世伟洛克®变截面流量计使用锥形管和浮子来测量液体和气体的流速。当流体流量增加时,浮子上升,当流量减少时,重力将其下拉。这些流量计易于安装和读数,设计上没有易损件,尽可能地减少了维护需求。10 比 1 的调节比—使最低测量值仅为满量程读数的十分之一—提供了测量精度。这些流量计有美制和公制两种刻度,适用于各种应用和位置。

所有世伟洛克变截面流量计都在工厂内按照指定的介质、流量范围和精度等级进行了校准,气体型使用清洁干燥的空气,液体型则使用水。它们还可根据用户的具体应用进行校准。

M 系列变截面流量计(M1、M2、M4 和 M4H 型)

世伟洛克® M 系列流量计采用金属测量管,适用于高温或高压的挑战性条件。由于不可能使用金属测量管直接读数,这些型号配有机械或电子显示屏,以确保监测的清晰准确。
