The principle of action of the rotary water meter is; water enters the case from the water meter inlet, through the water filter, enters the impeller box by the inlet hole of the impeller box, impacts the impeller, the impeller starts to rotate, the water then flows into the pipe by the upper outlet hole of the impeller box through the case outlet, the lower part of the impeller is supported by the thimble. After the impeller rotates, through the central shaft of the impeller, the central gear in the upper part also rotates, driving the transmission gear in the impeller box to rotate according to the speed ratio, driving the pointer on the dial. The triangular pointer starts to rotate and then drives the other gears and the upper pointer in a decimal transfer, which starts to rotate in a clockwise direction in accordance with the index value on the dial, starting from 0 and starting to measure.
1. High accuracy, accurate measurement.
2. Convenient maintenance.
3. Technical indicators up to GB / t778.1 ~ 3-2007 standard
4. Dry counter separated from the measured water can keep clear indication for a long time, parts in contact with water are made of high-quality anti-corrosion and anti fouling materials.
5. And standard pipe thread is used for DN 15 ~ 50.
6. It can be equipped with wireless and wired remote transmission function to realize the intelligent metering terminal of remote meter reading.
7.Dry dial Brass body Brass fittings,longer life.
The maximum allowable error of low zone is as follows:
The maximum allowable error of discharge volume between minimum flow (Q1) and boundary flow (02) (excluding Q2) is ‡ 5%
Maximum allowable error in high range:
discharge volume is + 2% based on the flow between boundary flow (Q2) (including Q2) and overload flow (Q4).
