Electrical performance index
Work power
A. power supply: 24VDC + 15%, for 4 ~ 20mA output , pulse output, alarm output, RS-485 etc.
B. internal power supply: 1 groups of 3.6V lithium battery (ER26500) can be used for 2 years, when the voltage is less than 3.0V, the undervoltage indication.
Power consumption of whole machine
A. external power supply: <2W
B. battery power supply: average power consumption of 1mW, can be used for more than two years
Pulse output mode
A. sensor pulse signal, pulse signal flow sensor, the isolated amplifier output, high level of more than 20V and the low level of less than 1V; frequency output, 0-5000HZ output, the corresponding instantaneous flow, this parameter can set the button
B. equivalent pulse signal, the isolated amplifier output, high level of more than 20V and the low level is less than or equal to 1V, the unit volume can be set on behalf of the pulse range: 0.0001m3~100m3. Note: select the output equivalent pulse signal frequency is less than or equal to 1000Hz;Can be matched with a valve controller made of IC card prepayment system, high level output signal amplitude is larger than 2.8V, low level amplitude less than 0.2V.
RS-485 communication (photoelectric isolation)
using RS-485 interface, can be directly connected with the host computer or the two remote display table, medium temperature, pressure and standard volume flow and standard with temperature and pressure compensation after the total volume
correlation

4 ~ 20mA standard current signal (photoelectric isolation) and the standard volume is proportional to the corresponding 4mA, 0 m3/h, 20 mA corresponding to the maximum standard volume (the value can be set at a level menu), standard: two wire or three wire, the flowmeter can automatically identify the inserted module according to the current correct and output.
Control alarm signal output
