A water flow meter is a device which is used to measure the flow of liquid. It is also a useful device which facilitates in measuring the amount of liquid that flows through the pipes. These devices are generally installed in most of the industrial and domestic areas for the purpose of accurate measurement. It also helps to identify if there is leakage of water.
Basically, there are two board classifications for these devices which include the velocity meter and the displacement water meter. The compound meters are another variety which is a unique combination of both the displacement and the velocity meters. However, there are different variations of these two meters which include different features and prices.
In addition to the analog meters that are in use even today, there are digital meters which offer a higher level of precision and efficiency. These flow meters use various techniques to calculate and measure the flow of liquids. Some of the most commonly used digital devices include the ultrasonic and the magnetic devices which can precisely measure the flow of liquids.
All these meters function on the basis of certain mechanisms. Precise measurements are achieved by placing the meters near to the feed lines. The flow of liquids is measured accurately by these devices and the calculated results are sent to a database or displayed precisely on the meters.
The velocity flow meter basically measures the velocity and converts it into the volume of water. The data which is collected and received by these devices are converted into volume by using different mechanisms. There are several varieties of velocity meters which include the magnetic meters, ultrasonic, propeller, multi-jet and turbine meters. These meters are particularly ideal to measure the flow of large volume of water. Therefore it is used in huge industrial settings and plants.
Another notable variety of flow meter is the positive displacement meter which measures the flow of water by comparing it to the amount of liquid held in the chamber. The total number of times the chamber is filled and emptied helps to determine the flow of liquid. This device uses a piston mechanism to calculate and record the data. These devices are quite ideal to calculate low flow of liquids. Due to this specific attribute, these devices are found largely in hotels, homes, apartments and office buildings.
Water flow meters can be read in cubic feet or inches which vary according to its specifications. There are straight and circular registers which display the readings. Each of these registers includes a series of numbers which can be used to calculate the usage of water quite easily.
Today a huge spectrum of flow meters can be bought from various reputed online dealers and stores listed in the online portals. It is easy to find devices with a range of distinctive features such as corrosion-proof, strength and ability to withstand climatic changes. Most of these devices are also made available at affordable price rates.
