mm～150mm.
2. Single-jet Water Meter
A single-jet water meter: When water flows through the meter, a single jet of water drives the rotor to rotate. The nominal diameter of single-jet water meters is generally between 15 (or 13) and 25mm, which are relatively small in size, and the error adjustment device is placed externally.
3. Dry Type Water Meter
The dry type water meter isolates its counting mechanism from the water being measured, thus it is not affected by suspended impurities in the water, ensuring the normal operation of the counting mechanism and clear readings. Additionally, unlike wet type water meters, it does not fog or condense droplets underneath the glass due to temperature differences between the inside and outside of the meter, which can affect reading.
The error adjustment device for the multi-jet dry type water meter is generally of an external adjustment type. Its dimensions and internal structure are basically similar to the wet type water meter of the same specifications, and many components are interchangeable.
4. Vertical Water Meter
In spaces with limited installation area, a vertical water meter can be installed. The internal structure of a vertical water meter is the same as that of a standard rotary water meter, with the difference being that the inlet and outlet of the vertical water meter are on the same side of the meter, allowing it to be mounted on the vertical pipe of the water supply system. Vertical water meters offer advantages such as easy reading, no need for protective boxes, and savings on installation costs.
