Product Features
YUANKY rotary piston water meter also named volumetric meter works on volumetric measuring principle, measured water enters meter body inlet and drives piston to rotate, each rotation cycle discharges fixed‑volume water and the rotation number of piston will be counted through reduction gear for total water volume registration, remote transmission device can be added upon request and pulse output 0.5L/Pulse is available, it adapts to cold water ≤30℃ and hot water up to 90℃, rated water pressure reaches PN:1.6MPa(16bar), pressure loss meets Class C and R160 standard, its measuring accuracy reaches ±5% from minimum flow‑rate Q1 to transitional flow‑rate Q2, and ±2% from transitional flow‑rate Q2 to overload flow‑rate Q4.
