Burkert S030-555346 Fitting inline DN15 SST/paddle wheel PD
Core functions and features
Measurement principle
Paddle wheel (impeller) mechanical sensor, the fluid drives the paddle wheel to rotate, and the speed is proportional to the flow rate
Non-contact magnetic induction detection (Hall effect or magnetic resistance principle), no mechanical wear
Signal output
Pulse signal (frequency output):
Typical output: square wave pulse (such as 1~1000Hz), the corresponding number of pulses per liter is adjustable (K factor calibration)
Compatible with counting devices such as PLC, flow integrators
Optional analog output (need to confirm the model suffix): 4~20mA (corresponding to the flow range)
Mechanical parameters
Installation method: online threaded connection (G½", NPT½", etc.) or flange type (need to be confirmed)
Pressure rating: PN16 (standard), higher pressure needs to be customized
Medium temperature: -10°C to +100°C (standard, high temperature optional)
Electrical parameters
Supply voltage: 5~24V DC (pulse output type)
Load capacity: ≤20mA (NPN/PNP output)
Protection level: IP65 (sensor head)
Technical parameter table
Project parameters
Measuring range: Water: 0.3~6 m/s (typical), depending on the viscosity of the medium
Accuracy: ±1% reading (after calibration, water medium)
Repeatability: ±0.5%
Wetted parts: Paddle wheel: 316L stainless steel / Shaft: Ceramic / Seal: FKM or EPDM (optional)
Media compatibility: Water, low viscosity oil, coolant, etc. (not suitable for high viscosity or solid particle containing media)
Pressure loss: <0.1 bar (at maximum flow)
Product features
Compact structure: DN15 small diameter design, suitable for space-constrained pipeline installation
Low flow sensitivity: Optimized paddle wheel design, can detect small flow (minimum 0.3 m/s)
Passive type optional: no power supply required, only mechanical pulse output (magnetic induction)
Typical applications
Industrial circulating water: cooling system flow monitoring
Lubrication system: oil flow detection
Laboratory equipment: small pipeline liquid metering
OEM integration: as a low-cost flow detection module
Selection notes
Media requirements: suitable for clean liquids, if containing particles, a pre-filter is required
Flow direction mark: during installation, ensure that the arrow direction is consistent with the fluid flow direction
