No effected by external magnetic fields.
Pulse output AS OPTION.
Applications of Compound Water Meter
Large residential complexes
In multi-unit buildings, a compound meter can track water consumption for individual units while also measuring overall usage.
Hospitals and Universities
These facilities often have high water demands during peak hours and lower demands at other times, making a compound meter a suitable choice.
Manufacturing and Processing Plants
Industries with varying production processes and water usage patterns benefit from the accuracy of a compound meter.
Different Measurement Technologies of Compound Water Meters
Low Flow Conditions
The low-flow side of the compound meter uses positive-displacement technology… like a diaphragm meter for example. Positive Displacement (PD) meters are very accurate and reliable at lower flow rates and it is resilient for long-term usage because they are less likely to gum up from mineral deposits which is another reason why they are used for residential homes.
High Flow Conditions
The high-flow side of the compound meter usually uses turbine technology. During high flow conditions, the water bypasses the low flow side because it pushes the diaphragm beyond its physical limitations. Basically, it spills over to the high flow side of the meter because the low flow diaphragm meter starts to struggle from the pressure of shoving too much water through it.

Precautions for Installation of Compound Water Meter
Before installing a water meter on a newly laid pipeline, the sundries in the pipeline must be cleaned before installation, so as not to damage the water meter, or affect the normal operation after the water is passed through.
When the water meter is installed, it must be considered that the water pressure and water temperature used on site are within the maximum operating pressure and maximum operating temperature of the water meter.
Water meters installed outdoors should generally be equipped with protective boxes, and should not be installed in places exposed to the sun and frozen to prevent external damage.
Anti-theft should be considered, especially for water meters with copper casings.
For water meters installed outdoors, choosing a location that is dry, anti-sediment, anti-groundwater immersion, and anti-insect entry is necessary.
When the water meter is installed underground, to facilitate the replacement of the water meter, two stop valves must be installed at both ends of the water meter.
Most water meters have installation method requirements. The h on the dial or nameplate means horizontal installation, v means vertical installation, and without these two symbols, it can be installed in any direction.
The water meter should be installed so that the direction of the arrow on the case is consistent with the flow of water in the pipe, and installed coaxially with the pipe.
The dial of the water meter installed horizontally is generally upward and must not be inclined. The orientation of the indicator dial of the reading water meter cannot be adjusted only in consideration of the convenience of reading.
