Positive displacement flow meters measure the amount of liquid that passes through it. By design, two or more discs in the flow path move closer together as fluid flows through the meter and apart from when no liquid flows through the meter. 
The movement of the discs generates an electrical signal which can calculate the flow rate by measuring the frequency of oscillation between two points. The major applications of a positive displacement flow meter include:

Petroleum Refining
Petroleum refining is essential for extracting crude oil and other natural sources. It converts these fuels into jet fuel, diesel, propane, heating oil, kerosene, and petroleum coke. 
Positive displacement flow meters commonly measure heavy hydrocarbon flows in continuous distillation columns in refineries. They are also used in pipelines to measure mixed liquid hydrocarbons.

Crude oil storage
Oil is generally stored in reservoirs (below ground or on-shore) located away from populated areas. This water flow meter monitors and measures how much oil is removed from the pool. 
It sends its data to a computer then calculates how much oil needs to be added back into the reservoir to keep it optimal. If there’s too much pressure, pumps draw off more oil; if there’s not enough pressure, they fill it up with more oil.

Process/Bulk solids handling
When measuring the water flow, it is usually related to quantity. Whether you are taking inventory on the material in storage, or pumping product from one vat to another, it is essential to know how much is moving through a pipeline. 
The most common technology used for bulk solids handling and measurement is the water flow meter known as the positive displacement meter.

Measuring liquids in tanks and reservoirs
By far, positive displacement flow meters are best suited for measuring liquids in tanks and reservoirs. For these applications, it’s essential to measure high volumes of liquid in tanks, ranging from 5–100 feet tall.

Measuring water in streams, rivers, and lakes
Water flow measurement is an essential part of water management. High-accuracy positive displacement flow meters commonly measure water velocity and volume in streams, rivers, and lakes. 
The measurement is achieved by measuring two or more points along a stream, with multiple devices installed at those positions. Velocity and depth can then be calculated using simple math, making calculating mean depth across long distances possible. 

This data can be used for hydrological purposes, monitoring stream health, and understanding runoff processes.

Measuring fluid flow in mines and tunnels
One of the most dangerous parts of working in mines and tunnels is knowing if enough oxygen is in a particular area. The only way to accurately measure oxygen flow and other gas concentrations is by using positive displacement flow meters. 
These devices can be configured for various gases, fluids, solids, and particles. Using these instruments can protect miners from exposure to hazardous materials and help prevent tunnel collapse.

Final Words
Positive displacement flow meters are types of water flow meters that usually help measure the flow rate of water. Each type of these flowmeter has its applications where they are best suited. For instance, a positive displacement is essential in many different industries like petroleum refining, the storage of crude oil, handling process or bulk solids, measuring the fluids in tunnels and mines, etc.
