Functions
| Function | Function Description |
| Parameter Setting | Users can set parameters via three infrared keys without opening the cover |
| Display Language | Supports Chinese and English display modes |
| LCD Display | Instantaneous flow, instantaneous flow percentage, instantaneous flow progress bar, forward/reverse total, signal quality, operating status, flow velocity, time and date, etc. |
| Damping | Damping time can be set between 0.1~200s |
| Unit Setting | Supports total units m³, L, ten, kg, gal, Ib, ft³, time units s, min, h, day, flow units can be any combination of the above units |
| Pulse Output | Pulse width: 50% duty cycle, 0.05, 0.1, 1, 20, 50, 100ms Pulse equivalent: 1~1000 Pulse rate: 0.0001~10000pps |
| Communication Setting |
The communication setting function allows selection of baud rate, parity bit and data format. Baud rate: 2400, 4800, 9600 Parity: None, odd parity, even parity |
| Bidirectional Measurement | Can measure forward and reverse flow |
| Batch Filling | When the total reaches the preset value, digital output or relay output alarms |
| Preset Total Value | Parameter setting or status input function allows the total to be preset to a set value or zero |
| Alarm Selection Function | Alarms are divided into system alarms, process alarms (e.g. "empty pipe", "excitation broken"), setting alarms and warnings. Users can choose whether to alarm for each item. |
| Alarm Output | For the alarm items selected in the alarm selection function, status output is performed when a fault occurs |
| Self-diagnosis | When an alarm occurs, the alarm content will be displayed |
| Flow High/Low Alarm | When the flow is greater than or less than the set value, an alarm is generated. In addition, an upper limit value and a lower limit value can be set. When the flow is greater than the upper limit or less than the lower limit, an alarm is output |
| Signal Quality Diagnosis Function | This function allows monitoring the contamination level of electrodes and insulating materials. According to the contamination status, the status output will alarm the user. At this time, the electrodes need to be cleaned |
| Slurry Measurement Function | Set excitation frequency to 25Hz to measure slurry, coal slurry, mud, mortar, pulp and other slurries |
| Low Conductivity Measurement Function | Set excitation frequency to 25Hz to measure liquids with conductivity as low as 5μS/cm |
