Liquid Volumetric Positive Displacement Meter

Liquid Volumetric Positive Displacement Meters are instruments used to measure the flow rate of liquids. They belong to the supply class "Liquid And Gas Flow, Liquid Level, And Mechanical Motion Measuring Instruments" in the supply group "Instruments And Laboratory Equipment".

These meters work based on the principle of positive displacement, where a fixed volume of liquid is measured and then displaced to determine the flow rate. They are commonly used in industries such as oil and gas, chemical processing, water treatment, and food and beverage.

Liquid Volumetric Positive Displacement Meters are known for their high accuracy and repeatability, making them suitable for applications that require precise measurement of liquid flow. They are often used in custody transfer applications, where accurate measurement is crucial for billing purposes.

These meters typically consist of a chamber or rotor that rotates as the liquid flows through it. The rotation of the chamber or rotor is directly proportional to the volume of liquid passing through, allowing for accurate measurement. The meters are equipped with sensors or mechanical mechanisms to detect and record the rotation, which is then converted into flow rate data.

Liquid Volumetric Positive Displacement Meters are available in various sizes and materials to accommodate different types of liquids and flow rates. They can be installed in-line with the piping system or used as portable devices for on-site measurements.

Overall, these meters provide reliable and accurate measurement of liquid flow, making them essential instruments in industries that require precise control and monitoring of liquid processes.
