Krohne’s Optisonic 7300 2-beam ultrasonic measuring device determines the flow of process gases with maximum precision and longevity. Thanks to the newly designed titanium sensors and innovative signal processing, process gases with different and changing compositions as well as noise no longer lead to measurement errors. Once the unit has been calibrated it measures for years, without maintenance or subsequent calibration, with an accuracy of 1% of the measured value. The robust design and the wide range of applications make using the device particularly cost-effective.
Precise even in difficult situations
The Optisonic 7300 makes the flow measurement of gas even more precise than before. The ultrasonic method of flow measurement has always been considered superior to traditional measuring techniques such as orifice measurement or measuring with turbine meters, because it does not cause pressure loss and is maintenance free. Only fluctuating process conditions and external sources of sound such as valve noises led to measurement errors, but those things are now a thing of the past. Thanks to the particular material properties and the special damping technology of the new titanium sensors, the noise waves are perfectly focused and innovative signal processing eliminates the errors. This means that the device can now be used where previously only traditional measuring techniques would work successfully.
Durable and reliable
Following the initial calibration, the device provides exact measuring results with an accuracy of 1% without maintenance or subsequent calibration. This holds true for gas temperatures up to 180°C and pressures up to 150 bar. It also contains a flow calculator for pressure and temperature compensation to calculate the standard volume.
The Optisonic 7300 offers cost-effective operation thanks to its large dynamic spectrum and operational readiness as regards gas composition, density, pressure, temperature and volume flow.
