Where the LZB-WB Fits
The LZB-WB is a compact micro-flow glass tube rotameter built for instrument panels and laboratory benches. The catalog lists analytical instruments, environmental protection equipment, medical devices and other laboratory equipment as its typical applications.
It differs from the threaded LZB-2/3 micro sizes: the WB line connects by hose, is rated 0 to +60 °C, and the WB version carries an integral adjusting valve so the flow can be set at the meter.
Construction and Specifications
Five tube sizes cover 2, 3, 4, 6 and 10 mm. Water ranges start at 0.4-4 mL/min on the LZB-2WB and reach 0.16-1.6 L/min on the LZB-10WB; air ranges run from 6-60 mL/min up to 5-45 L/min. Accuracy is ±4% on the 2WB-4WB and ±2.5% on the 6WB and 10WB.
Working pressure is up to 1 MPa, with hose connections in 6, 8 or 11.5 mm.
Ordering Guidance
Choose the tube size and span from the range table, the hose diameter, and whether the WB version with integral adjusting valve or the W version without valve is needed.
