Product Specification
FS5001L series Mass Flow Sensors Description
The FS5001L mass flow sensors are manufactured using Siargo's proprietary MEMS flow sensor and package technology. the sensors are specially designed for low flow rate range applications from 0~200 sccm to 0~6000 cssm. the maximum flow rate for each model is manufactured via specially designed package as well as smart electronics so that the optimal sensitivity would be achieved.
The packaging enciosure is made of the chemically inert and thermally stable polybutylene terephthalate (PBT) material. The maximum over pressure rating can reach up to 5 bar (73psi) that is benefitted from Siargo's unique MEMS sensor chip structure, special packaging technology andthe rugged senor housing.
The FS5001L can be used in a wide range of applications including mass floe metering for process control, gas flow metrology, heating ventilation and air conditioning solutions as well as medical applications. The FS5001L requires a power supply of 8~24 Vdc and provides an analog output is linearized from 0.5 to 4.5 Vdc corresponding with flow rate from 0 to full scale. The digital output is I2C. The I2C protocol can be obtained from the manufacture.
The calibration is generally performed with air at 20°C and 101.325 kPa pressure rating. It can nonetheless be calibrated with other gases and conditions upon requests.

1 Denotes ±(2.0 %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 10 ms. It can be
programmed via I2C communication.
3 The maximum pressure drop is measured at flow rate 1000 sccm. For
lower range flow sensors, the pressure drop will be smaller. See
section 1.4 for details.
4 One DC power supply is necessary. The required minimum output
current is 50 mA. The sensor actually consumesless than that in
operation.
