A digital water flow regulator plays an important role in automatic systems today. These pressure regulator are easily set to larger electronic since are small low cost and reliable device. Today you can find various types of regulators in the market to use for different purposes. With the advance level of technology regulator are also develope in their functioning and size. From the early size of cm units, the size of the pressure controllers has shrunk to the scale of nm. Commonly regulators are use to solving many challenge of electronic and electrical engineering that include finding the intensity of ambient light specifying the temperature in the furnace system. Calculating the humidity of the surroundings, and more. The electronic pressure regulator provides an amazing solution to measure the flow rate of liquids.
An electric air pressure regulator is generally use in huge industrial plants and commercial as well as residential building that require a large amount of water supply through the system. The public water supply system is use to fulfill this requirement. To check the amount of water that is supplied and used, the rate of flow of water has to be measured and a digital water flow regulator is used for this purpose.
The digital pressure regulators are installevat the water source or pipe to measure the rate of flow of water and calculate the amount of water and how much water flow through the pipe. The rate of water flow is generally measure as liters per hour or cubic meters.
Working Principle of the electronic pneumatic regulator:
The water flow regulator consists of a plastic valve from which water can pass through the system. The water flow sensor consists of a copper body, a water rotor, and a hall-effect sensor. When water flows through the rotor, the rotor rolls, and its speed changes with different rates of flow. And the hall-effect sensor outputs the corresponding pulse signal. A water rotor that is attache to a hall effect regulator is present in the sense and measure the water flow rate.
When water flows through the valve it rotate the rotor. And the change can be follow by the speed of the motor. Direct mass flow measurement is an important development across. Industries as it eliminates inaccuracies caused by the physical properties of the fluid. Not least being the difference between mass flow and volumetric flow. Mass is not affect by change temperature and pressure. This change is estimate as output as a pulse electric signal by the hall effect regulator. Therefore the rate of flow of water can be measure instantly.
The main working principle behind the working of this digital water flow regulator is the Hall effect. According to this principle a voltage difference is generate. In the conductor due to the rotation of the rotor in the system. This generate voltage difference is cross to the electric current.
When the move fan is rotate due to the flow of water it rotates the rotor which induces the voltage. This induce voltage is measure by the hall effect of the electronic air regulator and display on the LCD screen.
The electric air pressure regulator can be used with hot waters, cold waters, warm waters, clean water, and also dirty water. Measurement of water flow is accomplish with flow meter hardware which measures and total water flow. All flow meters include a flow sensor. Some sensors have a paddle wheel or impeller inside. The flow meter that sends electrical pulses as it measures water flow. These pressure regulators are available in different diameters, with various flow rate ranges.
Generally, the digital water flow regulator can be easily interfaced with different microcontrollers and is placed at the water source inlet or at the opening of the pipe.
