SVH 是面向液体、气体和蒸汽的高端涡街流量计,工艺包络更宽,可配分离式变送器。阻挡体在流体通过时交替泄出涡街;脱落频率与流速成正比。表体和阻挡体采用 CF8 或 CF8M 不锈钢,介质温度 -40 至 260℃,工作压力覆盖 -0.1 MPa 至法兰额定值。
宽供电电压 10.5 至 42 VDC 使 SVH 可与线路上其他仪表共用电源。4-20mA DC 两线制模拟输出和 HART 通信信号简化长距离布线。仪表提供一体式或分体式,分体式变送器可装在 2 英寸管上,适合工艺、化工、电力、水处理和油气行业。
SVH 可以测量哪些流体?
SVH 可测量液体、气体和蒸汽。应避免多相流和高粘度流体,这些工况会抑制涡街脱落。
SVH 与家族其他涡街流量计有什么区别?
SVH 是高精度、宽供电型号,介质温度范围更宽,可配分离式变送器。采用 CF8 或 CF8M 表体材质,DC 10.5 至 42V 宽供电便于集成。
SVH 支持的压力范围是多少?
SVH 介质压力覆盖 -0.1 MPa 至法兰额定值。宽包络覆盖真空和高压力工艺管线,标准电缆格兰头为 1 英寸 NPT 内螺纹。
SVH 如何输出信号和通信?
模拟输出为 4-20mA DC 两线制;HART 通信叠加在同一对线上,因此同一根电缆同时承载电源、输出和双向配置。分体式变送器可装在 2 英寸管上,用于远端安装传感器。
