1.The semi-liquid cover plate is clearer. The counter part is vacuum treated and isolated from the outside air and the measured water, so it is not easy to atomize to keep the counter clear. 2.Enlarge the inner cavity and reduce pressure loss. Under the condition of ensuring performance, the increase of the water inlet and outlet holes of the impeller box can effectively reduce the pressure loss of the water meter. 3.Install lead seals to prevent water stealing. The lead seal is added after strict inspection before leaving the factory, which means that the product is qualified, and it can also prevent tampering and increase safety. 4.High standards guarantee sensitivity. Accurate to 0.0001, combined display of numbers and pointers. 5.All copper fittings. Anti-rust full copper joints, equipped with leak-proof sealing ring. Product model: TS-S300E Wing structure: Rotary wing Pressure rating: less than equal 1.0MPa/1.6MPa Installation method: Horizontal installation Why is there water in the dial? 1.This water meter is a semi-liquid sealed water meter, which is sealed with a certain concentration of compound liquid. 2.The liquid seal can prevent dirt from entering the dial to block the line of sight and affect the reading. 3.Prevent foreign matter from affecting the operation of the gear mission mechanism when the water quality is poor, affecting the measurement accuracy and service life. 4.It is not easy to be interfered by other factors such as strong external magnetic field, rust in water, natural demagnetization and so on. Why is there water flowing out of the water meter? 1. When the water meter is tested, the water is tested, so there will be water in it. 2. The remaining water will not affect the internal structure of the water meter, and there is no need to control it. 3. The water in the dial is sealed and no sealing liquid will flow out.
