RS485 Output Mass Digital Air, Gas Flow Sensor

Description RS485 Output Mass Digital Air, Gas Flow Sensor

The MF4001 mass flow sensors are manufactured using Shelok proprietary MEMS flow sensor and package technology. The sensor are specially designed for low flow rate range applications from 0~30 sccm up to 0~1000 sccm. The maximum flow rate for each model is manufactured via specially designed package as well as smart electonics so that the optimal sensitivity would be achieved.


The packaging enclosure is made of the chmically inert and thermally stable polycarbonate material. The maximum over pressure rating is 5 bar (73 psi) that is benefitted from Shelok unique MEMS Sensor chip structure, special packaging technology and the rugged sensor housing.

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 4-20ma Output Mass Digital Air, Gas Flow Meter

The MF4001 can be used in a wide range of applications inculding instrumentation(e.g. GC mass spectrometry), leak detection, process control, gas flow metrology as well as medical applications. The MF4001 requires a power supply of 8~24V DC and provides an analog and/or digital user interface. The analog output is linearized from 0.5 to 4.5V DC corresponding with flow rate from 0 to full scale. The digital output is via RS232/12C. The communication protocol of the RS232 and I2C can be found in this manual.

The calibration is generally performed with nitrogen at 20℃ and 101.325kPa pressure rating. It can nonetheless be calibrated with other gases and conditions upon requests.
