Selection scheme for seawater turbine flow meter

Location -> News

1、 Summary of Customer Core Requirements

Measurement medium: seawater (highly corrosive)

Flow range: 30-300m ³/h (medium to large flow)

Working pressure: 4MPa (pressure design required)

Temperature range: -20 ℃ to 120 ℃ (wide temperature adaptation)

Connection method: American standard flange 300 pounds (compatible with international standards)

Material requirement: 316 stainless steel (basic corrosion-resistant)

Power supply method: Battery powered (wireless/portable requirements)

2、 Recommended model: CX-LTFM-150-304-P-D-F

Parameter matching analysis:

Parameter customer demand model parameter matching result

Flow range 30-300m ³/h 30-300m ³/h ✅ exact match

Pressure 4MPa 4MPa (pressure design) ✅ meet the requirements

Temperature -20 ℃ to 120 ℃ -20 ℃ to 120 ℃ ✅ coverage

Connection method American standard flange 300 pounds American standard flange 300 pounds ✅ compatible

Material 316 Stainless Steel 316 Stainless Steel ✅ Basic corrosion resistance

Power supply battery power supply battery power supply ✅ meet the requirements

3、 Key risk warning: Corrosive effects of seawater

Limitations of 316 stainless steel:

Although it can resist general seawater corrosion, long-term use (>6 months) may be affected by chloride ion erosion

Wear or jamming of turbine blades

Leakage of flange sealing surface

Shell pitting or cracking

Typical failure scenarios: high salt spray environments such as offshore platforms and coastal chemical plants.

Short term usage suggestions:

Clearly inform the customer that this model is suitable for continuous operation for ≤ 6 months and requires regular inspection.

If the customer needs long-term use (>1 year), the material needs to be upgraded or protective measures need to be added.

4、 Long term usage optimization plan

Material upgrade (increasing cost):

Material corrosion resistance, applicable scenarios, cost increase

316L stainless steel is superior to 316 (low carbon) in mild corrosive environments with 0% corrosion

Dual phase steel 2205 excellent (anti pitting) for offshore platforms and seawater desalination plants+30%~50%

Hastelloy C-276 top-level (chloride ion resistant) chemical and marine engineering+80%~120%
