Supmea LZ-SUP HART 4-20mA LCD Local Indicator Industrial Flowmeter Metal Tube Variable Area Flow Meter
The LZ-SUP series from Supmea is a metal tube float flowmeter that measures volumetric flow rate using a variable-area principle. It is built for industrial applications requiring durable and straightforward flow indication or transmission of liquids, gases, and steam.
The instrument consists of a tapered metal measuring tube and a float whose position corresponds to the flow rate. It is available in pointer-type and intelligent versions with digital display options. Features include wide rangeability, multiple process connections, and configurations for high or low temperature service. Signal transmission is achieved via magnetic coupling without direct mechanical contact.

Widely applied in process industries including chemical, petrochemical, water and wastewater treatment, energy, and manufacturing for continuous flow monitoring.
Typical concerns involve installation orientation (must be vertical), float sticking with dirty media, or limited suitability for highly viscous fluids. Selecting the correct material, damping, and range configuration helps minimize these issues.
Can serve as a functional replacement for comparable metal tube rotameters in the same diameter and flow range.
We offer authentic Supmea instruments with experience in matching flowmeters to specific process requirements.
Standard lead time is 6-8 weeks.
