Water flow meters are basically the tools which are used to measure the consumption of water. It measures the total amount of water used by any source through different methods. These meters are designated in specific points to identify leakages of water.

Although modern technology has led to the invention of various types of flow meters, two of the most commonly used meters include the positive displacement meter and the velocity meter. There are devices which combine the features of both these meters are known as the compound meters. These devices particularly use a valve mechanism which directs the flow of water into both these meters so that it is easy to obtain readings from both the devices.

Types of Flow Meters:

Positive Displacement Meters: These meters include a small chamber which holds a measured volume of water. The flow of water is measured and compared to the previously held volume of liquid. The flow rate of the liquid is calculated by measuring the number of times the chamber is filled and emptied. These instruments are most commonly found in homes and apartments as it is ideal for measuring low flow rate.

Velocity Meters: These devices measure the velocity of the flow of liquid and translate it into the volume of the flow of water. Different mechanisms are used by these machines to measure the velocity and translate the data. Some of the most popularly used meters include the ultrasonic, venturi, multi-jet, magnetic, orifice, propeller meters and so forth. All these devices measure the velocity of the flow. It is quite ideal for high flow areas and therefore it is used in businesses which utilize large flow of liquids.

In addition to the analog meters, digital water flow meters are gaining immense popularity in the current scenario. Digital devices are used in scientific and commercial fields as it is quite efficient and accurate. The digital flow meters utilize different techniques and mechanisms to calculate the flow of liquids. The magnetic flow devices and the ultrasonic devices are the two common types of digital devices used widely. It is quite easy to interpret the data on digital display systems. It is also possible to link the data to the valve of the pipe systems and adjust the flow accordingly. The operators can also retrieve the information from the digital system easily.

Water flow meter display systems are available in two different varieties which include the circular and straight. These displays can be found on the face of the meters. Most of the conventional meters include circular registers which are quite complex to calculate. It uses a series of dials and therefore the usage of water is calculated with the help of a string of numbers.

These devices include a large number of beneficial features apart from the advantage of accuracy in measurements. It facilitates in increasing the power of water supply with a reduced power supply. Most of these devices are designed to withstand the vagaries of nature.
