Choose from our range of vortex flow meters to find the perfect solution for your specific needs.
1. What is the MIK-LUGB vortex flowmeter without temperature and pressure compensation?
The MIK-LUGB is a vortex flowmeter based on the Karman vortex street and Strouhal principle. It measures steam, gases and low-viscosity liquids, and is widely used for steam, compressed air, nitrogen and other gases. This version measures flow without built-in temperature and pressure compensation.
2. How does the MIK-LUGB work?
A bluff body inside the meter causes vortices to be shed alternately on each side as fluid flows past, forming a Karman vortex street. According to the Strouhal relationship, the vortex frequency is proportional to the flow velocity within the working range. The sensor detects this frequency, and the transmitter converts it into flow rate.
3. What media can the MIK-LUGB measure?
It measures steam, gases such as compressed air, nitrogen and natural gas, and low-viscosity liquids. Please send us your medium and operating conditions for confirmation.
4. What does "without temperature and pressure compensation" mean?
This version measures volume flow at operating conditions. It does not have built-in temperature and pressure sensors to correct for density changes. For gases and steam, the density changes with temperature and pressure, so the reading is not automatically converted to standard volume or mass flow.
5. Can I use the uncompensated version for steam or gas?
Yes, when the temperature and pressure are stable, or when only volume flow at operating conditions is needed. If temperature or pressure varies and you need standard volume or mass flow, for example for energy metering, choose the MIK-LUGB with temperature and pressure compensation, or apply compensation in an external flow computer.
6. What pipe sizes are available?
The MIK-LUGB is available from DN15 to DN300.
7. What connection types and pressure ratings are available?
- Wafer connection: DN15–DN300 (preferred PN2.5 MPa)
- Flange connection: DN15–DN50 (preferred PN2.5 MPa); DN65–DN200 (preferred PN1.6 MPa); DN250–DN300 (preferred PN1.0 MPa)
Please tell us your working pressure if it differs from these ratings.
8. How accurate is the MIK-LUGB?
- Gas: DN15–DN25 1.5%; DN32–DN200 1.0%; DN250–DN300 1.5%
- Liquid: DN15–DN300 1.0%
9. What is the range ratio?
The range ratio is 8:1, based on a gas density of 1.2 kg/m³ or a liquid density of 1000 kg/m³. When the medium density is different, the range ratio will change. Please send us your medium density and flow range so we can confirm the measurable range.
10. What medium temperatures are available?
Three temperature versions are available: -20 °C to +150 °C, -20 °C to +260 °C, and -20 °C to +300 °C. For steam, choose the version that covers your steam temperature.
11. What output signals are available?
Output options include 4–20 mA, frequency output and RS485 communication (Modbus RTU).
12. What power supply options are available?
The MIK-LUGB can be powered by 24 VDC ±5% or by a 3.6 VDC lithium battery. The battery option is useful where no external power is available; please confirm which outputs you need with a battery-powered version.
13. Does it have a display?
Yes. It has a 128×64 dot matrix LCD display.
14. What is the body material and protection rating?
The shell is made of stainless steel, and the ingress protection rating is IP65.
15. Should I choose wafer or flange connection?
A wafer-style meter is clamped between pipe flanges with long bolts, making it compact and lighter; it is available from DN15 to DN300. A flanged meter bolts directly to the pipeline flanges. The choice depends on your pipe size, pressure rating and piping standard. See also the MIK-LUGB wafer installation product page.
16. What straight pipe length does the MIK-LUGB need?
Vortex flowmeters are sensitive to flow disturbances and generally need longer straight pipe runs upstream and downstream than many other flowmeter types. The required length depends on upstream fittings such as elbows, reducers and valves. Please follow the installation manual or send us your piping layout.
17. What should I consider during installation?
- Provide sufficient straight pipe upstream and downstream.
- Avoid locations with strong pipe vibration.
- For liquids, make sure the pipe is always full.
- For steam, follow good practice for drainage and insulation, and select a suitable temperature version.
- Match the meter bore to the pipe inner diameter and align gaskets so they do not protrude into the flow.
Please follow the installation manual or contact our engineers for site-specific requirements.
18. How much maintenance does the MIK-LUGB need?
It has no moving parts, which reduces maintenance frequency and improves long-term reliability. Its pressure loss is relatively low, helping reduce system energy consumption.
19. Where is the MIK-LUGB typically used?
Typical applications include steam for heating and power, compressed air, nitrogen, natural gas, and air in HVAC and industrial processes, in industries such as oil and gas, chemical and water treatment.
