Usage and Technology of Paddle Wheel Flow Sensor

Titile

The paddlewheel flow sensor is vital in gauging the flow of a known volume of a fluid. They work when you insert them in the flow channel. That has earned them the name inline flow meters or insertion flow meters. These designs are cheap, easy to install, and highly accurate.

If you want your paddlewheel flow sensor to work well, ensure that you use clean fluids. Particles can inhibit the rotation of the paddle.

Components of a Paddlewheel Flow Sensor

This type of sensor has three components: the pipe fitting, paddlewheel sensor, and flow display. Let's look into a brief description of the element.

Pipe Fitting

This component is the part that attaches the sensor to the fluid pipe. It exists in several flow ranges to fit different applications.

The Sensor

You insert this component into the pipe fitting. It has a paddlewheel with a fixed electric sensor and a magnet. 50% of the paddle extends into the stream. The fluid in the stream spins the paddlewheel. As this happens, the magnets rotate around the sensor. The process creates electrical pulses that are equivalent to the flow rate of the liquid.

Flow Display

This component is also known as the controller. It collects the pulse signals and converts them into a readable format. These processed signals help in the regulation of valves and pumps.

The Technology of Paddlewheel Flow Sensor

We have lightly touched on the technology of the paddlewheel flow sensor when describing the parts. In this part, we will talk more about how the sensor works.

The paddlewheel creates signals when the blades spin past the sensor: the voltage signal and frequency are directly related to the flow rate. The flow sensor needs to have some straight pipes before and after the sensor.

The display is useful in collecting the pulse signals and converting them into total flow value.

The processed signals are essential in so many aspects. For instance, you can use it to send alerts to external, send alarms, switch a pump on and off, or even open and close valves.

When to Use the Paddlewheel Flow Sensor

This type of sensor has a wide range of uses. It is popular since it is affordable and accurate. Also, it is versatile and easy to read. The only time you can't use the sensor is if you are dealing with sticky fluid or one contaminated with particles. Since it is an insertion type, the particles can block the rotating paddles.

Its application is simple since you use it on an existing pipe. Ensure you fix the sensor into the line well. Any mistakes can lead to errors in readings.

Conclusion

Paddle wheel flow sensors are easy to use. Paddle Wheel flow-meter carries the exact measure of preset fluid quantities in managing systems, control of chemical metering pump output, and alerting users to flow rate increases or decreases outside a programmed range. Their working principle is also easy. Thus, they are a popular choice in many industries.
