Mass Gas Flow Sensor alternate to Honeywell sensor AWM3300V, AWM3000 Series.
Description
S3000 series of micro-gas flow sensors are fabricate with MEMS flow chips and applied to measure kinds of clean and dry micro-gas flow and process control with special package technology and satisfy with different flow range measurement with same diameter. It has advantage of high sensitivity and reliability and low cost and very wide applications.
Feature
■Flow range: 0- 3000 (50, 100, 1000, 2000, 2500, 3000)sccm
■High precision ( ±1.5 %FS accuracy)
■Linear output and no temperature compensation required
■Maintain long-term stability with minimal zero drift
■Solid-state sensing core (no surface void or fragile membrane), anti-blocking and pressure shock
■Analog output ( 1 - 5 V) ( I2C or RS485 are also available )
■Fast response time ( 1 ms response time)
■Can adapt to relatively humid gas measurement

Linear Output
Flow = [(VOUT -1 V) / 4 V] × full scale flow
For example: S3000 has a full-scale flow of 1000 sccm. When the output voltage is read at 2.5V, the
instantaneous flow rate is
[(2.5V-1V)/4V×1000 sccm] =375sccm
