High Accuracy Mass Flow Meters, High Quality Gas Flow Meter 0 ~ 25slpm
Description
The MF4001 mass flow sensors utilize Shelok's proprietary MEMS flow sensor and package technology to deliver exceptional performance. These sensors are specifically designed for applications requiring low flow rates, ranging from 030 sccm up to 01000 sccm. Each model is carefully manufactured with a specially designed package and smart electronics to achieve optimal sensitivity and accuracy.
The packaging enclosure of the sensors is constructed using chemically inert and thermally stable polycarbonate material. This ensures durability and reliability in various operating conditions. The sensors are capable of withstanding a maximum overpressure rating of 5 bar (73 psi), thanks to Shelok's unique MEMS sensor chip structure, specialized packaging technology, and the robust sensor housing.
In summary, the MF4001 mass flow sensors from Shelok combine advanced MEMS technology with innovative packaging solutions. They are specifically designed for low flow rate applications, offering precise and reliable measurements. The sensors' rugged construction and high overpressure rating make them suitable for demanding environments, ensuring long-term performance and durability.

Notes:
1. Denotes ±(1.5% Reading+0.5% Full Scale). To obtain accurate flow measurement, let the sensor warm up 1 minute at power up.
2. The response time is determined by ADC Sampling rate and data process algorithm. The default response time is 65 ms. It can be programmed via RS232 communication.
3. The maximum pressure drop is measured at flow rate 1000 sccm. For 500 sccm flow sensors, the pressure drop will be smaller. For 30, 100 and 200 sccm flow sensors, the flow pipe will be smaller, and the maximum pressure drop is <20 Pa at flow rate 200 sccm.
4. One DC power supply is necessary. The required minimum output current is 50mA. The sensor actually consumes less than that in operation.
5. Calibrations at other gases available upon request.

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.
