Passive photoelectric direct reading sampling

◆Protection level: 1P68, copper-sealed counter
◆Accurate reading: infrared beam sampling, real-time reading value is completely consistent with the mechanical indication value
◆Interface type: RS-485 type, four-wire system; M-BUS type, two-wire system
◆ Working power supply: DC12V, needs to be powered by external equipment
◆Communication protocol: CJ/T188, DL/T645, MODBUS, etc.
