Introduction
S4000 series of air flow sensors (also called a flow meter) are specially designed for the measurement of medical gas flow and process control, which based on the MEMS flow sensor core technology , and applied to the kinds of clean and dry gas flow measurement with achievements of facility digitalization, intelligence and high safety compared to the traditional industry. S4000 series have the property of wide range of flow measurement which satisfy different flow measuring requirements with high sensitivity, high reliability and stability and low cost.
S4000 series promotes to development for more intelligence and energy saving.Application

1. Customizable range between 10SLM and 500SLM2. SLM: Standard liters per minute. Standard conditions: 0 ° C and 1 atmosphere3. In addition, the two-way airflow test can be customized, and the analog output is correspondingly changed. F(min)—F(max) corresponds to 1-5V output, and 0 flow corresponds to 3V;4. Includes temperature drift and linearity error5. 5V power supply voltage optionalLinear Output1. The unidirectional airflow mode: (calculation formula)Flow = [(VOUT -1 V) / 4 V] × full scale flowFor example: S4103V has a full-scale flow of 200 SLM. When the output voltage is read at 2.5V,the instantaneous flow rate is [(2.5V-1V) / 4V × 200 SLM] = 75 SLM
2. Two-way airflow mode: (calculation formula)Forward flow = [(VOUT -3 V)/2 V] × full scale flowReverse flow = [(3 V- VOUT)/2 V] × full scale flowShell SizeNote 1: The connector can be matched with a connecting line according to customer requirements.
