Flow sensors are used in a wide range of industrial applications from monitoring fuel consumption in a combustion engine to controlling a water pump’s output. SFM4100 AIR flow sensor is one of the newest additions to the field of flow sensors. It is a highly accurate, low cost and low power solution for measuring the flow rate of a variety of different fluids. The SFM4100 uses a patented hot wire technology gives it excellent accuracy and repeatability. It is capable of measuring flow rates ranging from a few milliliters per second to up to several hundred liters per second.

The SFM4100 has a wide range of applications. It is designed to be used in the air flow measurement of HVAC systems, air compressors, combustible engines, and water pumps. It can also be used in a wide variety of laboratory and industrial processes, for example, measuring the rate of fluid flow in fuel lines, or monitoring the output of pumps and nozzles. It is also suitable for measuring the flow rate of liquids and gases, providing accurate and repeatable measurements for a wide range of process control and work management applications.

The operating principle of the SFM4100 is straightforward and has been used for decades in a variety of flow sensing applications. The sensor utilizes an embedded hot wire that is heated to a certain temperature by an internal current generator. The hot wire’s resistance is then measured using a Wheatstone bridge circuit, which senses changes in the resistance that occurs as a result of changes in the flow rate. The raw resistance measurement is then digitally converted and processed to provide an accurate reading.

The signal conditioning and analog-to-digital converter of the SFM4100 ensures accurate and repeatable measurements, even in turbulent flow conditions. A programmable set point generates an output signal when a specific flow rate is reached. This is used as a control signal and can be used in a number of ways to ensure optimal performance from a system.

The SFM4100 AIR flow sensor is an excellent tool for measuring air flow in a variety of applications. It has a simple design and low power requirement, making it easy to accommodate in most systems. The accuracy and repeatability of the SFM4100 make it an ideal choice for any application requiring precise flow measurements.
