Description
1. Application
Used for household or residential units to measure, memorize and display the volume of cold water flowing through the pipeline. High measurement grade, high sensitivity, high water quality requirements, small flow metering capacity, the more reliable movement material can meet the higher health and strength requirements, installation orientation is not limited.
2. Features
● Adopting volumetric rotary piston principle of measurement, high precision.
● Register is sealed in the capsule with special liquid ensure a clear reading.
● Non-return valve can keep back the backflow.
● Material: Brass, plastic Body for option.
● Non-return valve is available.
● Un-affected by grit and particulates.
● Provided with lead seal and dustproof cover.
● Confirm to ISO4064.
● Available for IP68.
