1.  When  magnetic material is close with  the sensor,its characteristics may vary.
2.  In order to avoid particle debris, the sensor must beinstalled after a filter.
3. The flow sensor installation  has to avoid strong vibration and shaking of the  environment, so as not to affect the sensor's measurement accuracy.
