FAQ's of Metaltube Rotameter:
Q: How does the Metaltube Rotameter measure flow accurately?
A: The rotameter uses the variable area principle-fluid passing through a tapered tube lifts a float, whose position is proportional to the flow rate. A magnetic coupled external indicator displays this position externally, ensuring reliable and accurate readings with an accuracy of 1.5% of full scale reading (FSD).
Q: What types of fluids and process conditions can this rotameter handle?
A: This rotameter is suitable for both liquids and gases, with viscosity tolerance up to 200 cP. It can withstand temperatures from -20C to +150C, pressures up to 40 bar, and humidity up to 95% RH (non-condensing), making it ideal for diverse industrial applications.
Q: When should I consider using optional alarm contacts or density compensation?
A: Optional 1 or 2 NO/NC reed switch alarm contacts are recommended for processes where critical flow conditions must be monitored automatically. Density compensation for gases is advised when varying gas densities may impact flow measurement accuracy.
Q: Where can the Metaltube Rotameter be installed?
A: It is designed for vertical (standard) or inline mounting and can be installed in any pipeline with appropriate end connections (flanged, threaded, or tri-clamp). The IP65 enclosure allows for installation in both indoor and outdoor industrial environments.
Q: What is the process for calibration and installation?
A: Each unit undergoes factory calibration to match specific process conditions, ensuring accurate measurements upon installation. Follow the manufacturer's guidelines for mounting and connecting the device, and confirm the chosen calibration and scale meet your application's requirements.
Q: How does the Metaltube Rotameter benefit my operation?
A: It provides dependable real-time flow measurement with minimal maintenance, thanks to its rugged construction and reliable magnetic indication. Optional digital readout, density compensation, and output connectivity streamline process integration and monitoring, enhancing operational efficiency and safety.
