MIK-LWGY series liquid turbine flowmeter is a kind of speed instrument, which has the advantages of high accuracy, good repeatability, simple structure, small pressure loss and convenient maintenance. It is used to measure the volume flow of low viscosity liquid in closed pipe.
1. What is the MIK-LWGY thread connection turbine flowmeter?
The MIK-LWGY thread connection version is a liquid turbine flowmeter for small-diameter pipelines. It is a velocity-type instrument for measuring the volume flow of low-viscosity liquids in closed pipes, offering high accuracy, good repeatability, a simple structure, low pressure loss and convenient maintenance. The threaded design makes installation and maintenance simple.
2. How does the MIK-LWGY work?
Liquid flowing through the meter turns a turbine rotor at a speed proportional to the flow velocity. A pickup detects the rotating blades and produces pulses. The pulse frequency corresponds to the instantaneous flow rate, and the total pulse count corresponds to the total volume.
3. What liquids can the MIK-LWGY measure?
It measures clean, low-viscosity liquids in closed pipes. The measurement does not depend on conductivity, so it can be used for water and water-based liquids as well as low-viscosity non-conductive liquids such as light oils. Liquids containing fibers or solid particles are not recommended. Please send us your liquid details for confirmation.
4. What viscosity limit applies?
The medium viscosity should be less than 5×10⁻⁶ m²/s (5 cSt). For comparison, water at 20 °C is about 1 cSt. For liquids with viscosity above 5×10⁻⁶ m²/s, the flowmeter needs to be calibrated with the actual liquid before use. Please tell us the viscosity at your operating temperature.
5. What pipe sizes and thread types are available?
- Male thread: DN4–DN100
- Female thread: DN15–DN50
The threaded version is usually used for small-diameter flow measurement.
6. How accurate is the MIK-LWGY?
Accuracy options are 0.5%R and 1.0%R, where %R means percent of reading.
7. What flow range does each size cover?
The flow range depends on the meter size. Please send us your minimum, normal and maximum flow rates, and our engineers will select a size whose range covers your application.
8. What medium temperature can it handle?
The medium temperature range is -20 °C to +120 °C.
9. What working pressure and thread standards are available?
Please tell us your working pressure and the thread standard used in your piping (for example BSP or NPT), and our team will confirm a suitable configuration.
10. What power supply options are available?
- 3.6 V lithium battery
- 220 VAC
- 24 VDC
The battery option is useful where no external power is available. Please confirm which output signals you need, as the available outputs may depend on the power supply option.
11. What output signals are available?
Output options include pulse, 4–20 mA, Modbus and HART, allowing connection to PLC, DCS, SCADA and batching controllers.
12. What is the ingress protection rating?
IP65 is standard. IP67 and IP68 are available on request.
13. Should I choose the thread or flange connection version?
14. Can the MIK-LWGY measure gas?
No. The MIK-LWGY is a liquid turbine flowmeter. For gas or steam measurement, consider our vortex flowmeters.
15. Do I need a filter before the meter?
Particles can damage the rotor and bearings, so a filter or strainer is generally recommended upstream of the meter, especially if the liquid may contain debris.
16. What should I consider during installation?
- Install the meter with the flow direction arrow matching the actual flow.
- Provide sufficient straight pipe upstream and downstream of the meter.
- Keep the pipe full of liquid and free of air bubbles.
- Install a filter upstream when the liquid may contain particles.
- Avoid strong vibration and strong magnetic fields near the pickup.
Please follow the installation manual or contact our engineers for site-specific requirements.
17. How much maintenance does the MIK-LWGY need?
It has a simple structure and is easy to maintain. Because the rotor and bearings are moving parts, periodic inspection is recommended, especially for liquids that may contain particles.
18. Turbine or electromagnetic flowmeter: which should I choose?
A turbine flowmeter suits clean, low-viscosity liquids, including non-conductive ones. An electromagnetic flowmeter suits conductive liquids, including dirty water and slurries, and has no moving parts.
19. Which industries use the MIK-LWGY?
It is widely used in petroleum, chemical, metallurgy, water supply and papermaking industries.
20. What information should I provide to get a quotation?
