Water Flow Meters

Key Features for Aquaculture/Aquariums (Water):
✅ Short Models (304SS Guide Rod): Suitable for freshwater systems with turbulent flow (e.g., sump returns, biofilter loops).
✅ Long Models (No Guide Rod): Ideal for saltwater or algae-heavy environments (e.g., UV sterilizers, dosing lines).
✅ Silicone O-Rings: Resistant to saltwater, chemicals, and UV degradation.

Technical Specifications (All Models):

• Pressure Limit: 6 bar
• Temperature Limit: 60°C
• Mounting: Vertical installation (flow direction: bottom to top).
