Product Features
High Measurement Accuracy
Linearity better than 0.5%, repeatability better than 0.2%, measurement accuracy within ±1%.
Wide Measurement Range
With different sensor models, capable of measuring flow in pipe diameters ranging from DN15 to DN6000mm.
High Protection Level
Fully potted waterproof design achieves an IP68 protection rating, allowing operation submerged up to 2 meters.
Compact Size
Dimensions: 170×180×56mm.
User-Friendly Operation
Parameters can be viewed using a magnetic wand on the primary display, or reset and displayed in Chinese through the secondary display.
Multiple Display Options
The primary display can show accumulated flow, instantaneous flow, and flow velocity. The secondary display features over 100 menu items in Chinese.
Long Transmission Distance
Communication between the primary and secondary displays (or computer) uses RS-485 bus, allowing for transmission distances over 1000 meters with standard cables. This setup enhances network convenience and reduces costs associated with specialized cables, while providing strong anti-interference capabilities.
