The Difference Between Electromagnetic Water Meter and Ordinary Water Meter
Their Advantages and Disadvantages?
The electromagnetic water meter is a metering instrument specially designed for the actual requirements of water supply enterprises, which can optimize the water supply and ensure accurate water trade measurement and settlement. It conforms to the GB/T778-2007 new water meter standard. Electromagnetic water meters are generally designed with an all-stainless steel casing to ensure that the water meter is used in a highly polluted and corrosive environment, in line with the domestic water meter use environment, with an all-pass structure, zero pressure loss, and no wear. Large turndown ratio, small flow sensitivity, and large flow measurement are far superior to ordinary traditional water meters. The remote monitoring and management software system is used together with the electromagnetic water meter with a remote transmission function, which can not only realize the acceptance 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. Happening. The disadvantage is that its price is high, the structure is complex, 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 casing is cast iron. The inner core is divided into upper, middle, and lower layers. The upper layer can be seen from the glass window, with only the pointer and dial. In fact, the most important thing is the lower layer, where there is a plastic wheel, and there are many plastic blades on the edge of the wheel, which are called "impellers". The water flow hits the blades around the wheel, generating torque that makes the impeller rotate. The wider the faucet is turned on, the faster the water flow, and the faster the impeller turns. The advantages of ordinary water meters are that they are simple and cheap, can be used for a long time in a humid environment without maintenance, do not require a power supply, and power failure does not affect work, so they are still widely used.
