With the constant growth of science and technology different types of measuring instruments have been invented and one of these technologies is the meters to measure the flow of water. They help to measure the flow rate of certain types of liquids and gases. These instruments are available in two different types such as oil or water flow meters; they also vary in the measurement capabilities and how much fluid passes through them during a specific time spam. Low flow meters are those which measure the flow of liquid which is flowing at a low rate. They are used both for domestic and industrial purposes.

Low flow meters as the name suggests measure very low amounts of fluid such as water which can be beneficial to know the quantity of the water in homes, industries and at public places which helps in planning to conserve the water for future use. Two types of meters can be used when measuring the flow of the water; these are the positive displacement meter and the velocity meters. In the first type of meter the mechanism which is used to measure the flow is compare with the previous flow of the water. Number of times that chamber is filled is the quantity of water. In second type of meters the volume of water is measured by measuring the velocity. The main features of a low flow meter are:

It helps in measuring low amounts of the liquid which makes it good for home use and small industry use.

They are far less costly as compared to other meters.

They are very easy to access, clean, assemble and disassemble in the field, which makes it user friendly.

They are relatively small in size which helps to reduce the relative velocity.

Though they are small in size so it is very easy to maintain them.
Low flow meters are very useful in homes, apartments and offices as they are considered to be more accurate, along with that it is very easy to install them and having all the attractive features. Such water meters are also becoming popular as they helps to prevent unnecessary waste of water. They are usually able to measure the low rate of flow of water which makes it more useful in homes and small industries.

Measuring an engine oil flow rate is one of the most difficult flow measurements. Low flow meters are helpful in these applications as well. Automotive engineer uses these meters to measure less quantity and that too with a very slow rate of flow under certain operative conditions. So low flow meters are actually very helpful in almost all industries as well as home uses, which is making it more popular among the people. All in all it will be a wise decision to choose a low flow meter rather than going for a traditional one.
