FUNCTIONS

1. Rotary piston water meter is volumetric water meter, using the principle of piston rotation.

2. High accuracy: the counter is separated from the water.

3. Adopt high-quality materials: stable and reliable performance.

4. Install in the pipeline with good water quality.

5. Inlet are equipped with non-return valve to prevent backflow.

TECHNICAL PARAMETERS

Max. Permission Error (for T30):
From Q1 inclusive up to but excluding Q2 is ± 5%;
From Q2 inclusive up to and including Q4 is ± 2%;

INSTALLATION

1. The installation of water meter should meet the installation requirements of GB/T778.2

2. The caliber of water meter shall be based on the size of the pipeline and the usual used water flow is no more than common flow of the water meter; and the installation location shall be avoided insolation, flooding, freezing and pollution, and convenient for installation, removing and reading data.

3. The sands and stones and other sundries in the pipeline, such as hemp thread shall be cleaned firstly in case of water meter breakdown.

4. Volumetric water meter can be installed in horizontal and vertical

5. Please leave enough space for repairing, and installation according to water flow direction on the pipe.

6. Please do not apply too much force when connecting the rotary liquid sealed water meter and pipe, to avoid damaging the meter body and leakage.

7. If the water meter is installed on the inlet of the boiler, shall install check valve on the outlet of water to prevent the return current of hot water and steam from damaging the water meter.
