S201 G1/2 Hall Water Flow Sensor DC 5V Liquid Flow Meter for Water Purifier Heater Vending Machine Application
S201 G1/2 Hall Water Flow Sensor DC 5V Liquid Flow Meter for Water Purifier Heater Vending Machine Application1.NOTE:
1.To prevent particles or debris from entering the sensor, a filter screen must be installed at the water inlet.
2.The flow sensor should be installed indoors or within enclosed equipment. Avoid exposure to outdoor environments, high humidity, extreme temperatures, or harsh conditions. For accurate measurement, ensure the installation location is free from vibration or shaking.
3.Keep the sensor away from magnetic materials or any devices that generate magnetic fields, as these can interfere with its performance.

5.FAQs
Q1: Can I install this sensor outdoors?
A1: No. The sensor should be installed indoors or in a dry, controlled environment. Exposure to humidity, high temperatures, or vibration can impact its accuracy and performance.
Q2: Can I replace my old flow sensor directly with this model?
A2: If you haven’t used this specific structural model before, we recommend testing for compatibility first or contacting us for guidance.
Q3: Do I need a filter with this sensor?
A3: Yes. A filter is required at the water inlet to prevent debris from entering and damaging the sensor.
