Smart meter Existing limitations and advantages

Advantages of the smart meter-Woltman water meter
With the development of the water meter, this year, the industry in general electromagnetic Water Meters and ultrasonic Water Meters do not take this no activity classified as a water meter smart meter. Lo Wing-meter, water meter rotor with moving parts of mechanical water meters. Smart meter relative to the mechanical meter has many advantages.
Smart meter advantages:
Energy efficiency, smart meter is powered by batteries, power is very small, but also save a lot of meter reading personnel.
Environmental protection, smart meter Sound Guangci way to measure the flow rate of water, the use of non-contact, will not cause secondary pollution of water.
Measurement precision.Woltman water meter
Long-term preservation of historical data.
Controllable water, household water can be controlled.
Smart meter can steal water alarm, water notice, payment reminders, water quality monitoring. Stealing water alarm, if the user stealing water meter can automatically alarm, superior handling requests. In some cases water may be cut off. Trailer without water, if water needs water, water meter can remind users what time without water, ready to remind the user to do without water. Payment reminder, if the user's prepaid water has been used up, the meter can remind users to pay. Water quality monitoring, water quality meter can detect and display the current water quality is qualified.
In the era of big data, smart meter plays an important role in data collection and storage. If large data compared to a skyscraper, it is the only meter skyscraper foundation. The Foundation directly supports it as high as the sky building, provide strong support for the building. Smart meter can collect water temperature, water quality, real-time curve of water. Based on these data, the use of cloud computing and cloud storage.
Existing restrictions smart meter
Currently, the smart meter general power supply in two ways, one is external 220V power supply; the other is a 3.6V battery. On the current situation, the meter application environment is very complex. Many places can not get 220V power supply, even with 220V power supply will increase the number of project cost. Therefore now most of the smart meter with 3.6V battery. Then battery-powered application field can not solve the water meter supply problems. However, there are several disadvantages battery powered:
Battery capacity
Currently one 18505 battery can be used for ultra-low-power design of the meter with 8--10 years. However, with the growing number of smart meter functions, such as GPRS remote, high-precision measurement, flow rate measurement of high frequency wireless networking with valve-regulated, these are the cells can not afford.Woltman water meter
Battery size
Smart meter miniaturization future may even directly into the pipeline. The battery will be nowhere to place.
