Technical Specifications
| Main Power | AC 220 V 50 Hz or DC 24 V |
| Power Consumption | <15 W (And set with sensor supporting power consumption) |
| Display And Push Buttons | The big screen LCD display with back lighting can display the instantaneous flow, total flow and percentage of flow as well as alarm display, four thin-film touch nubs, which is used to data set. |
| Accumulator | Forward total quantity, reverse total quantity |
| Analog Output | Bi direction with two ways, Isolation 0 mA to 10 mA or 4 mA to 20 mALoad resistor: 0 mA to 10 mA; 0 KΩ to 1.5 KΩ; 4 mA to 20 mA; 0 Ω to 750 Ω |
| Frequency Output | Forward and reverse flow output with frequency range set between 1 Hz to 5000 Hz. The external voltage must be lower than 35 V and the max output and the max output current must be 50 mA 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 35 V and the max output current is 250 mA 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, the upper frequency of pulse output can be up to 5000 CP/S relevant value of pulse is from 0.0001 M3/P to 1.0 M3/P. The width of the pulse can be set to 20ms or squired wave automatically. The collector of the transistor with photoelectric is open-circuited. The external voltage must be lower than 35 V and the maximum output current is 250 mA when the transistor is turned on. |
| Accuracy | ±0.5% of the value displayed, ±0.3% or ±0.2% are selectable. |
| Damping Time Constant | Continuous variable from 0 s to 100 s (90%) can be selected by group |
| Communication | RS232, RS485 or HART Communication are selectable, with lighting resistance |
| Power Failure | An anti-failure clock is designed in the flow meter which can save the power failure records for 16 times (10 years) |
| Protection Class | IP 65 |
