For peers working in water purification, sewage treatment and chemical dosing: choosing the right pipe flow monitoring parts can greatly cut maintenance troubles! Today I’d like to share an essential product for the industry — LZS plug-in plastic tube precision rotameter.
Four Core Advantages
✅ Quick plug-in connection
Integrated plug connector to directly connect pipelines. No flanges or welding required. It only takes a few minutes to disassemble, assemble and clean the rotor, doubling on-site construction efficiency.
✅ Corrosion and impact resistant, hard to break
The plastic tube body works well with sewage, acid and alkaline chemicals. Compared with glass flowmeters, it resists bumps and won’t crack or leak easily when installed outdoors or in workshops.
✅ Standard measuring accuracy of ±4%
Available in long-tube and short-tube versions. It delivers accurate readings for small-flow chemical dosing lines and large-flow water production pipelines, helping you strictly control chemical costs.
✅ Compatible with most common water system conditions
Applicable medium temperature: 0~60℃, maximum pressure resistance: 0.6MPa. It operates stably on pure water, circulating water and sewage pipelines.
Full range of sizes available, pick the right model without mistakes
Models cover six calibers from DN15 to DN65, matching various pipe sizes and flow requirements:
DN15/DN20: Small pure water machines, micro chemical dosing
DN25/DN32: Standard matching for reverse osmosis RO systems
DN40/50/65: Main pipelines for large sewage treatment, reclaimed water recycling and circulating water
Tips
Choose the short tube type (with built-in guide rod) if your installation space is limited.
Pick the long tube type for stable readings and long-term continuous operation.
Applicable Industries & Scenarios
Reverse osmosis pure water equipment, integrated sewage treatment, chemical dosing systems, central air conditioning circulating water, electroplating cleaning, water softener pipelines.
Tips for Model Selection & Installation to Avoid Problems
1.The flowmeter must be installed vertically, with water flowing upward. Tilting will lead to inaccurate readings.
2.For wastewater with impurities, install a filter in front of the meter to prevent the rotor from jamming.
3.Plastic versions are not recommended if the medium temperature exceeds 60℃ or pressure exceeds 0.6MPa.
4.This compact flowmeter helps control chemical costs and keep equipment running stably. It is a standard spare part widely stocked by equipment manufacturers and engineering contractors!
5.If you have questions about model selection, dimensions or flow ranges, feel free to message me for customized solutions.
