UPVC magnetic flap level gauge

UPVC magnetic flap level gauge: corrosion-resistant and weather-resistant plastic level gauge

What is the UPVC magnetic flap level gauge?

The UPVC magnetic flap level gauge (full name: rigid PVC magnetic flap level gauge) is a magnetic flap level gauge mainly made of UPVC (non-plasticized polyvinyl chloride) material. It utilizes the principle of a communicator and magnetic coupling technology, enabling an on-site intuitive liquid level display through an external red-and-white flipping column, and can optionally be equipped with a remote transmitter to output a 4-20mA signal or switch alarm.

Compared to PP material, UPVC material has higher mechanical strength, better weather resistance (UV resistance), and a wider lower temperature range, making it especially suitable for outdoor seawater desalination, wastewater treatment, electroplating production lines, and similar conditions.

Comparison between UPVC and PP magnetic flap level gauges

Core advantages of the UPVC magnetic flap level gauge

• Excellent weather resistance: The UPVC material contains UV stabilizers, ensuring long-term outdoor installation without aging or becoming brittle, making it an ideal choice for outdoor storage tanks and outdoor water treatment facilities.

• High mechanical strength: UPVC has greater hardness than PP, stronger bending and compression resistance, and the main pipe is less prone to deformation, making it suitable for high-temperature installation environments.

• Chemical corrosion resistance: Resistant to most acids (hydrochloric acid, dilute sulfuric acid), alkalis, salt solutions, and seawater, suitable for industries such as electroplating, dyeing, and chemical engineering.

• Good flame retardancy: UPVC has self-extinguishing properties, extinguishing immediately after removing from fire, making it safer than PP.

• High cost-effectiveness: The price is comparable to PP, but its service life is significantly better in outdoor environments.

• Optional remote transmission function: remote transmission transmitter can be added to achieve on-site display + remote monitoring.

Technical parameters of the UPVC magnetic flap level gauge

⚠️ Note: UPVC material is not resistant to high temperatures (softens at > 60°C), is not resistant to strong oxidizing acids (concentrated nitric acid, concentrated sulfuric acid ≥70%), and is not resistant to certain organic solvents (such as ketones and aromatic hydrocarbons). For high-temperature or strongly oxidizing conditions, PP or PTFE-lined materials should be selected.

Typical application scenarios of the UPVC magnetic flap level gauge

• Water treatment industry: liquid level measurement of sewage tanks, sedimentation tanks, and clean water tanks (especially suitable for outdoor environments).

• Seawater desalination: resistant to seawater corrosion, suitable for coastal outdoor facilities.

• Electroplating industry: Electroplating tanks, cleaning tanks, and waste liquid collection tank liquid level monitoring.

• Chemical industry: Dilute acid and dilute alkali storage tanks (not high temperature, not strongly oxidizing).

• Environmental protection engineering: acid-base neutralization tank, regulation tank, dosing tank liquid level control.

• Aquaculture/Swimming Pools: Fish ponds, swimming pools, landscape pools, liquid level indicators.

Key points for selecting the UPVC magnetic flap level gauge

Provide the following parameters to the manufacturer to obtain an accurate selection plan:

1. Measurement range: center distance between upper and lower flanges (mm).

2. Media name and concentration: Confirm UPVC material compatibility.

3. Operating temperature: whether within the range of 0°C~60°C (no icing allowed).

4. Working pressure: Is it ≤ 0.6MPa?

5. Installation environment: indoor or outdoor? (Outdoor UPVC recommended, UV resistant)

6. Remote transmission required: 4-20mA / RS485 / alarm switch.

7. Connection flange specifications:D N20/DN25? Standards (China/US/Japan)?

Installation and maintenance of the UPVC magnetic flap level gauge

Installation precautions

• Vertical installation: The main pipe must be vertical, with a deviation not exceeding ±3mm/m.

• Avoid impact: UPVC material is relatively brittle, so avoid knocking and over-tightening the flange during installation.

• Antifreeze protection: UPVC has limited low-temperature resistance; it requires insulation or venting in environments below 0°C.

• Stay away from heat sources: Avoid proximity to steam pipes, heating equipment, and other high-temperature heat sources.

Common faults and troubleshooting

Maintenance recommendations: Regularly check the main pipe for cracks (UPVC aging may become brittle), and clean the inner wall every 6-12 months.
