Introduce in detail the features of IC card prepaid water meters and NB-IoT remote water meters
There are many types of smart water meters on the market today. There are three popular smart water meters: IC card prepaid water meters, LONA wireless water meters, and NB-IoT remote water meters. Today, we mainly talk about the characteristics of IC card prepaid water meters and NB-IoT remote water meters.
IC card prepaid water meter
The IC card prepaid water meter has the functions of automatic settlement and automatic billing. The user submits the recharge amount to the water supply management department, and the staff writes the amount of water purchased by the user into the IC card, which can be used normally after the user swipes the card; the microcomputer of the IC card prepaid water meter will automatically deduct the cost after each water consumption (reduce the total water consumption Therefore, after using the IC card prepaid water meter, the charging work of the water supply department and the water consumption of residential users will be more convenient! However, to talk about the advantages of IC card prepaid water meters, it must be the prepaid function of this water meter. It is precisely because of the existence of this function that the problems that users often encountered in the water supply department in the past, such as non-payment of water bills, arrears of water bills, slow recovery of water bills, etc., can be solved one by one. This is why it is in the water meter market today. main reason for popularity.
NB-IoT remote water meter
NB-IoT remote water meter is compared with manual meter reading work. It is a non-manual automatic metering method. It can directly read the meter automatically without the need for a meter reader to come to the door, and then transmit the water consumption data to the management and control platform. The unit provides water consumption data for the convenience of people. The installation of NB-IoT remote water meters can better solve the problem of remote meter reading and charging, and realize the remote metering mode. Many water meter manufacturers claim that their water meters have remote valve control and good water resistance. But in fact, only a wireless remote transmission water meter that realizes computer remote control, network recharge and IP68 protection level can truly be called an intelligent wireless remote transmission water meter. The NB-IoT remote water meter uses a wireless smart meter reading system. The meter reading system is based on the cellular narrowband Internet of Things technology, and remotely reports water consumption information through the dedicated number transmission channel of the Internet of Things private network. It does not require manual meter reading, and has the advantages of wide coverage, high reliability, high use efficiency, low installation cost, low power consumption, and long use time.
For the installation of IC card prepaid water meters and NB-IoT remote water meters, the convenience of maintenance and replacement of water meters should be considered at the installation location. For water meters installed outdoors, a dry, silt-proof, groundwater-proof, and insect-proof location must be selected. When the water meter is installed underground, two stop valves need to be installed at both ends of the water meter to facilitate the replacement of the water meter. The water passage area of the expansion device (expansion pipe, filter tank and filter screen) installed at the front end of the water meter inlet should be 1 to 2 times the diameter of the water meter section, so as to facilitate regular inspection, replacement or cleaning.
