Frequently Asked Questions

Q: Can the Rotameter be used for liquids with high impurity levels?

No, the Rotameter is specifically designed for low-velocity and low-flow media. It is not suitable for media with significant impurities as they may obstruct the float and affect accuracy.

Q: What is the difference between LZM and LZM-G series?

The LZM series is designed for panel mounting with inlet/outlet ports at the back, while the LZM-G series is for direct pipeline installation with ports at the top and bottom.

Q: Which materials are available for the fitting and body?

Bodies are available in Acrylic, PC, PSU, and AS. Fittings can be customized in ABS, PP, PVC, Brass (chrome plated), or Stainless Steel to suit your specific environment.

Q: How should a Rotameter be installed for correct measurement?

Rotameters must be installed vertically. The fluid medium must pass through the instrument from bottom to top to allow the float to rise and indicate the flow rate.

Q: Is the Rotameter compatible with RO water purification systems?

Yes, it is widely used in RO water purification equipment due to its reliability, low pressure loss, and ability to handle clean water flows precisely.

Q: Can I request a custom flow range or thread size?

Absolutely. Customized specifications for flow ranges, thread types (Internal/External), and materials are available to meet your specific industrial requirements.
