Note:
①The measuring range within 2-20SLM is available and regular measuring ranges such as 2、5、6、
10、12、15、20 SLM. Customized fee will be charged for other ranges.
②Standard-state: gas temperature is 0℃ and pressure is 101.325 kPa.
③The testing environment is room temperature and clear air.
④The pressure range of 1 MPa can be customized.
⑤The temperature compensation is for the tem. 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 10 SLM, the sensor zero output voltage is 1V and full scale
output voltage is 5V, and the actual output is 2.5V.
Then, the actual flow=10SLM * (2.5V - 1V)/(5V- 1V) = 3.75SLM

Cautions
1. Prohibit to use it in strong corrosive gas, toxic gas, explosive gas environment.
2. If measured gas medium contains dirt, the sensor’s lifespan will be shorten. 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.
