Updated: Dec 21, 2023

In various industries, accurate fluid measurement is vital in ensuring efficiency, quality control, and safety. The digital inline nutating disc poly chemical transfer meter distinguishes itself as a reliable and effective option among the several instruments available for chemical transfer.


In-depth information about this meter’s operation, applications, benefits, technical details, installation, calibration, maintenance, and safety issues will all be discussed in this article. By the end, we will comprehend why an efficient fluid measurement requires the use of a digital inline nutting disc poly chemical transfer meter.


Nutating disc technology is used by the digital inline nutating disc poly chemical transfer meter to measure fluid flow.


It is made of a disc that nutates, or wobbles, inside of a chamber. The disc rotates as the fluid flows through the chamber, producing a rotating motion proportionate to the flow rate. Then, for precise measurement, this rotating motion is transformed into digital signals.


Durability and chemical resistance are the two main characteristics that were taken into account while designing this meter. It can be used for a variety of purposes because of the polymeric components that are incorporated into its manufacture and can endure the harsh impacts of various chemicals.

An overview of the main characteristics and operation of the Digital Inline Nutating Disc Poly Chemical Transfer Meter is given below:


i. Nutating Disc Design


The digital inline nutating disc poly chemical transfer meter measures liquid flow using a nutating disc mechanism. The nutating disc is a circular disc that rotates in a distinctive pattern to create a chamber that fluctuates in volume as the liquid flows past it.


ii. Inline Installation


The Nutating disc meter is often positioned in line within a piping system to let the liquid pass through it. It has threaded fittings or flanged connections for simple integration into the current pipeline.


iii. Chemical Compatibility


The digital inline nutating disc poly chemical transfer meter is made specifically to work with corrosive liquids and chemicals. It is made of polymeric materials with strong chemical resistance, including polypropylene or polyvinylidene fluoride (PVDF).


iv. Digital Display


The digital inline meter has a digital display that shows current statistics on the flow rate, total volume, and other pertinent information. This enables operators to keep an eye on the transfer procedure and guarantee precise measurement.


v. High Accuracy


When monitoring flow rates, the nutating disc design offers a high degree of accuracy. Even when dealing with fluids of various viscosities and densities, it guarantees consistent performance.


vi. Wide Flow Range


The Digital Inline Nutating Disc Poly Chemical Transfer Meter can be purchased in a variety of sizes and models, providing a wide range of flow rates to fit different applications. It is excellent for various industrial operations since it can manage both low and high flow rates.


2: Working Principle 


A nutating disc mechanism is used in the operation of a Digital Inline Nutating Disc Poly Chemical Transfer Meter, to measure flow accurately.

The principle of fluid displacement is used to operate this meter. When fluid passes through the meter, it enters a chamber with a nutating disc that is positioned asymmetrically on a central axis.

The nutating disc moves in a circular motion as the fluid goes through the chamber, coming into contact with the chamber walls in the process. The fluid volume between the disc and the chamber walls will be determined as a result of this contact and is then measured.

With the help of digital electronics involved in the Nutating disc meter, it is possible to precisely measure the fluid flow by maintaining track of the number of mutations or disc rotations. The meter is suitable for handling fluids under moderate pressure circumstances.


3: Operating Principles


A Complete Guide – Digital Inline Nutating Disc Poly Chemical Transfer Meter

A Digital Inline Nutating Disc Poly Chemical Transfer Meter works on the principles of nutating disc technology, flow measurement, and signal transfer with a digital display.

Let’s explore each of these parts in more detail:


i. Nutating Disc Technology


The nutating disc, the most important component of the Digital Inline Nutating Disc Poly Chemical Transfer meter, is in charge of determining the flow rate of the liquid that is being transported. It comprises a disc supported by a ball in the middle.

The liquid enters a chamber with the nutating disc as it passes through the meter.

The flowing liquid’s pressure pushes against the disc, causing it to “nutates” or wobble. This nutating motion establishes a clearly defined flow route and makes it possible to measure the fluid going through the meter accurately.



ii. Flow Measurement Mechanism


Nutting disc technology allows us to measure fluid flow based on disc movement. The chamber that contains the nutating disc is meant to control liquid flow and provide the necessary pressure to drive the nutating process. 

The liquid strikes the disc as it moves through the chamber, moving it. The volumetric flow rate of the liquid determines how the disc wobbles. The flow rate can be measured by counting the disc revolutions or by measuring the angular displacement.


iii. Signal Transmission


The Digital Inline Nutating Disc Poly Chemical Transfer Meter is equipped with a signal transmission system that relays the flow measurement information to external devices or displays.

Typically, this involves the use of sensors or transducers that detect the disc’s movement and convert it into an electrical signal. The signal is then transmitted to a control unit or a display device for further processing and presentation.


iv. Digital Display

The Digital Inline Nutating Disc Poly Chemical Transfer Meter incorporates a digital display that provides real-time information about the measured flow rate. The digital display unit receives the electrical signal from the sensor or transducer and converts it into a readable format, such as numeric values or graphical representations. The display unit may also include additional features like totalizers, which accumulate the total volume of fluid transferred over time.

Overall, the Digital Inline Nutating Disc Poly Chemical Transfer Meter utilizes nutating disc technology to measure the flow of fluid. The nutating disc’s movement is translated into an electrical signal, which is then transmitted to a digital display unit for real-time monitoring and accurate flow rate readings. This type of meter is commonly used in applications where precise measurement of chemical transfer is required.
