1. What is the MIK-FVM200 micro vortex flow meter?
The MIK-FVM200 is a compact vortex flow meter for small pipes from DN8 to DN15. It monitors both the flow and the temperature of liquids in real time, shows both values on an OLED display, and provides analog or RS485 outputs plus an alarm switch output.
2. How does the MIK-FVM200 work?
A bluff body in the flow channel generates alternating vortices as liquid flows past. The vortex frequency is proportional to the flow velocity within the working range. The sensor detects this frequency, and the electronics convert it into flow rate. Because there are no rotating parts in the flow path, the design is simple and easy to maintain.
3. What does the MIK-FVM200 measure?
It directly measures flow rate and temperature, so one device can monitor both at the same measuring point.
4. What liquids can it measure?
It measures water and water-soluble liquids such as ethylene glycol. Please send us your liquid details for confirmation.
5. Can the MIK-FVM200 measure gas, steam or oil?
6. What sizes and flow ranges are available?
- DN8: 1–15 L/min
- DN10: 3–30 L/min
- DN15: 5–50 L/min
7. How accurate is the MIK-FVM200?
- Flow: ±3%
- Temperature: ±1 °C
8. What temperature range does it support?
The temperature range is 0 °C to 90 °C.
9. What is the maximum process pressure?
The maximum process pressure is 1.2 MPa at 40 °C. The allowable pressure may be lower at higher temperatures; please tell us your operating pressure and temperature so we can confirm suitability.
10. What power supply does it require?
The MIK-FVM200 requires a 24 VDC power supply.
11. What outputs are available?
- Flow and temperature as 4–20 mA signals, or RS485 communication (Modbus-RTU)
- Alarm switch output
Please tell us which output option you need when ordering.
12. Does it have a display?
Yes. An OLED display shows the fluid flow and temperature in real time.
13. What is the protection level?
The protection level is IP65.
14. Which industries use the MIK-FVM200?
It is widely used in petrochemical, electric power, gold mining, steel mills, paper, food processing, water treatment and battery manufacturing, for example to monitor cooling water and glycol circuits in small pipelines.
15. What should I consider during installation?
- Install the meter with the flow direction arrow matching the actual flow.
- Keep the pipe full of liquid and free of air bubbles.
- Provide sufficient straight pipe upstream and downstream of the meter.
- Avoid strong pipe vibration near the meter.
- Install a filter upstream if the liquid may contain particles.
Please follow the installation manual or contact our engineers for site-specific requirements.
16. How much maintenance does it need?
The MIK-FVM200 has a simple structure with no rotating parts in the flow path, so it is easy to install and maintain.
17. MIK-FVM200, MIK-FLM200 or MIK-FMX240: which should I choose?
- MIK-FVM200 micro vortex: water and water-based liquids such as ethylene glycol; DN8–DN15; flow and temperature; flow accuracy ±3%; no rotating parts.
- MIK-FLM200 micro turbine: water, glycol solutions and lubricants; DN10–DN25; flow and temperature; flow accuracy ±1.5%; has a rotating impeller.
- MIK-FMX240 compact electromagnetic: conductive liquids (≥2 μS/cm); DN6–DN65; accuracy ±0.5%; no moving parts; not suitable for non-conductive liquids.
