Product Description:
YJJ AFD4020N33 Water Flow Sensor for Server Liquid-Cooling Circulation Real-Time-Monitoring
Features:
I. Detection Principle
Based on von Kármán vortex street principle, equipped with MEMS piezoelectric sensing chip; when fluid flows through the restrictor, vortices are generated, and the frequency of the vortices is proportional to the liquid flow rate. There are no moving parts for wear inside, and it is resistant to impure liquids and has strong stability.
II. Core Performance Parameters
Standard flow range: 2 - 16 L/min
Measurement accuracy: < ±3.0% FS
Repeatability error: ≤ 2.0% FS
Fluid allowable temperature: 0℃ - +90℃ (the medium cannot freeze or condense)
Working pressure specification: conventional working pressure 10 bar, instantaneous withstand pressure upper limit 16 bar
III. Electrical Parameters
Power supply voltage: DC 18 - 28 VDC
Current output configuration: NPN pulse signal output; optional 4 - 20mA, 1 - 5V, RS485 - Modbus, PNP output
Response speed: Fast vortex signal acquisition, suitable for instantaneous liquid flow monitoring
IV. Environmental and Physical Specifications
Sensor working environment temperature: -10℃ - +65℃
Contact liquid material: SUS304 stainless steel + PPS engineering plastic, resistant to common water-based chemicals
Pipe interface: G3/8 internal thread
Main body size: main body 40×40mm, total length 59.3mm, hexagonal locking 31mm
V. Core Product Advantages
Internal no moving parts, no mechanical wear, long service life, low maintenance volume in the future
Low pressure loss flow channel, very small pipeline pressure loss, good energy-saving effect
Resistant to minor impurities, not prone to clogging, suitable for industrial water circulation, chemical dosing conditions
Rich output methods, can be connected to PLC, flow meter upper computer software
Optional integrated needle valve, directly integrates flow regulating valve, eliminates external valve accessories
