High Power Volume Lora Smart Water Meter With The Complete Software Solution

The accuracy of measurement and the reliability of communication are the most basic requirements of the wireless meter reading system, but at the same time they are not easy to solve. Because wireless communication is easily shielded by some metals, house structures, and some radio waves with similar frequencies of wireless signals.

Brief introduction

1. The power supply problem of wireless remote water meters: Since most wireless remote water meters are powered by batteries, the power consumption requirements are very strict, and it is unrealistic to replace the batteries frequently. Generally speaking, after the nominal capacity of the battery is estimated conservatively, the actual service life is still more than 6 years to meet the relevant requirements.

2. The accuracy of measurement and the reliability of communication: The accuracy of measurement and the reliability of communication are the most basic requirements of the wireless meter reading system, but at the same time they are not easy to solve. Because wireless communication is easily shielded by some metals, house structures, and some radio waves with similar frequencies of wireless signals.

3. Communication data security: The frequency band channel of wireless communication is relatively fixed, and it is easy to be detected, which requires strengthening preventive measures in terms of data security.

4. Cost of wireless remote water meters: Compared with ordinary mechanical water meters, the price of wireless remote water meters having many functions is that their cost is much higher than that of ordinary mechanical water meters. Because the cost topic is more sensitive, whether it is ordinary users or water companies, etc. Big watch users will pay attention to it. The cost here includes two parts, namely: the cost of one-time modification or installation, the operating cost of the system and the later maintenance cost.
