25slpm
Description
The MF4001 sensors from YUNYI utilize advanced MEMS for superior
performance. Tailor-made for low flow rates between 30 sccm and
1000 sccm, these devices combine a custom housing with smart
electronics to ensure high sensitivity and precision. Made of
sturdy polycarbonate, they are chemically resistant and maintain
functionality across varying temperatures. With a robust build,
they can handle up to 5 bar overpressure, ensuring reliability in
harsh environments.

Notes:
- Accuracy is denoted by ±(1.5% of Reading + 0.5% of Full Scale). For
precise flow measurements, allow the sensor to warm up for 1 minute
after power-up.
- The sensor's response time is influenced by the ADC Sampling rate
and data processing algorithm. It has a default response time of 65
milliseconds, which can be adjusted through RS232 communication.
- The maximum pressure drop is observed at a flow rate of 1000 sccm.
For sensors with 500 sccm capacity, the pressure drop will be less.
In the case of 30, 100, and 200 sccm flow sensors, the flow pipe is
narrower, resulting in a maximum pressure drop of less than 20 Pa
at a flow rate of 200 sccm.
- A DC power supply is required, with a minimum output current of
50mA. However, the actual operational consumption of the sensor is
lower than this value.
- Calibrations for other gases are available upon request, offering
flexibility for various applications.

Applications
The versatile MF4001 mass flow sensor finds applications in a wide
range of industries, including instrumentation such as GC mass
spectrometry, leak detection, process control, gas flow metrology,
and medical applications. It offers flexibility and reliability for
various measurement needs.
The MF4001 operates on a power supply of 8~24V DC and features both
analog and digital user interfaces. The analog output provides a
linearized signal ranging from 0.5 to 4.5V DC, corresponding to the
flow rate from 0 to full scale. The digital output is available
through RS232 or I2C protocols, allowing for convenient data
transmission and integration with other systems. Detailed
communication protocols for RS232 and I2C can be found in the
provided manual.
The sensor's calibration is typically performed using nitrogen gas
at a standard temperature of 20℃ and pressure of 101.325kPa.
However, upon request, the MF4001 can be calibrated with other
gases and under different conditions to meet specific application
requirements. This customization ensures accurate measurements in
diverse operating environments.
