FS15A

Flow Sensor is a very important sensor for industrial automation. In this article, we will talk about one of the most popular Flow Sensors – FS15A, its application field and working principle.

Application Field

FS15A Mass Flow Sensor can be widely used in HVAC, automotive, bioprocess, medical device, pharmaceutical, environmental, food and beverage industries. It can be used to detect, measure and monitor the flow rate of liquids and gases. The sensor can provide accurate and reliable feedback signal to the controlled device for effective process control.

Working Principle

The FS15A works on the principle of hot-film anemometry, which is based on the heat transfer between the hot film and the fluid flowing over it. The sensor measures the amount of heat transfer between the hot film and the fluid to determine the flow rate. The sensor has a hot-film element that is maintained at constant temperature by a precision electronics module. When the fluid flows through the sensor, the hot-film is cooled due to the heat transfer. The amount of cooling can be read by the controller and converted into the flow rate of the fluid.

The FS15A can measure both small and large flow rates from 0.25 to 2000in³/min. It is immune to shock and vibration and can operate in temperatures up to 125°C. It also has a maximum pressure rating of 500psi, making it suitable for high pressure applications. The sensing element is made of stainless steel to provide corrosion resistance and standard accuracy over its entire range.

Conclusion

The FS15A Mass Flow Sensor is a high performance and reliable flow sensing solution for many industrial applications. It is capable of measuring a wide range of flow rates, and is immune to shock and vibration. The stainless steel sensing element ensures standard accuracy over its entire range and makes it suitable for high pressure applications.
