MIK-LUGB Vortex flowmeter wafer installation

The MIK-LUGB wafer installation version is a vortex flowmeter with a wafer-style body that is clamped between two pipe flanges. Based on the Karman vortex street and Strouhal principle, it measures steam, gases and low-viscosity liquids in pipes from DN15 to DN300.

When fluid flows past a fixed obstruction (bluff body) at a certain velocity, vortices are generated alternately on each side. 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.

It measures steam, gases and low-viscosity liquids. Please send us your medium and operating conditions for confirmation.

A wafer-style meter has no flanges of its own. It is placed between two existing pipe flanges and held in place by long bolts that pass through both flanges. The MIK-LUGB wafer version is available from DN15 to DN300, with a preferred pressure rating of PN2.5 MPa.

A wafer-style body is generally more compact and lighter than a flanged body of the same size, which makes it easier to transport and install and often more cost-effective. It is a good choice where installation space is limited.

Choose the wafer version for compact, cost-effective installation between existing flanges within its pressure rating. If you need a flanged body or a different pressure class, see the MIK-LUGB without compensation and MIK-LUGB with temperature and pressure compensation, which are also available with flange connections.

Please tell us whether you need temperature and pressure compensation when requesting a quotation. Compensation is recommended for steam and gas when temperature or pressure varies, or when you need standard volume or mass flow.

No. This product is strictly prohibited from use in explosion-proof (hazardous) locations.

Accuracy options are 1.0% and 1.5%, depending on the medium and size. Please tell us your application so we can confirm the accuracy.

The range ratio is 8:1, based on a gas density of 1.2 kg/m³. When the medium density is different, the range ratio will change. Please send us your medium density and flow range for sizing.

Three temperature versions are available: -20 °C to +150 °C, -20 °C to +260 °C, and -20 °C to +300 °C.

Output options include 4–20 mA, frequency output and RS485 communication (Modbus RTU).

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.

Yes. It has a 128×64 dot matrix LCD display.

The shell is made of stainless steel, and the ingress protection rating is IP65.

• Center the meter between the pipe flanges so its bore aligns with the pipe bore.
• Use suitable gaskets and make sure they do not protrude into the flow path.
• Tighten the long bolts evenly.
• Provide sufficient straight pipe upstream and downstream; vortex flowmeters generally need longer straight runs than many other types.
• Avoid locations with strong pipe vibration.
• For steam, follow good practice for drainage and insulation.

Please follow the installation manual or contact our engineers for site-specific requirements.

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.

It is used for steam, compressed air, nitrogen and other gases, as well as low-viscosity liquids, in industrial pipelines where a compact installation is preferred.

To help us select the correct model, please provide:

• Medium name and state (steam, gas or liquid) and density
• Flow range (min / normal / max)
• Operating temperature and pressure
• Pipe size and flange standard
• Whether temperature and pressure compensation is required
• Output signal and power supply requirements
• Confirmation that the installation is not in a hazardous area
• Quantity
