Product Description
Glass Tube Variable Area Flow Meter LZB-4WB Micro Flow Rotameter for Gas Liquid Air Water Panel Mount Precision Use
Glass Tube Variable Area Flow Meter LZB-4WB Micro Flow Rotameter for Gas Liquid Air Water Panel Mount Precision Use1.NOTE
The liquid measurement of this flowmeter is based on water as the reference medium, and gas measurement is based on air. The LZB-4WB series is specifically calibrated for air (gas models) or pure water (liquid models), and must only be used with the corresponding medium. Using other substances—such as mixed gases, hydrogen, ammonia, chlorine, argon, methanol, or acetone—may result in inaccurate readings, irreversible damage, and safety risks. For special media, please provide the required flow range and contact us for a customized solution.
The default fitting is stainless steel barbed fitting. If other types of fittings are needed, please let us know in advance!
