Measurement principle
Specifications
| Principal of measurement | Electromagnetic type with Faraday’s law of electromagnetic induction | |||
|---|---|---|---|---|
| Model (PROVISIONAL) | VNS05 | VNS10 | VNS20 | |
| Accuracy assured flow-rate range *2 | 0.05～1 L/min | 0.5～10 L/min | 3.0～60L/min | |
| Measurement starting flow-rate | 0.025 L/min | 0.25 L/min | 1.5 L/min | |
| Piping connection | Socket type union joint (16A) |
Socket type union joint (16A) |
Socket type union joint (20A) |
|
| Accuracy *3 | Unit pulse output | ±2.0%RS (100~20% of the maximum flow-rate) ±0.4%FS (20~5% of the maximum flow-rate) |
||
| Response time (at 63% response) | Standard: 2 seconds. Setting within the range of 0.1600 seconds is available. | |||
| Fluid temperature range | 0~40°C, freezing must be avoided. (VNS05 can resist 15 minutes per day of 95°C, whereas its accuracy is out of guarantee. | |||
| Measurable fluid |
For other kind of liquid, by selecting with reference to the following major materials of the fluid-touching materials, please consult with us for suitability confirmation. |
|||
| Working ambient temperature range | -20~60°C | |||
| Ambient temperature range for storage | -20~70°C | |||
| Fluid pressure range | 0~1MPa | |||
| Signal cable |
|
|||
| Display | 1 LED display at the flowsensor’s body
|
|||
| Place of installation | Indoor installation (In case of outdoor installation, please take necessary measure so that the flowsensor is not exposed to rain and sun beam directly.) |
|||
| Enclosure | IPX4 | |||
| Corresponding standard | CE Standard *1 | |||
| Fluid-touching materials | Main body: PEEK resin Electrodes: Pure titanium (2 kinds)O-ring: For sodium hypochlorite, etc. – FKM (Fluoro rubber) For Sodium hydroxide aqueous solution, etc. — EPDM (Ethylene propylene rubber) |
|||
| Installation position | Free (Vertical piping is recommended.) | |||
*1 Except EN61000-4-5(surge) because VN series is intended to utilize as the built-in flowsensor of a machine,etc.
*2 (Minimum flow-rate ~ maximum flow-rate)
*3 For constant flow without pulsation.
