Product Q&A

Q:What is a rotameter and how does it work?

A rotameter is a type of variable area flow meter that measures liquid or gas flow by observing the position of a float inside a tapered tube. The float rises or falls depending on the flow rate.

Q:What is an ultrasonic flow meter and how does it work?

An ultrasonic flow meter measures flow using ultrasonic sound waves. It calculates the flow rate by detecting the transit time difference or Doppler shift of the sound waves as they pass through the fluid.

Q:What materials are rotameters and ultrasonic flow meters made from?

Rotameters are typically made from glass, stainless steel, or plastic (PP/PVC) depending on the fluid and pressure requirements. Ultrasonic flow meters often use stainless steel, aluminum, or durable plastic for the sensor and housing.

Q:What industries use these flow meters?

Both types of flow meters are used in water treatment, chemical processing, food and beverage, pharmaceutical manufacturing, and industrial fluid systems.

Q:How do I choose the right flow meter?

Selection depends on factors such as flow range, fluid type, temperature, pressure, installation requirements, and whether contactless (ultrasonic) or direct-reading (rotameter) measurement is preferred.
