage feedback for the PICOPROG level shifters.
4) Measurements in Practice
This section describes how to set up a gas flow measurement and shows some sample results of a
real gas meter spool piece. Configuration example AS6040_gas_200kHz_DLY.cfg is used as basis.
The example is built around 200kHz transducers from Jiakang in a distance of about 5 cm.
The example configuration likely needs to be adjusted to the customers setup. The most
important parameters are:
—— VCC
—— GND
—— VCC_LEVEL
—— -
—— SSN
—— MOSI
—— SCK
—— MISO
—— INTN
—— GND —— TPI_GND2 —— TPI_GND1 —— TPI_M2_A —— TPI_M2_B —— TPI_M1_A —— TPI_M1_B

●Fire pulse frequency
●Number of fire pulses
●Number of TOF hits
●Method for the start hit definition
●PGA gain of receiving amplitude
●Amplitude measurement
●Charge Pump Voltage
●Measurement Rate
In general, we recommend to have a look at the receive signal by means of an oscilloscope. This
clearly helps to find the right settings.
4.1 Measure Receiving Amplitude with Oscilloscope
If the signal is measured after the internal PGA stage there is no influence of the probe capacitance
to the measured time values. You can measure the receiving amplitude at test point TP4, which
connects to pin pin 17, COMP_IN.. In Figure 31 this points is marked. Another probe should be
connected to US_UP for the trigger signal. When looking at minimum noise then this probe of
course needs to be removed.

The on-board matching resistors R9 and R12 with 330 Ohm are a good fit for the tested
transducers. For other transducers it might be necessary to adopt the values.

6) Reference Modules and Transducers
Modules
ScioSense has a close cooperation with Qingdao iESLab to support customers with complete
ultrasonic flow modules for water and gas. For water, iESLab offers pipes made of brass and made
of plastic and modules can be ordered un-calibrated or calibrated. The gas meter modules are
made of plastic and come un-calibrated, because the final housing will have a major impact on the
calibration.
Gas Meter Modules
Those residential and industrial modules come with tubes made of plastic and the electronics are
based on AS6031.
