Product features
The remote transmission method can use M-bus or RS485 bus;
The minimum transmission pulse equivalent can reach 0.001 cubic meters;
When pulse sampling or switching valves, they are powered by batteries, and when communicating on the bus, they are powered by the bus (M-bus) or external power (RS485);
Ultra low power consumption design ensures a service life of over 8 years;
Adopting advanced data encoding and verification methods, high communication reliability;
The table has a unique address identifier to ensure the uniqueness and accuracy of the data;
Meet the design requirements for electromagnetic compatibility of electronic products such as EMC, ESD, EMI, etc;
Combined with the upper computer system, establish a remote automatic meter reading management system to truly achieve meter reading automation.
