Biogas flowmeter with new possibilities
A new trend is on its way: more and more functionality is being demanded from the instruments. With the new possibilities of the OPTISONIC 7300 biogas flow meter, KROHNE responds to this demand from the market.
The biogas flow meter for measuring dry and wet biogas with variable composition is now also available with temperature and pressure sensors.
How? By making smart use of the ultrasonic flow measurement principle, we can also display other parameters of the medium to be measured. If you integrate two more sensors into the measuring tube, i.e. temperature and pressure sensors, then even more information is available. With these two additional parameters it is possible to calculate back from volume to standard conditions in addition to the medium speed (flow rate). The methane content in the biogas can also be reduced by measuring several parameters, such as the speed of sound of the gas in combination with the measured temperature, via the integrated (flow) computer.
As a result, both the biogas installation is monitored for production efficiency, as well as the amount of gas produced, and we can say something about the quality of the gas.
Once calibrated, the OPTISONIC 7300 measures with an accuracy of 1% for years without maintenance or recalibration. Together with extensive diagnostics, continuous monitoring is possible and the status of the measuring instrument is clear at any time.
Highlights:
• Insensitive to variable CO2 content
• Measurement of methane content
• Integrated volume flow calculation with optional pressure sensor
• Insensitive to corrosive components in gas such as H2S
• Wide measuring range, from 0 flow; high accuracy from 1 m/s
• Ex approval for zone 1
