Product Description
LZM-25ZT Rotameter Acrylic Flow Meter Gas Water Liquid 20-350 Nm3/H Variable Area Panel Flow Meter Water Treatment Industrial
LZM-25ZT Rotameter Acrylic Flow Meter Gas Water Liquid 20-350 Nm3/H Variable Area Panel Flow Meter Water Treatment IndustrialThis LZM gas series is calibrated based on air density [for use with air only].
Use with other gases may result in inaccurate measurements or irreversible damage and safety issues!
The liquid series is calibrated based on water density [similarly, for use with pure water only].
Other special media (e.g., mixed gases, hydrogen, ammonia, chlorine, argon, methanol, acetone, etc.)
require a customized flow range → [Please contact customer service for customization].
1.NOTE
Default Configuration
This flow meter is available with multiple standard flow ranges to suit different working conditions.
Liquid Flow Range for Reference
2-10 GPM / 5-35 LPM
4-14 GPM / 10-50 LPM
6-20 GPM / 20-70 LPM
10-35 GPM / 30-130 LPM
10-40 GPM / 30-150 LPM
15-45 GPM / 50-170 LPM
Gas Flow Range for Reference
20-100 Nm³/h
40-160 Nm³/h
50-250 Nm³/h
35-350 Nm³/h
The recommended operating range is 40-70% of the maximum flow to ensure measurement accuracy and prolong service life. The flow meter must be installed vertically, with careful attention to float reading accuracy.
Optional Features
Custom Flow Ranges
Custom flow ranges are available to meet specific flow measurement requirements for various liquid and gas applications.
Designed for Special Operating Conditions
The tapered tube and float materials can be customized for high-temperature, high-pressure, corrosive, or other demanding process environments.
High-Accuracy Models Available
Enhanced accuracy versions are available for applications requiring more precise flow measurement and control.
Flow Pulsation Stabilization
For applications with unstable or pulsating flow that may cause float fluctuations, installing a buffer or flow stabilizer upstream is recommended to improve measurement stability and reduce reading errors.
Compatibility with Various Fluids
If the standard flow ranges do not match your operating conditions or fluid characteristics, please contact us for professional selection assistance and customized solutions.

5.FAQs
Can this flow meter be used for alcohol or gasoline?
No, it is not suitable for organic solvents like alcohol, gasoline, or acetone.
How should I install the flow meter?
It must be installed vertically with the lowest scale mark at the bottom. Ensure the flow direction matches the indicated markings.
What should I do if the float fluctuates excessively?
If pulsating flow causes instability, install a buffer device upstream of the meter.
