烟气流速测量技术
ENVEA的创新 ProPitot™ 测量技术是一种平均皮托管技术，为工业烟囱提供具有代表性的高质量和可靠的烟气速度测量，用于监管流量和质量排放报告 (kg/年)。
这种平均皮托管技术能够:
- 在广泛的排放监测应用中提供具有代表性的烟气速度、压力和温度测量
- 污染物测量与参考条件的实时归一化 (STP/NTP)
- 符合QAL 1的欧洲监测标准EN 16911-2 和 EN 15267-3，并支持美国EPA PS-6（CFR40第75部分）Flow CEM
工作原理
ENVEA的创新ProPitot™ APF 平均皮托管技术是根据成熟的测量原理发展而来的。代表性测量是通过传感器上游和下游边缘的独特定位压力孔实现的。平均压差读数提供速度输出，以及静压和温度读数。
比较和优点
- 流量、温度和压力的连续代表性测量，适用于最大 8m 的烟囱直径，并输出到所选数据采集系统
- 具有代表性的流量测量技术，包含挑战仪器测量流量能力的内置零位和量程检查
- 自动入口清洁循环
- 可选探头反吹系统
- 不受烟气成分和变化的影响
- 更广的动态测量范围
高质量保证特性
ENVEA ProPitot™ 仪器可提供内置手动质量保证零点和量程检查，以满足法律要求， 包括 EN 14181, QAL 3, US EPA, 日常检查和 AST, US EPA 线性检查。
