Product catalog summary

Flow Sensor Specifications

Usage: The flow sensor is designed to detect liquid flow and measure flow rates, commonly used in products like smart toilets and drinking fountains.

Parameters:

Model: AFM-3
Rated Voltage: 5 VDC
Rated Flow: 300cc to 2000cc per minute
Max Flow Rate: 3500cc per minute
Storage Temperature: -20℃ to 85℃
Operating Liquid Temperature: 0℃ to 80℃ (except when frozen)
Operating Temperature Range: -20℃ to 80℃
Operating Humidity Range: 45% to 95% RH
Weight: 20g

Features:

The sensor operates based on liquid rate and frequency characteristics with a tolerance of ±8%. The frequency response at various flow rates is as follows:

500 cc/Min: 64 Hz/sec
1000 cc/Min: 130 Hz/sec
1500 cc/Min: 198 Hz/sec
2000 cc/Min: 265 Hz/sec
2500 cc/Min: 333 Hz/sec
3000 cc/Min: 400 Hz/sec
3500 cc/Min: 467 Hz/sec

Testing Parameters:

Life Test: After 1000 hours under a loading pressure of 1.0 kgf.cm², the frequency value should remain within 3% of the initial value.
Pressure Test: The sensor should not leak within 5 minutes under a pressure of 3.0 kgf.cm².
