Where the LZB-2-3 Fits
The LZB-2 and LZB-3 are the small-size glass tube rotameters in the LZB family. They are used where very low liquid or gas flows must be read directly, in laboratory, analytical and sampling duties.
They are distinct from the DN15 to DN100 LZB standard and corrosion-resistant versions: the LZB-2-3 bodies are DN2 and DN3 with an M8x1 external thread.
Construction and Specifications
Both sizes carry a pressure rating of PN1.0 MPa and a medium temperature range of 0 to +100 °C. Accuracy is ±4% of full scale for the standard type, with a 1:10 range ratio.
Liquid ranges are tabulated in ml/min and gas ranges in ml/min up to L/min. All-stainless (B) and anticorrosive (F) variants are listed in the catalog.
Ordering Guidance
Confirm the medium, the required micro flow range and the connection, and whether a standard, all-stainless or anticorrosive variant is needed.
