A vortex steam flow meter is a device used to measure the flow rate of steam or other fluids in a pipe. It works by measuring the frequency of vortices created by the fluid as it passes through a bluff body in the pipe. The vortex steam flow meter is particularly useful for measuring the flow of steam in power generation plants, where accurate flow measurement is crucial for efficiency and energy savings.
The MIK-LUGB vortex steam flow meter consists of a sensor and a transmitter. The sensor has a bluff body that is placed in the pipe, causing vortices to form downstream of the body. These vortices create pressure fluctuations that are detected by a piezoelectric crystal in the sensor. The transmitter converts the piezoelectric signal into a flow rate measurement that can be used for process control.
The vortex steam flow meter is widely used in power generation plants, where it is used to optimize steam flow and energy consumption. It is also commonly used in other industrial applications such as chemical processing, oil and gas, and food and beverage production. It has several advantages over other flow measurement technologies, including high accuracy, low maintenance, and the ability to measure flows in high-temperature and pressure environments.
In summary, the vortex steam flow meter is a highly reliable and accurate device for measuring the flow rate of steam and other fluids in a pipe. Its versatility and ease of use make it a popular choice in a range of industrial applications where precise flow measurement is essential for process control and optimization.
1. What is the MIK-LUGB vortex flowmeter with temperature and pressure compensation?
The MIK-LUGB with temperature and pressure compensation is a vortex flowmeter for steam, gases and low-viscosity liquids. It is based on the Karman vortex street and Strouhal principle, and uses temperature and pressure compensation to account for density changes in steam and gas.
2. How does the MIK-LUGB work?
The sensor has a bluff body placed in the pipe. As fluid flows past it, vortices form downstream and create pressure fluctuations. A piezoelectric crystal in the sensor detects these fluctuations, whose frequency is proportional to the flow velocity. The transmitter converts the piezoelectric signal into a flow rate for process control.
3. What are the main components?
The MIK-LUGB consists of a sensor and a transmitter. The sensor contains the bluff body and the piezoelectric detector; the transmitter processes the signal, applies temperature and pressure compensation, displays the result and provides outputs.
4. What does temperature and pressure compensation do?
The density of steam and gas changes with temperature and pressure. A vortex flowmeter measures volume flow at operating conditions; with temperature and pressure compensation, the meter corrects for these changes so that the flow can be expressed as standard volume or mass flow.
5. Why is compensation important for steam measurement?
Steam is usually billed or evaluated by mass or energy, and its density varies significantly with pressure and temperature. Without compensation, changes in operating conditions lead to errors in the mass reading. Compensation helps provide more reliable data for energy management and efficiency optimization, for example in power generation plants.
6. What media can it measure?
It measures steam, gases and low-viscosity liquids. It is especially used for steam flow measurement. Please send us your medium and operating conditions for confirmation.
7. Can it be used in hazardous (explosive) areas?
No. This product is strictly prohibited from use in explosion-proof (hazardous) locations. Please tell us if your installation is in a hazardous area so we can discuss other options.
8. What pipe sizes are available?
The MIK-LUGB with compensation is available from DN10 to DN500.
9. What connection types and pressure ratings are available?
- Wafer connection: DN10–DN500 (preferred PN2.5 MPa)
- Flange connection: DN10–DN80 (preferred PN2.5 MPa); DN100–DN200 (preferred PN1.6 MPa); DN250–DN500 (preferred PN1.0 MPa)
Please tell us your working pressure if it differs from these ratings.
10. How accurate is it?
Accuracy options are 1.0% and 1.5%, depending on the configuration. Please tell us your medium and size so we can confirm the accuracy for your application.
11. What is the range ratio?
The range ratio is 8:1. The measurable range depends on the medium density and meter size; please send us your flow range for sizing.
12. What medium temperatures are available?
Four temperature versions are available: -20 °C to +150 °C, -20 °C to +260 °C, -20 °C to +320 °C, and -20 °C to +420 °C. For superheated steam, choose the version that covers your maximum steam temperature.
13. What output signals are available?
Output options include 4–20 mA, frequency output and RS485 communication (Modbus RTU).
14. What power supply options are available?
It can be powered by 24 VDC ±5% or by a 3.6 VDC lithium battery. Please confirm which outputs you need when choosing the battery option.
15. Does it have a display?
Yes. It has a 128×64 dot matrix LCD display.
16. What is the body material and protection rating?
The shell is made of stainless steel, and the ingress protection rating is IP65.
17. Compensated or uncompensated: which should I choose?
Choose the compensated version for steam and gas when temperature or pressure varies, or when you need standard volume or mass flow. If conditions are stable or only volume flow at operating conditions is needed, the MIK-LUGB without temperature and pressure compensation may be sufficient.
18. What straight pipe length does it need?
Vortex flowmeters generally need longer straight pipe runs upstream and downstream than many other flowmeter types, depending on upstream fittings such as elbows, reducers and valves. Please follow the installation manual or send us your piping layout.
19. What should I consider during installation?
- Provide sufficient straight pipe upstream and downstream.
- Avoid locations with strong pipe vibration.
- 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 make sure gaskets do not protrude into the flow.
- Do not install in hazardous (explosive) areas.
Please follow the installation manual or contact our engineers for site-specific requirements.
20. Where is it typically used?
It is widely used in power generation plants to optimize steam flow and energy consumption, and in chemical processing, oil and gas, and food and beverage production.
21. How much maintenance does it 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.
22. What information should I provide to get a quotation?
To help us select the correct model, please provide:
- Medium name and state (saturated steam, superheated steam, gas or liquid)
- Flow range (min / normal / max) and desired flow unit (mass or standard volume)
