科寶流量計介質溫度0-80℃

科寶流量計中緊湊型的KOBOLD DVZ型渦街流量計用于測量和監(jiān)測管道中的中小流量的低粘度，類似水的液體。 該設備使用渦流原理工作，使其幾乎免維護。

這涉及在流道中安裝鋒利的物體（渦流發(fā)生器）。 在物體后面形成渦旋，其頻率與液體的流速成正比。 通過測量渦旋頻率可以非常精確地確定流量。 這在整個測量范圍內實現(xiàn)了非常高的線性度。

The compact KOBOLD Vortex flowmeter Model DVZ is used
for measuring and monitoring smaller and medium-sized flow
of low viscosity, water-like liquids in pipes. The device works
using the vortex principle, making it virtually maintenancefree.
This involves the installation of a sharp-edged object (the
vortex generator) in the flow duct. Vortices are created behind
the object whose frequency is proportional to the velocity of
flow of the liquid. The flow volume can be determined with
a very great degree of accuracy by measuring the vortex
frequency. This achieves a very high linearity over the whole
measuring range.
