LZB Glass Tube Rotameter

The Apure LZB is a glass-tube variable-area flow meter with a visible float and a local flow scale. Choose the scale and wetted materials for the fluid and its operating conditions.

  • Visible float and local scale
  • Glass measuring tube
  • Scale calibrated for the fluid

Reading the glass-tube meter

Flow lifts the float in a vertical tapered tube until it reaches a position corresponding to the flow on the calibrated scale. Read the scale at eye level using the reference edge specified for the supplied float shape. Confirm the scale units and the fluid used for calibration.

Process conditions

Provide the liquid or gas, density, viscosity, flow interval, pressure and temperature. The specification lists liquid service. Ask for a gas-calibrated configuration when measuring gas. Confirm the limits of the glass tube, fittings and seals for the selected assembly, including the effects of temperature and mechanical stress.

The listed 10bar entry is a pressure reference. Confirm the permissible pressure at the operating temperature for the supplied tube, fittings and seals.
