RS485 Communication Thread Photoelectric Direct Reading (Cold/Hot Water) Water Meter
RS485 communication thread photoelectric direct reading water meter (cold water/hot water) is a RS485 remote transmission water meter in the form of threaded connection. When threaded connection is adopted, there is no need to cut threads on the connected parts, nor is it limited by the material of the connected parts, the structure is simple, and the assembly and disassembly are convenient. This metering product is suitable for factories, communities, parks, industrial areas, and other scenarios. Solve the long-term workload of using mechanical water meters, which can not only remotely read meters, but also valve-controlled prepaid, simple, and practical. Next, I will introduce this product to all netizens and friends.
485 communication thread photoelectric direct reading water meter can measure cold water, hot water, and reclaimed water, it is not a simple measuring instrument. It is of great significance to the water supply sector (such as properties, water plants, water companies, water stations) and users. First, in terms of meter reading, the water supply department does not need to send someone to check the meter, which reduces labor costs. The user also avoids the trouble of on-site meter reading and is not disturbed. Secondly, in terms of charging, users need to pay money before using water. When the water volume reaches a certain set value, the water supply will be stopped, and they need to buy water again to use it.
The photoelectric direct reading water meter is a wired transmission method, and RS485 communication is one of the commonly used transmission methods. The rotor type water meter is used as the base meter, and the photoelectric direct reading module is adopted. The RS485-MODBUS bus is a four-wire system with strict line sequence, two power lines and two signal lines. It is convenient for installation and maintenance. The water meter does not need power supply at ordinary times, but the meter reading command is issued by the concentrator at the moment of meter reading to perform instantaneous power supply meter reading.
