We will discover what is an afm3000 mass flow sensor, how it functions, and a great device from reputable sensor maker Saftty in this article.

What Is An AFM3000 Mass Flow Sensor?

The afm3000 flow sensor has a digital I2C interface and runs on a 5 Volt supply source. Internal linearization and temperature compensation are applied to the measurement findings. Our sensor technology, which combines a heat sensor chip and a high-performance integrated 24-bit AD acquisition CMOS microprocessor, provides the foundation for the exceptional performance of our afm3000 mass flow sensor. A thermal sensor element that measures the gas flow rate ensures extremely quick signal processing and bidirectional monitoring with best-in-class accuracy.

The Purpose Of An AFM3000 Mass Flow Sensor And Its Operation

An afm3000 mass flow sensor is a tool that gauges how much material passes through it during a predetermined time frame. To keep track of levels of throughput, reactivity, and contamination in industrial settings, it is frequently utilized. It is also employed in production to gauge the volume of liquid or gas flowing through the apparatus.

Thermal mass flowmeters, differential pressure mass flowmeters, and Coriolis mass flowmeters are the three primary categories of mass flowmeters, respectively.

Different mass flow meters operate according to different principles. Here, the basic operation of two afm3000 flow sensors is described.

1.Guin’s law is the foundation for how thermal mass flow meters operate. In other words, the gas in the pipeline being monitored is heated outside, the heat energy flows with the gas, and the heat change caused by the gas’s flow is detected. Two reference-grade RTDs, a velocity sensor, and a temperature sensor that gauges changes in gas temperature typically make up the sensor within a thermal mass flow meter. The speed sensor is heated when the two thermal resistors are inserted into the pipeline with the gas that will be measured, and the other temperature sensor is then utilized to gauge the temperature of the gas.

2.The differential pressure mass flowmeter operates according to Poiseuille’s law. The volume flow of the gas is estimated and then converted to the mass flow under typical operating conditions by measuring the pressure differential before and after the gas flows through a certain segment of the pipeline, that is, the pressure loss. This working concept is based on the assumptions that the gas under test must be in laminar flow motion, travel through an invisible stack of laminar flow sheets, and maintain laminar flow motion between the stack of laminar flow sheets. The flow rate of the gas in this segment may therefore be estimated as long as the difference in pressure between the two ends of the laminar flow sheet is known.

The differential pressure mass flowmeter, which measures the pressure difference, is more precise than the thermal mass flowmeter, which measures the temperature difference.


A precise tool that detects the volume of material flowing through it is an afm3000 mass flow sensor. Only a reputable provider can provide a high-quality mass flow sensor, and Saftty is that supplier.
