Flow sensors

A flow meter is a measuring device that measures the quantities of liquids and gases. Such meters are useful in home applications, also when making various own DIY projects, and find industrial use. Some flow sensors measure the amount of gas or liquid flowing over a certain period of time - this can be 1 L / min or another value. In turn, other flow meters are equipped with functions that allow counting the amount of gas or liquid that has flowed through the test organ of the sensor. Then, on the analog counter or LCD display, you will find information about the air flow in a given amount of liquid. In this category you will find the best gas and liquid flow meters. You can use them for various purposes. In our store's offer you will also find sensors for measuring the pH of the liquid (neutral, acidic, alkaline), as well as checking to what extent the liquid is clean.

How does an electromechanical liquid flow sensor work?

The testing organ of the flow sensor is a small turbine with blades and a Hall sensor. As liquid flows through the sensor, the pressure of the liquid (e.g. water) exerts pressure on the turbine blades, causing them to rotate. A stationary magnet is mounted on the turbine shaft. As the turbine rotates, the magnet on the shaft passes the stationary sensor element, which results in the creation of an alternating magnetic field, which creates a small voltage. The voltage generated in the Hall sensor is converted into a pulse that is counted by the measuring system, which allows obtaining information about the amount of liquid flowing through the sensor via the measurement algorithm. The same operating principle is used in hydroelectric power plants when checking the operating parameters of water turbines before they are coupled with power generators and connected to the power grid.

Liquid and gas flow sensors - ideal for cooperation with embedded systems

The Botland store offer includes a number of modules and attachments that can be easily connected to microcontrollers, creating an extensive measurement system. Among them, there are also sensors for measuring the flow of liquids and gases, such as the YF-G1 sensor, which allows measuring the amount of liquid in the range from 2 to 100 l/min. The measurement method uses the Hall effect. The sensor connector has three wires - red for connecting the auxiliary power supply voltage in the range from 5V to 24V, black wire for power supply ground and yellow wire responsible for transmitting measurement pulses. The sensor can work with, among others: with the Arduino platform.

Flow sensors - Botland - Shop for robotics

This category includes reliable and precise gas and liquid flow sensors, e.g. water, from manufacturers such as DFRobot, Seeedstudio, SparkFun and others. We offer, among others: analog flow sensors operating in various measurement ranges. The sensors placed on the board have clearly marked pins. In practice, this means easy and intuitive connection, e.g. to Arduino or other microcontrollers. Individual flow meters differ from each other, among others: thread diameter, permissible pressure, humidity and other parameters.

Flow sensors - FAQ

▷ Liquid flow sensor - can they be connected to SUPLA?

Yes, the liquid flow sensor can be connected to SUPLA . You can find ready-made guides online that explain step by step how to connect a flow sensor to SUPLA.

▷ Liquid flow sensor - which one to choose?

When choosing a meter intended for measuring liquid flow, special attention should be paid to the operating range, which may be expressed, for example, in liters for each minute of sensor operation. Other important factors are: supply voltage range, operating temperature range, mounting method, maximum liquid flow pressure and permissible humidity. Additionally, when choosing a sensor, you should take into account the sensor's size, shape, and mounting method. Selected models also enable measurement of the PH of liquids and even measurement of gases.
