Product Description

GFS131 Intensive care ventilator micro flow sensor

Description

GFS131 flow sensor uses the thermodynamic principle to detect flow rate of the gas medium in the flow channel, with good precision and repeatability. Temperature sensors are built-in and every one product is calibrated for temperature compensation. At the same time, it has linear analog voltage output, convenient to use.

Note:

1.The measuring range within 20-300SLM.

2.SLM means standard liter per minute. Standard-state: gas temperature is 0℃ and pressure is 101.325 kPa. The testing environment is room temperature and clear air.

3.The response time could be customized for 15-1000ms.

4.The 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 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.
