There are three types of water-saving meters in the market.
1, the first type of drip proof Water Leakage table is composed of magnetic sensitive elements with magnetic material for anti leakage mechanism, and the water inlet of the body, when the tap water to drip outward outward flowing water, magnetic pressure-sensitive mechanism will intermittently to water from the water meter, water meter, this way the starting flow meter is less than 0.5 L/H, but the structure of the water meter, as a result of the magnetic pole piston, therefore the fear of the water and mud sand rust, iron and other impurities, the magnetic column is most likely to be stuck with no impurities in the water drip proof function;
2, second types of drip Water Leakage is tubular or holes will be tiny flow into the impeller box tap water meter, impeller and alignment form the core of the jet, will focus on promoting the impeller in a small flow of water up to the impeller rotational kinetic energy, to achieve the purpose of small flow measurement, the the water meter can make the starting flow up to 2 L/H, but the structure of the water due to the small flow in one place on the water jet, it will cause measurement meter, so it will because the water pressure of tap water pipe network instability and make the water table greatly creeping (i.e. in the user will close all faucets without water, due to pipeline pressure instability caused by water meter idling phenomenon), the general creeping up to 192 liters / day (one month without water will empty 5 ~ 6m³ the tap water) , causing the user wronged water, resulting in the occurrence of user complaints and refused to pay water charges, another drawback of this structure is easy to be sand blocking and clamping, over a period of time (usually three to five months) after the loss of anti leakage effect;
3, third types of diaphragm integral drip proof Water Leakage table, it is the case at the bottom of ordinary water the other a cavity, upper structure is still the same with ordinary water, during which the seal separated by a soft diaphragm, bottom cavity outlet is communicated with the water meter shell, the outlet has a special anti drip when the tap water to drip, drip outward form, the first anti drip institutions will still be closed out of the water outlet of a water meter, water meter is a drop of water in the bottom of the cavity, when the bottom cavity of water (Volume 36 ml) was leaked after the anti leakage mechanism will be opened, so as to supplement discharge the water to the bottom of the cavity, the cavity of the water is added after the anti leakage mechanism under the action of the spring and the water outlet seal, and enter the next cycle, the anti leakage mechanism Open up water to the bottom of the cavity is larger than a water meter starting flow process, so the water meter can measure.
