【摘要】：正自動化儀表供應(yīng)商Endress+Hauser發(fā)布了一款新型的用于沼氣測量領(lǐng)域的流量計——Prosonic B 200。該產(chǎn)品采用超聲波測量原理,憑借不受水汽影響和甲烷濃度測量功能成為沼氣測量領(lǐng)域的完美解決方案。傳統(tǒng)的沼氣測量多使用基于熱式、差壓、渦街和渦輪原理的流量計。由于沼氣自身的特殊性,這些測量原理都存在各自的弊端。就熱式流量計而言,沼氣中多含有水汽,而水汽會對測量精度及穩(wěn)定性產(chǎn)生嚴重的影響;就差壓流量計而言,通常由于阻流原件的存在勢必會產(chǎn)生壓
[Abstract]:Endress Hauser, a supplier of automation instruments, has released a new type of Flowmeter for biogas measurement-Prosonic B 200. The product adopts the principle of ultrasonic measurement and becomes the perfect solution in the field of biogas measurement with its water vapor-free and methane concentration measurement function. Traditional biogas measurements use flow meters based on thermal differential pressure vortex street and turbine principles. Due to the particularity of biogas itself, these measuring principles have their own disadvantages. As far as thermal Flowmeter is concerned, there is water vapor in biogas, and water vapor will have a serious effect on measurement accuracy and stability. In the case of differential pressure Flowmeter, it is usually necessary to produce pressure due to the existence of blockage elements.
