Flowmeters

LZS‑E series brown glass Line Mount

LZS‑E series brown glass rotameter is a vertical, variable-area flowmeter with anti-corrosive brown-tinted glass (or brown glass-like plastic)—ideal for visual monitoring of liquids and some gases in industrial processes.

Flow is measured as the fluid enters from the bottom, lifting a float inside the tapered tube; the float’s vertical position corresponds to the flow rate, read on the graduated scale.

This flowmeter is ideal for monitoring clean water and non-corrosive liquids in industrial processes, water treatment systems, cooling systems, and chemical dosing applications.
