The Argonne National Laboratory has developed and tested an acoustic flow/no-flow monitor for the char return line of the BI-GAS pilot plant. The indicator has operated successfully for the last three years. It has been observed that the strength of the microphone signal was related to the amount of char in the line. In a recent experiment at BI-GAS this observation was further explored, and it was found that the signal is related to the char valve opening in the frequency range of 1 to 20 kHz. This is a clear indication that the flow/no-flow indicator can be upgraded to a density meter and consequently to a true mass flowmeter. This can be done by installing another flow/no-flow indicator upstream or downstream of the existing one and cross-correlating the two signals.
