3.1 Yieldmaster
The Yieldmaster is an analysis system for the simultaneousmethane (CH4) and volume
determination. The biogasanalyzer Yieldmaster is a highly developed measuring system con-
sisting of microprocessor controlled infrared-gassensors, precision volumenometers (Mil-
liGascounter®) and the related BlueVis bioprocessing software. It isconsisting of up to 12
sets of BCP-CH4 sensors(other sensorsfor CO2, O2, EtOH, H2also addable) and the same
number of MilliGascounters. The CH4 concentration will be detected by the BCP-CH4
sensors and the produced volume will be detected by the MilliGascounter.
The CH4 sensorsBCP-CH4 are connected to a multiplexer boxBACCOM12 for the meth-
ane measurement inside the vessel. Alternatively, the sensorscan be connected with power
supply for each sensor and USB adapter. The MilliGascounter are connected to the Coun-
terBoxfor the detection of the volume. The CounterBoxwill be connected to the BACCom12
for the power supply and the data transfer. Alternatively, the CounterBoxcan be connected
with power supplyand USB adapter directlyto the PC. The BACCom12 will transfer the meas-
urement data of the Methane and the volume to a PC. The BACCom12 can be connected to
a PC via a serial connection or an Ethernet connection. The BACCom12 also can be integ-
rated into your local area network (LAN) by the Ethernet connection.
Every MilliGascounter isprotected by a one-wayvalve. This device secures that no fluid from
the MilliGascounter could be sucked into the fermentation vessel due to change of pressure
during longer experiments. During the experiment, Methane is produced inside of the fer-
mentation vessel.
