Blade core technology
Using non-magnetic stainless steel, one-time processing and molding, for micro-signal interference and adjusting the precision of the friction coefficient of the blade surface, effectively increase and reduce the blade speed and adjust the measurement coefficient
CNC integrated precision machining
Impact resistance - The blades of the turbine are processed in one piece without contact, which has strong impact resistance, more balance, real flow performance, and better dynamic balance of operation. At low flow rates, no idling value is generated, which is your precise check.
One-piece processing and molding
Streamlined guide bearing
Stainless steel bearings are selected, with stronger impact resistance, effectively reducing fluid pressure loss and avoiding measurement errors
Blades without solder joints
High-precision machining, the blade is arc-shaped
Universal Welded Blade|Ordinary Probe Steel Material Guide Bearing
Blade solder joints are prone to embrittlement and fracture
The blade is flat, and the smoothness cannot measure the small flow on the side.
Poor impact resistance, easy to wear, small and too poor shunt, causing interference to measurement
Computing Processor Design:

Adopt multi-layer module function board design, any damage to any function board can be replaced independently
Adopt communication socket connection design, strong and stable signal connection
