Please see below picture for example the software show mass total is 147.9g but we got the beaker increasing 300g . Also please see the second picture we could calculate mass total approximately by average flow rate and elapsed time the result shows it is close to measured value so I guess maybe the algorithm of calibration software has some problems. In addition ,I noticed that the two software interface show the fuel rate is the same when the actual fuel flow is the same but in fact the unit of two software is different (coriolis is kilogrames/hour but calibration software is Ib/hr ),maybe the cause of difference is this .</description><category domain="https://emersonexchange365.com/worlds/china_/field_instrumentation_-_/tags/_D89AC651EA4E68882168C651_">高准仪表校准</category></item><item><title>Forum Post: 艾默生超声波流量计应用咨询？</title><link>https://emersonexchange365.com/worlds/china_/field_instrumentation_-_/f/field-instrumentation-----forum/2210/thread</link><pubDate>Fri, 12 Oct 2012 05:32:00 GMT</pubDate><guid isPermaLink="false">cd40bb2b-3d49-4868-939d-417119b40291:6ed15ac9-628c-4045-af16-7f8776bd6610</guid><dc:creator>王敏辉</dc:creator><description>要对现在使用的两台孔板流量计进行改造，想采用超声波流量计替代。 对超声波流量计基本要求条件: 管径6&amp;quot;、法兰：ANSI CL150LB RF、碳钢、供电DC24V、输出信号：4-20mA、二线制、防爆、IP67、外表要防腐以上。 基本工况：介质：VCM（氯乙烯气体、有腐蚀性）（带少量可能会结垢的杂质） 温度：不大于60度 压力：不大于5bar 流量:不大于500Nm3/h 请问有没有符合上述基本要求的超声波流量计(控制使用非计量级别)？</description><category domain="https://emersonexchange365.com/worlds/china_/field_instrumentation_-_/tags/_858DF058E26C416DCF91A18B_">超声波流量计</category></item><item><title>Forum Post: Roxar Downhole Flown Sensor 咨询 - 油田井下的流量传感器及含水量传感器咨询?</title><link>https://emersonexchange365.com/worlds/china_/field_instrumentation_-_/f/field-instrumentation-----forum/2124/roxar-downhole-flown-sensor--</link><pubDate>Fri, 14 Sep 2012 05:32:00 GMT</pubDate><guid isPermaLink="false">cd40bb2b-3d49-4868-939d-417119b40291:048f0ced-ba6d-4957-829d-1148a4607671</guid><dc:creator>王敏辉</dc:creator><description>想咨询一下是否有可用于油田井下的流量传感器以及含水量传感器？我在贵公司网站看见一款传感器（见附图），比如Roxar Downhole Flown Sensor。不知道贵公司是否有相关的产品，可供应用于井下？请赐教！</description><category domain="https://emersonexchange365.com/worlds/china_/field_instrumentation_-_/tags/_B96C3075954E0B4E8476416DCF91204F1F616856_">油田井下的流量传感器</category></item><item><title>Forum Post: A question to Rosemount 3095MV [From Customer]</title><link>https://emersonexchange365.com/worlds/china_/field_instrumentation_-_/f/field-instrumentation-----forum/2100/a-question-to-rosemount-3095mv-from-customer</link><pubDate>Wed, 05 Sep 2012 07:51:00 GMT</pubDate><guid isPermaLink="false">cd40bb2b-3d49-4868-939d-417119b40291:afb9d003-7aef-440c-833c-5a1c1dcb9205</guid><dc:creator>王敏辉</dc:creator><description>DCS always prompt a alarm “Flow is above upper internal limit”.
