New options for this biogas flowmeter

By Chemical Engineering |

Krohne Messtechnik

The Optisonic 7300 Biogas ultrasonic flowmeter (photo) for the measurement of dry and wet (raw) biogas with variable composition has been updated. Besides the standard temperature sensor, it now features an optional pressure sensor, which is mounted on the flow tube. In combination with the integrated flow computer, the additional sensor provides for advanced biogas measurement. A temperature sensor in combination with the measured velocity of sound enables direct measurement of methane content via calculation of the molar mass. By using an additional pressure sensor, Optisonic 7300 Biogas devices can also provide calculation of gas flow volume in standard conditions. The meter is available in line sizes 2, 3, 4, 6 and 8 in. (DN50, 80, 100, 150 and 200). — Krohne Messtechnik GmbH, Duisburg, Germany
