自动化仪表供应商Endress+Hauser发布了一款新型的用于沼气测量领域的流量计——Prosonic B 200。该产品采用超声波测量原理,凭借不受水汽影响和甲烷浓度测量功能成为沼气测量领域的完美解决方案。传统的沼气测量多使用基于热式、差压、涡街和涡轮原理的流量计。由于沼气自身的特殊性,这些测量原理都存在各自的弊端。就热式流量计而言,沼气中多含有水汽,而水汽会对测量精度及稳定性产生严重的影响;就差压流量计而言,通常由于阻流原件的存在势必会产生压
Endress + Hauser, a supplier of automation instrumentation, has released a new version of the Prosonic B 200 for biogas measurement. The product is based on the principles of ultrasonic measurement and is the perfect solution to the field of biogas measurement thanks to its ability to measure water vapor and methane concentrations. Traditional biogas measurements use flowmeters based on thermal, differential, vortex and turbine principles. Due to the particularity of biogas, these measurement principles have their own drawbacks. In the case of thermal flowmeters, the biogas contains more water vapor, which can have a serious impact on measurement accuracy and stability. For differential pressure flowmeters, pressure
