Please note that this product cannot sense very small air bubbles or water drops. Refer to the figure 1 and 2. 3) Sensing is affected by dirt or residues adhered to the inner wall of the tube. Please maintain the tube regularly. 4) When using a tube out of specifications or it doesn't have a smooth surface, please test sensing on the actual machine before use. 5) Actual response time may differ from specification (typical example using applicable tube) due to dimension, light transmission or surface state of test tube in use. 6) Liquid being detected should also be kept within the rated ambient temperature range. 7) Confirm that the power supply voltage at the end of cable is more than 4.5 V when using an extension of over 20 m 65.167 ft.
