Gas and Liquid Flow Sensor Module

Features

Description

The FS1012 MEMS mass flow sensor module measures the flow

rate using the thermo-transfer (calorimetric) principle. The FS1012

is capable of measuring a gas or liquid medium.

Gas or liquid mediums

Robust “solid” isolation technology

Resistant to surface contamination

No cavity to cause clogging

The FS1012 offers key advantages over resistor-based flow

solutions. The sensor utilizes thermopile sensing, which provides

an excellent signal-to-noise ratio. The sensor comprises a “solid”

thermal isolation technology and silicon-carbide coating to protect

it from abrasive wear and provides robustness and long-term

reliability. In comparison, other sensors typically contain a fragile

membrane above an etched cavity for the thermal isolation base.

Resistant to vibration and pressure shock

Low power application

Sensitive at low flow rates and differential pressure levels

Fast response: 2ms

Millivolt output

The FS1012 features the sensor fully assembled and wire-bonded

out to a 6-pin header.

Supply voltage: 3V to 5V

Module operating temperature range: 0°C to +85°C
