SonoQ-GP30Demo
Introduction
The ultrasonic flow meter, based on the TDC-GP30 from ACAM/ams is realized as a
demonstration system for aqueous media and is suitable for integration into
equipment, machines and tools. With this demonstrator it is possible to practically
evaluate the extensive possibilities of the GP30 immediately and to define own
specifications for custom specific design for a flow meter. An outstanding tool for a
significant facilitation of introduction into the world of ultrasonic flow metering is now
available.
The demonstration system consists of a flow piece made from bras with a standard
process connection 1”, ultrasonic transducers and a matched GP30-based electronic
board. The system is fully operational and compensated for a flow range from 1,0 to
75 l/min with a media temperature from 5°C to 90°C. The lowest detectable flow is
around 0,2l/min, enabling the use as a leakage detector or drop detector.
The TDC-GP30 demonstration system is working as a complete frontend solution
with integrated digital signal processing unit (32-Bit Microprocessor) up to a
calibratable output. A real single chip solution is provided, including a digital volume
flow output via UART, pulse and SPI and allows the generic standard MCU to be
focused to the communication management of the sensor as for example
visualization of results or wireless interfaces.
Custom specific changes for other liquids and flow- ranges may be performed on
request.

The measurement method is widely independent from color, temperature and
electromagnetic properties of the fluid.
The measurement method incorporating the fast time-of-flight evaluation is
working almost without time-loss and herewith superior to turbines or thermal
sensors. Even pulsating flows (e.g. membrane pumps) are capable to
measure.
No moving parts, no damage caused by high flow volumes larger than
specified.
High long term stability.
Free choice of installing position.
Detection of empty flow section (air) and surveillance of floe direction.
Leakage detection starting with a flow of drops in a DN20 system.
Possibility of calibration.
Principle of Operation
The flow meter is using the ultrasound time-of-flight (ToF) method. Here, the flight
time of an ultrasonic pulse is gathered in the direction of flow and in the opposite
direction. Using the difference of both times, the speed of flow and with this, the flow
volume is calculated. Usually a number of raw results, gathered by different
customized algorithms are evaluated before post processing.

PC-Software
By connecting the USB-interface with a PC (Windows 7 (x86/x64) or Windows 8
(x86/x64)), the interface-box is recognized as a virtual COM-port.
Starting the software, following window opens:
By help of the following dialog, the COM-port needs to be specified (here COM5,
may change depending on system). By pressing the button “Connect”, the interfacebox will be connected with the PC.
The upper graph will display the measured flow. The bottom graph may display up to
three differences of ToF-results and the mean of these results.

The amplitudes of the received ultrasound signals, the speed of sound of the liquid
and the temperatures (Pt1000) are visible by digital displays. It is possible to select
arithmetic mean (n=10, n=20, n=50, n=100) for flow and ToF to match the response
time.
All displayed results may continuously be exported by pressing the button “Save” into
a selectable txt-file for further processing.
