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%
