Doğrudan Okuma sıvı Yalıtımlı Soğuk Su Tablosu - Dikey

Product introduction 
 
The digital distance transmission of data is realized by direct reading of patent technology. 
 
The longest run over six years, effectively read more than 300,000 times; 
 
The whole sealing waterproof treatment, the protection grade IP68, can be used in the submerged environment for 12 years. 
 
Characteristics of liquid seal water meter: 
 
1. Small initial flow (can be the water-saving type, 2L/h), which can improve the recovery rate of water charge; 
 
2. High accuracy, long life and accurate measurement; 
 
3. The counter gear is soaked in liquid to reduce wear; 
 
4. "demagnetization" hidden trouble of dry water meter;

The performance parameters 
 
The maximum allowable error 
 
1. The maximum allowable error in the low area, including the minimum flow rate, excluding the boundary flow, is plus or minus 5%. 
 
2. The maximum allowable error in the high area including the boundary flow rate including the overload flow is plus or minus 2% (cold water meter) or plus or minus 3% (hot water meter). 
 
Error: less than or equal to 1 (minimum display score). 
 
Electromagnetic compatibility performance 
 
1. Static discharge anti-interference degree -- level 3. 
 
2. Radiofrequency electromagnetic field radiation anti-interference degree -- level 2. 
 
The type of interface 
 
1. The rs-485 - interface follows the rs-485 communication standard and the four-wire system. 
 
2. M-bus type - interface obeys Meter - BUS communication standard, two-wire system. 
 
. Communication parameters 
 
1. Baud rate: 2400bps (optional 1200, 4800, 9600) 
 
2. Check mode: even check (optional) 
 
3. Data position: 8 bits 
 
4. Stop position: 1 bit 
 
Address: see the dial label. 
 
Communication protocol: following the technical conditions of household meter data transmission in the urban construction industry standard of the People's Republic of China.
