FS5001B series Mass Flow Sensors Description
FS5001B series mass flow sensors are designed for general purpose flow monitoring and control applications. The sensors directly measure mass flow in the designed channel with trace flow detection capability. The lowest flow it can detect is 20 μL/min. These sensors can readily be applied for manifold flow assembly, leak detection, HVAC control, clean room air flow or nitrogen flush monitoring and control, environmental equipments such as air sampler, analytical instrumentation such as GC spectrometer.
FS5001 can be configured to measure flow full scale from 100 sccm to 1000 sccm (1 SLPM). With a full spectrum of customizable adaptors, it can be plug-and-play in many applications.

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.
