Key Features

High Accuracy

This Glass Rotameters offers an accuracy of 4%, ensuring precise measurements for applications such as clean water flow monitoring.

Customization Options

The product offers OEM and ODM customization support, allowing users to tailor the rotameter to their specific needs.

Durable Construction

The rotameter features a durable plastic tube and flange design, making it resistant to corrosion and wear and tear. This makes it an ideal choice for users who need a long-lasting flowmeter, such as those working in harsh environments.

Wide Range of Applications

With a nominal diameter range of DN15-
DN150 and a pressure rating of 0.6MPa, this rotameter can be used for a variety of applications, including water treatment, chemical processing, and more.

Types of Glass Rotameterss Available

Acrylic Rotameter

An acrylic rotameter is preferred for low-pressure applications. These applications include water treatment and aquaculture. It has a durable and lightweight structure made of acrylic.

Steel Rotameter

If the client is looking for a rotameter that will last through any harsh environment, the steel rotameter is the ideal choice.

rass Rotameter

If the client is price-conscious but looking for quality, then brass rotameters are a good compromise. As with the steel types, brass rotameters have high durability.

PVDF Rotameter

This type of rotameter is constructed from polyvinylidene fluoride. PVDF rotameters are ideal to use in environments that have chemical exposure.

Applications

Chemical Industry
Rotameters are used here to measure the flow of various liquids and gases. These liquids and gases can range from corrosive chemicals to viscous fluids.

Water Treatment
Water treatment facilities use glass tube rotameters to measure the flow of water and chemicals for treatment processes. Monitoring the flow ensures efficient operation during the treatment of drinking water, wastewater, and water for industrial use.

Pharmaceuticals
In the pharmaceutical sector, glass tube rotameters are used to measure gas and liquid flow. They ensure accurate measurements for life-saving drugs and other medical equipment.

Food and Beverage
This industry has rigorous rules to follow. Because of this, manufacturers prefer glass rotameters during processing and quality control. These users measure the flow of liquids like syrups, juices, and beer.

Precautions

Installation, try to stay away from the external magnetic interference devices, such as large motors.

Fluid medium can not contain ferromagnetic impurities

Should be installed in the pipe vibration, in order to prevent malfunction of the switch contacts.

FAQ

Q: Do these Glass tube rotameters need maintenance?

A: These rotameters are low-maintenance. Periodic checks on the rotameter accuracy and wear are normally enough maintenance.

Q: Can borosilicate glass rotameters be used for both liquids and gases?

A: Yes, most glass rotameters measure both liquids and gases. However, buyers should check with manufacturers for specific usage.

Q: What are the common sizes of a glass tube rotameter?

A: These rotameters are usually between 1/4 to 2 inches in diameter. The length is normally between 300 to 500 millimeters.

Q: Are these glass tube rotameters accurate?

A: Glass rotameters are normally accurate under normal conditions. Their accuracy decreases under extreme conditions, such as high pressure and temperature.

Q: Are these glass tube rotameters suitable for outdoor use?

A: No, glass rotameters are not suitable for outdoor use. They are ideal for indoor use, where temperatures and pressures are moderate.

Q: What is the principle of rotameter in glass tube?

A: The operation of a rotameter is based on the variable area principle. That is, the flow of a liquid raises the float inside a tapered tube, increasing the area through which the liquid can pass. The larger the flow, the higher the float will be raised.

Q: Why is a metallic rotameter preferred over a glass rotameter?

A: Unlike glass tube rotameters, which are more common for lower pressures and clear visibility, metal tube rotameters are typically used in environments where the fluid is turbid, high-pressure, or chemically reactive.

Q: How does rotameter usually get damage?

A: Different flow rates can be measured using various floats. For ease of reading, it's helpful to position a glass tube rotameter at eye level. However, glass tube rotameters are not suitable for certain fluids, such as water above 194 °F (90 °C), high pH fluids, and wet steam, which can damage the glass.
