Where the LZB-4-6-10 Anticorrosive Fits
The LZB-4F, LZB-6F and LZB-10F are the anticorrosive versions of the small-size LZB glass tube rotameters. In this series the anticorrosive type is intended for measuring corrosive liquid and gas media, and its base is made of PTFE.
They are the compact counterpart to the larger DN15 to DN100 LZB corrosion-resistant bodies and are used where a small direct-reading indicator must handle a corrosive medium.
Construction and Specifications
Sizes are DN4, DN6 and DN10 with dia 11 mm hose-barb fittings. Pressure rating is PN1.0 MPa, the medium temperature range is 0 to +100 °C, accuracy is ±4% of full scale and the range ratio is 1:10.
Liquid ranges run from 1-10 L/h up to 16-160 L/h and gas ranges from 0.04-0.4 m³/h up to 0.25-2.5 m³/h, depending on size.
Ordering Guidance
Confirm the medium, its concentration and the required flow range with the factory, then choose the LZB-F size and connection that matches the line. Do not assume chemical compatibility beyond the PTFE base stated for this type.
