Overview
| Model | VN 05 | VN 10 | VN 20 | |
|---|---|---|---|---|
| Flow-rate range | 0.05 to 1L/min | 0.5 to 10L/min | 3 to 60L/min | |
| Connection | R1/4" | R1/2" | R1" | |
| Accuracy | Unit pulse (L/P) | ±2.0% RS (100%~20% of tha maximum working flow-rate(Qmax)) ±0.4% FS (20%~5% of the maximum working flow-rate(Qmax)) |
||
| High-density pulse | ±2.5% RS (100%~20% of the maximum working flow-rate(Qmax)) ±0.5% FS (20%~5% of the maximum working flow-rate(Qmax)) |
|||
| Output | 2 open collector outputs*2 | |||
| Unit pulse | 0.001, 0.01, or 0.1 | 0.01, 0.1, or 1 | 0.1, 1, or 10 | |
| High density pulse | Frequency of the upper limit of the accuracy guaranteed flow-rate range can be set within the range of 20 to 400Hz. Setting step is 0.1Hz |
|||
| Warning | Outputted in case of excitation error, memory error, no-water detection, excessive fluid noise, reverse-flow detection, excessive flow-rate detection, and low power voltage detection |
|||
| Switch | Output of result of level judgment or window judgment | |||
| Fluid to be measured | Liquid which does not corrode materials that contact the liquid, Not less than electric conductivity rate 50μS/cm |
|||
| Fluid-touching materials | SUS316L, PPS resin, and Fluorine rubber | |||
| Fluid conductivity | 50μS/cm and above | |||
| Fluid temperature | 0 to 60°C (Freezing & Dew coudensation must be avoided) | |||
| Maximum working | 1 MPa at 25°C | |||
| Enclosure | IP64 | |||
| Power supply | 12-24 V DC 100mA | |||
| Installation position | Free (Entering of air should be avoided) Vertical piping or position that LED display becomes horizontal is recommended |
|||
| Sensor weight (approx.) | 200g | 200g | 300g | |
*1 Except EN61000-4-5(surge) because VN series is intended to utilize as the built-in flowsensor of a machine,etc.
*2 possible to output two of the following: Unit pulse, High-density pulse, Warning, Switch
