The difference between electromagnetic water meter and ordinary water meter, advantages and disadvantages

Electromagnetic water meter is a measuring instrument specially designed for the actual requirements of water supply enterprises. It can optimize water supply and ensure accurate water trade measurement and settlement. It meets the GB/T778-2007 new water meter standard. Electromagnetic water meters are generally designed with an all-stainless steel case to ensure that the water meter is used in a highly polluted and corrosive environment, which is in line with the domestic water meter use environment. It has an all-through structure, zero pressure loss, and no wear; super large range ratio, small flow sensitivity and super large flow measurement are far superior It is a common traditional water meter. The remote monitoring and management software system is used in conjunction with the electromagnetic water meter with remote transmission function, which can not only realize the reception and storage of flowmeter data, but also realize the statistics and analysis of flow data, which can facilitate and timely control the water consumption of each flow measurement point in the area. Condition. The disadvantage is that its price is relatively high, the structure is complicated, and it needs a power supply to be used normally.

The internal structure of ordinary water meters (traditional water meters) can be divided into three parts: shell, sleeve and inner core from the outside to the inside. The shell is cast iron. The inner core is divided into three layers: upper, middle, and lower. What you see from the glass window is the upper layer, with only pointers and dials. In fact, the most important thing is the lower layer. There is a plastic wheel inside, and there are many plastic blades on the side of the wheel, which are called "impellers". The water flow impacts the blades around the wheel, generating torque, which causes the impeller to rotate. The larger the faucet opens, the faster the water flow, and the faster the impeller will turn. The advantages of ordinary water meters are that they are simple and inexpensive, and can be used in a humid environment for a long time without maintenance, and they do not need a power supply, and the power failure does not affect the work, so they are still widely used.
