Supmea LZ-SUP Metal Tube Float Flowmeter
The Supmea LZ-SUP (also referred to as SUP-LZ) is a metal tube variable area flowmeter designed for reliable volumetric flow measurement of liquids, gases, and steam in closed pipelines. It operates on the float principle within a tapered metal tube and is suitable for industrial process control environments.
Product Overview
This metal tube rotameter features a robust all-metal construction that handles a wide range of process conditions. It offers a standard range ratio of 10:1 (optional 20:1), multiple connection options, and versions for local indication or remote signal output. The design supports non-contact magnetic coupling for signal transmission and provides good resistance to vibration and harsh media when configured appropriately.

Application Industry
Used in chemical processing, petrochemical plants, water treatment, power generation, pharmaceutical production, and general industrial process control for measuring liquid and gas flows.
Common Problems
Users may encounter issues with media viscosity, vertical installation requirements, or signal transmission in difficult environments. The metal tube design and magnetic coupling help improve reliability compared with glass tube versions, while proper selection of materials and range addresses many process challenges.
Replacement Models
Suitable as a replacement for other metal tube variable area flowmeters of similar size and performance in existing installations.
