2. Main functions and features
-
Dual parameter monitoringNot only can it measure flow velocity, but it can also monitor medium temperature simultaneously without the need for additional temperature sensors.
-
intuitive displayThere is a 4-digit LED display screen on the top of the device, which can directly read numerical values.redThe indicator light can quickly indicate whether the flow is within the set range (green indicates normal, red indicates abnormal).
-
Flexible installationThe process joint can rotate, making it easy to adjust the angle in a small space and achieve optimal alignment.
-
high adaptabilityOptimized for water, oil, and air, suitable for various industrial scenarios.

3. Installation and usage suggestions
-
Installation locationSuggest installing it in the pipelinelow pointorVertical segmentEnsure that the pipeline is filled with medium (full pipe state) to avoid interference from bubbles.
-
Requirements for straight pipe sectionsTo ensure measurement accuracy, there should be sufficient straight pipe sections upstream of the sensor (usually recommended for 5D in the front and 3D in the back, where D is the pipe diameter) to stabilize the flow field.
-
Attention to wiringThe device has reverse phase protection function, but it is still necessary to confirm the correct polarity of the power supply when wiring to avoid damaging the device due to reverse connection.
4. Common troubleshooting
-
No output/inaccurate dataCheck if the power cord connection is secure and confirm that the operating voltage is within the range of 18-30V DC.
-
The signal fluctuates greatlyCheck if the sensor is subjected to strong electromagnetic interference and ensure that the shielded wire is reliably grounded.
-
Display abnormalityIf all LEDs flash red, it usually indicates installation error or parameter setting failure, and installation conditions need to be checked or parameter settings need to be reset.
