The Volumetric Piston Water Meter achieves high accuracy through direct volume measurement, where a precision piston displaces a known volume per cycle.
Product Description
Application:
The Volumetric Piston Water Meter achieves high accuracy through direct volume measurement, where a precision piston displaces a known volume per cycle.
Key Features:
• Ultra-High Accuracy: Meets high-level metrological classes (e.g., R160/R200/R315).
• Low Starting Flow: Detects minimal water usage with exceptional sensitivity.
• Universal Installation: Maintains precision in horizontal, vertical, or inclined positions.
• Volumetric Principle: Measures the actual volume of water for unmatched reliability.
• Magnetic Drive: Ensures smooth transmission with a vacuum-sealed register.
• Inlet Strainer: Integrated filter protects the precision piston from debris or impurities.
• Non-Return Valve: Prevents backflow and protects against billing tampering.
Specifications:
• Body material: Brass
• Accuracy: R160/ R200/ R315/ R400
• Size: DN15-20-25-40
• Cold water: 0 ℃ - 50℃
• Hot water: 0 ℃ - 90℃
• Water pressure: 1.0MPa / 1.6MPa
• △P≤63
• Connecting threaded option: G/ BSP/ NPT
• Pulse output option: 1P=1-10L
Installation:
• Can be installed in any position (horizontal, vertical, or inclined) without affecting accuracy.
• A strainer must be installed to prevent sand or particles from jamming the piston.
• Ensure the pipeline is fully purged of air to avoid measurement errors or rattling.
Accuracy:
• From minimum flow rate (Q1) inclusive, to transitional flow rate (Q2) exclusive: ±5%
• From transitional flow rate (Q2) inclusive, to overload flow rate (Q4) exclusive: ±2%
• Hot water meter ±3%
