Multi-jet Vane Wheel Dry-dial Cold Or Hot Water Meter
Measuring the total volume of cold (hot)water passing through the pipeline. This type of water meter can be used for a remote reading transmission system as equipped with a built-in-sensor.
By setting a special flow guiding structure at the inlet, it "disperses" a single water flow into multiple water streams, which impact the impeller more evenly from different angles, thereby achieving high measurement accuracy and stability over a wider flow range.
