technical data
This manual will assist you in installing, using and maintaining your flow meter. It is your responsibility to make sure that all
operators have access to adequate instructions about safe operating and maintenance procedures.
Main Power
120-240VAC 50Hz - 60Hz / 24-36VDC
Power Consumption
<15W (and set with sensor supporting power consumption)
Display and Push Buttons
English and Chinese display can display the instantaneous flow, total flow and percentage of flow as well as
alarm display, four soft-touch buttons, which are used for data set.
Accumulator
Forward total quantity, reverse total quantity
Output Signal
Analog output
Bi-directional, isolation 0-10mA / 4-20mA
Frequency
output
Forward and reverse flow output with frequency range set between 1 - 5000Hz. The external
voltage must be lower than 35V and the max output current is 50mA when the transistor is
turned on.
Alarm output
Two outputs from the collectors of photoelectric isolate transistors are for alarm signals.
The external voltage must be lower than 35V and the max output current is 250mA when
the transistor is turned on. Alarm status: Activates when the measured pipes are empty, the
excitation circuits are broken, or the volume of flow rate exceeds the value designed limits.
Pulse output
For pulse output in forward and reverse flow measurement, upper frequency of pulse output
can be up to 5000 CP/S relevant value of pulse is from 0.0001 to 1.0 M3/P. The width of
pulse can be set to 20ms or squired wave form automatically. The collector of transistor with
photoelectric is open circuited. The external voltage must be lower than 35V and maximum
output current is 250mA when the transistor is turned on.
