Acrylic Body Rotameter Manufacturer

Acrylic Rotameter is a Variable Area Flow Meter. It consists of a tapered tube, typically made from acrylic block, with a ‘float’ made of SS or PTFE. The differential pressure across the annulus area is constant. The float moves through the tapered tube up and down with respect to fluid flow. The vertical position of the float as indicated by scale is the measure of the instantaneous flow rate.

Acrylic Rotameters are mainly suitable for Indoor Applications. These Rotameters are used for Air, Water and other non-corrosive fluids.

Introduction to Acrylic Body Rotameter

An acrylic body rotameter is a type of variable area flow meter used for measuring the flow rate of liquids or gases in a closed tube. It is constructed using a clear acrylic block, which allows easy visual observation of the float and flow scale. The transparency and durability of acrylic make it a preferred material for low- to medium-pressure applications in various industries. Acrylic rotameters are lightweight, cost-effective, and resistant to corrosion, making them suitable for laboratory setups, water treatment systems, and chemical processing. The simple design and ease of installation further enhance their utility in both industrial and general-purpose flow measurement needs.

Acrylic Body Rotameter Working

A variable area flow measurement principle is the basis of the working principle of an acrylic body rotameter. It is a vertically oriented tapered acrylic tube containing a float. When fluid flows into the bottom of the rotameter, it rises with the float. The float will be lifted up till the upward force caused by fluid flow will be equal to the downward force of gravity on the float. When this occurs, the float will settle to a steady level, and the flow rate will be read directly on the scale, which is printed on the acrylic body.

Flow rate is in direct proportion to the height of the float. The position of the float can be easily read and monitored since the acrylic body is transparent. The ease and simplicity of this operation cause acrylic body rotameters to be well suited to a wide variety of low-pressure and non-corrosive applications.

Uses of Acrylic Body Rotameter

Acrylic body rotameters are commonly found in many industries because they are easily visible, weigh less, and are economical. These are used commonly in:

What is a rotameter body made of acrylic?

An acrylic body rotameter is a rotameter made of transparent acrylic plastic and used to measure the speed of flow of gases or liquids. Its transparent body allows easy viewing of the float and flow readings inside.

How does an acrylic body rotameter work?

It functions by the variable area principle. When the fluid is added at the bottom, it forces a float in a tube which is tapered vertically up. The float rises until the buoyancy of the fluid is equal to the weight of the float and the height to which it rises is proportional to the rate of flow.

What makes acrylic a good material in rotameters?

Acrylic is noncorrosive, lightweight and resistant to impact and thus it is applied where the pressures are low and the fluid is noncorrosive and where clear visibility of the float is necessary.

Can acrylic body rotameters measure gas flow?

In fact, they can measure both gas and liquid flows, however, only in case they are clean and non-corrosive gases and pressure limitations are followed.

What is the general use of acrylic body rotameters?

They find applications in laboratories, water treatment plants, chemical dosing, aquariums and HVAC due to their low cost and ease of operation, and good visibility.

How often should an acrylic body rotameter be cleaned?

Depending on type of fluid and operating conditions, it should be periodically cleaned. Clean fluids may only require cleaning every three months but particle-containing or dirty fluids may require regular cleaning.

What are the cleaning solutions that can be applied on acrylic body rotameters?

Use soft soaps or cleaning products that are not plastic-destroying. Solvents, alcohol, acetone or any other harsh chemicals that may damage the acrylic surface should not be used.

What can I do to prevent scratches or other damages on the acrylic surface?

Wipe it with a clean cloth or sponge and avoid harsh instruments. Installation and maintenance of the rotameter should be done without treatment because this can make it crack and get scratches.

What would occur should the float be stuck or move abnormally?

Check the flow tube to ensure that it is clean. clean the inside pieces and cause the float to have free movement within the tube. In case of troubles, contact manufacturer.

Are body rotameters in acrylic subject to recalibration?

It is recommended, yes, especially when the rotameter is used in critical applications, that it be recalibrated periodically. It is advisable that calibration be done to give proper readings and this should be done according to the manufacturers specifications.

Can acrylic body rotameters be applied in chemical industries?

They can be used in light chemicals yes. Rotameters made of more chemically resistant materials could however be recommended in cases of very aggressive chemicals.

Are acrylic body rotameters outdoor?

They can also be used outdoors provided they are not subjected to direct sunlight and weather extremes because UV has the potential of wearing the acrylic down over time.

Can these rotameters be used in the pharmaceutical and food processing sectors?

Yes, they are usually used in clean applications of water or other non-polluting liquids where inspection is required visually and hygiene is of importance.

Are acrylic body rotameters appropriate to measure the flow of gases in laboratories?

Absolutely. Their transparent nature and the fact that they provide accurate measurements make them easily visible in labs where they are applied to measure the flow of air, oxygen or inert gases.

What makes acrylic body rotameters suitable in water treatment plants?

Their corrosion resistance, ease of reading, and low maintenance makes them very applicable in monitoring water and dosing chemicals in treatment plants.

Does the acrylic body of the rotameter recycle?

In many applications, yes, acrylic bodies (PMMA, polymethyl methacrylate) may be recycled, depending on the availability of recycling facilities in the area. It should be disposed of like other plastic wastes after cleaning.

What do you do before disposing of the rotameter?

To dispose the rotameter completely, wash out any other remaining fluid, especially that which was used with the hazardous chemicals. This prevents health and environmental hazards.

How do you dispose the metal parts?

Such parts as fittings or connectors (normally stainless steel or brass) can be dismantled and brought to a metal recycling center since they can be reused.

In case hazardous chemicals are used with the rotameter, is special disposal required?

Of course, in the event that the rotameter was used to handle toxic or hazardous materials, then it may be treated as a hazardous waste and discarded in accordance with the local environmental and safety regulations.

Can the entire rotameter be disposed of as ordinary industrial waste?

No, we are not to throw it away as waste. The handling is safe, environmentally friendly, when the material is correctly segregated into plastic, metal, and rubber, and when the regulations of disposal are observed.
