SR41 是变面积式金属管浮子流量计，通过锥形测量管内浮子的高度读取流量，因此无需电源即可就地指示。可测量气体、液体与蒸汽，口径 15 至 150 mm，精度等级 1.5 级或 2.5 级，量程比 20:1；水流量范围 2.5 至 100000 L/h，空气流量范围 0.07 至 1000 立方米每小时。
需要远传信号时，可采用 24 VDC 或电池供电，输出 (4~20) mA 并支持 HART、Modbus、FF 或 Profibus 通信。接液材质可选 304、304L、316、316L、哈氏合金 C、钛材或 PTFE 衬里不锈钢，外壳防护等级 IP67，并具备浮子卡堵自诊断功能。
SR41 与差压式流量计有何不同？
它读取锥形管内浮子高度而非压差，因此无需电源即可就地指示，适合小口径管线的低流量测量。
精度如何？
提供 1.5 级与 2.5 级两种精度等级，全量程量程比为 20:1。
是否需要电源？
就地指示无需供电；需要远传时，24 VDC 或电池供电即可输出 (4~20) mA，并支持 HART、Modbus、FF 或 Profibus。
适用哪些口径与流量范围？
公称通径 15 至 150 mm，覆盖水 2.5 至 100000 L/h、空气 0.07 至 1000 立方米每小时。
