In addition to the pharmaceutical industry, the metallurgical industry, and the petrochemical industry, the metal tube rotameter is a type of variable area flow meter that sees widespread application in the food processing industry. When measuring flow in pipes with a small diameter (DN) and in media with a low flow rate, it is especially helpful to have this tool. The flow rate is moderately slow in both of these scenarios.

The variable area principle is adhered to by rotameters that are made up of metal tubes and function according to the aforementioned principle. A float is typically attached to the end of a tapered tube that is manufactured out of steel. This is done so that the float can float freely. The quantity of fluid that is housed inside the metal tube causes the float that is housed inside the tapered tube to rise, which in turn results in an increase in the area that fluid is able to pass through. A magnetic coupling, a chain of linkages, and a counterweight work together to produce the desired effect, which is the movement of the inner float. This movement is achieved by utilizing a chain of linkages and a counterweight. The amount of flow that is generated by the system is determined by the way in which the tube and the float communicate with one another.

Why do such a large number of people favor utilizing rotameters that are constructed from metal tubes? To get things rolling, the apparatus is made entirely out of metal, which provides it with the ability to function normally in environments that are either extremely hot or have a high level of corrosion. This is just the beginning of what's to come. Second, it has been tested, and the results of those tests showed that it complies with the ExiaIICT6 and ExdIICT6 standards. This means that it is safe to use in environments where there is a possibility of an explosion happening. Thirdly, it is capable of measuring liquids, gases, and steam, which gives it a wide range of potential applications in a variety of industries. This opens up a lot of doors for the company. Additionally, the Holykell metal tube rotameter can receive its power from either direct current (DC) or batteries, making it exceptionally flexible. In addition to this, it is simple to set up and places very few demands on the segment of straight pipe that is being utilized in the process.

As a result of the extensive variety of benefits that they offer, metal tube rotameters are quickly gaining popularity across a wide variety of business sectors. This is due to the fact that they are extremely cost-effective.

ROTAMER FOR THE STAINLESS STEEL TUBE

Rotameters are a type of variable area flowmeter that are constructed out of tubes made of metal. The volumetric flow rates of gases and liquids can both be measured with these flowmeters thanks to their versatility.

There is a tube inside of it that is constructed out of stainless steel that is tapered, and it is an integral part of the construction.

A float that has a magnet attached to it and can be moved along inside of a tube that tapers to a point at one end is described as a magnetic float.

The float and the indicating pointer assembly are connected via a magnetic coupling, which serves as the connection point between the two components.

- The buoyancy force was neutralized by the gravitational field, which resulted in the subject remaining in a floating position while they were encased in the tube

- This was able to be accomplished because the gravitational field was pulling in the opposite direction

- When the flow tube on the inside is tapered, there will be a gap between the float's outer diameter and the inside wall of the tapered tube

- This gap is created when the flow tube is tapered on the inside

- The gap is the name given to this space

- After that, there will be a passage opened for a flow of liquid to take place through this area

- The magnetic coupling causes movement in the indicating pointer assembly, which in turn causes movement in the flow rate indicator when the float moves in a vertical direction inside the tube

- This movement is caused by the float's travel inside the tube

- This entire motion is being brought about by the interior of the tube

- An additional feature that can be added to Eureka Metal Tube Rotameters is known as an electrical transmitter output, and this capability is available as an option for purchase

- In addition to the analog output of 4-20 mA that is offered, it is also possible to use HART communication

- This is a feature that is available

CE/PED approvals and Ex/ATEX versions are also offered so that the product can successfully fulfill the requirements of a wide variety of applications.

The models are able to measure very low flow rates of up to one liter per hour, in addition to very high flow rates of up to tens of thousands of liters per hour. In addition to that, the models have the capability of measuring extremely high flow rates.

It is obtainable in a huge selection of various versions, some of which include the software applications that are detailed in the following list:

A ROTAMETER MADE UP OF A METAL TUBE THAT HAS AN ELECTRICAL TRANSMITTER INSTALLED IN IT

In the case of metal tube rotameters, it is possible to provide an analog electrical output that has a range that is between 4 and 20 milliamperes and that is proportional to the flow rate of the fluid. This range can be anywhere from 0 to 100 milliamperes.

It is possible to determine the location of a pair of magnets that have been mounted on a shaft assembly with the assistance of a Hall effect sensor. These magnets have been mounted on the assembly.

When the analog pointer is turned in its rotary motion, this causes the output of the Hall effect sensor to move, which in turn causes the analog pointer to move.

An electronic circuit is used to process this output, which ultimately results in the generation of current output that is proportional to flow rate. This output is then passed on to the next stage of the process.

There is a wide variety of iterations of the electrical transmitter that are available to be purchased, and each and every one of these iterations is suitable for use in applications that can take place in either a safe or hazardous environment.
