Where the LZB Standard Type Fits

The LZB standard glass tube rotameter is a flange-connected variable-area meter for liquid and gas measurement, with a clear direct-reading glass scale. It is the standard (common) type in the LZB series.

Construction and Specifications

This is the standard (common) LZB type in DN15 to DN100. Accuracy is typically ±2.5% of full scale, with ±1.5% on the smaller sizes. The range ratio is 1:10, and approximately 1:5 for DN80 and DN100.
Pressure rating is PN0.6 MPa for DN15 through DN50 and PN0.4 MPa for DN80 and DN100. The medium temperature range is 0 to +100 °C. Both liquid and gas measuring ranges are listed by size in the catalog tables.
