NOTE:

1.The measuring range within 50-300SLM is available and regular measuring ranges such as 50,
100,150,200,300SLM.Customized fee will be charged for other ranges.

2.SLM means standard liter per minute. Standard-state: gas temperature is 20℃ and pressure is 101.325 kPa.

3.Customization of response time between 10ms and 1000ms. This response time refers to the electronic response time by the flow sensor for any mass flow change from 10% to 90%. which may be affected by the aerodynamic interface.

4.The temperature compensation is for the temperature range of 0-50℃ and the compensation performance can’t be ensured beyond the temperature range.

Calculation for Airflow

Actual flow=full scale * (sensor actual output voltage-zero output voltage) / (full scale output voltage-zero output voltage)
For example: the sensor full scale is 200 SLM, the sensor zero output voltage is 0.5V and full scale
output voltage is 4.5V, and the actual output is 3.5V.
Then the actual flow=200 SLM * (3.5V – 0.5V)/(4.5V- 0.5V) = 150SLM

Cautions

1. The air inlet and air outlet of the sensor need to be equipped with long straight pipe to ensure the product’s performance. It is recommended to leave a straight pipe for the inlet with 10 times longer than the pipe diameter while the outlet will be 5 times longer.

2. If measured gas medium contains dirt, the sensor’s lifespan will be shortened. We suggest users equip the sensor flow inlet with 5 micrometer precise filter.

3. The sensitivity of the product will reduce or be damaged if it contacts to water.

4. The wrong connecting of power supply will damage the internal circuit.
