It can also record the running status of the meter, and display the running status of the meter under the system management software through a microcomputer.
Conditions of Use:
Water temperature: 0～40℃
Water pressure: no more than 1Mpa
Indication error limit:
a. From including the minimum flow (qmin) to the low zone not including the boundary flow (qt): ±5%.
b. Never include the boundary flow (qt) to include the high area of the overload flow (qs): ±2%
It can also record the running status of the meter, display the running status of the meter under the system management software through a microcomputer, implement effective monitoring, change the unfavorable situation of arrears of water charges, meter reading at home, and save manpower for the property or water supply department.
