The voltage difference depends on the properties of the conductor(metal of which conductor is made). Flow meter is actually a valve. It seems to me that what you need for that is a sound pressure level sensor that the Arduino can read. - sekdiy/FlowMeter I'm going to have to read up on interrupts. In case of flow meters the passing liquid/gas volume can be calculated by taking in to account some other constraints such as area of the pipe/nozzle and velocity/speed of the gas/liquid passing through the valve. You can use it to count flow and volume of liquids and gases (although the documentation … In the above circuit i attached the pulse output pin of flow sensor to arduino digital pin 3. That’s why can find G1/2 or G3/4 in the sensor name. Flow Sensor terdiri dari tiga pin saja. Flow sensor helps you to calculate the flow rate and volume of liquid that has passed through the pipe. Then two volatile variables ‘pulsecount‘ and ‘i‘ are used to count pulses and check led status. We have a fan in flow meter which rotates when water passes through it. At the end i declared the led pin as output in setup function and i also opened the arduino serial channel at 9600 baud rate. Water and wastewater treatment facilities have the critical job of producing a safe supply of high quality drinking water. Choose Your Platform. The Water Flow Sensor for Flow Rate & Volume Measurement using Arduino works on the principle of the Hall effect. The flow meter design and development involves hardware and software, let’s see how it is developed. For more detail please check the Thread standard. Their operational processes are complex and involve a wide range of flow measurement tasks. Flow rate is then printed on the arduino serial monitor. Magnet is perpendicular to the conductor and current flow across the voltage source is some what halted or reduced due to voltage difference induction across the conductor. You can attach a character 16×2 lcd to the system on which the current flow rate is displayed. Furthermore, we have added some tutorials like how to build your own weather station with Arduino or how to use flow sensors on Raspberry Pi and many more. For this purpose using interrupts is a best choice. Where 7.5 represents a constant value which is calculated by the manufacture for particular flow sensor 1 represents water in liters and 60 represent seconds or 1 minute. These applications demand the highest flow meter … Here, the Hall effect is utilized in the flow meter using a small fan/propeller-shaped rotor, which is placed in the path of the liquid flowing. Flow meters works on the principle of hall effect. By the way, both YF-S402 and YF-S201 are commonly used in Arduino and Raspberry Pi water flow sensor projects.

You can check all the Seeed water flow sensor thread diameter in the following table: For the water flow sensor the most important parameters are: You can find all the information in the table above, just make sure you choose the right water flow sensor with the right parameter. You can still use the BSP water flow sensor with your NPT pipe, Just need to do some simple conversions. ​ Where 1000 mL= 1 liter. This voltage difference can be measured and calibrated across a scale. The Arduino controlled the duty cycle of a 12V DC fan in order to vary the velocity flowing through the venturi meter. y = 1.1409x^2 + 44.958x, in our arduino code. If water can be monitored so it can also be controlled hence some flow meters have special circuits with actuators through which we can control the water flow. By using a flow sensor with a microcontroller like Arduino, we can calculate the flow rate, and check the volume of liquid that has passed through a pipe, and control it as required. The pulse signal is a simple square wave so its quite easy to log and convert into liters per minute using the following formula. YF-S201 water flow sensor. You need to open the arduino serial monitor at 9600 bps in order see the flow rate. Note: Frequency of this flow meter is given by 7.5 * Quantity(L/m). FREE Shipping on your first order shipped by Amazon. The water flow sensor consists of a plastic valve body, a water rotor and a hall-effect sensor.
