MIK-LDG Stainless steel body electromagnetic flowmeter

The MIK-LDG stainless steel body electromagnetic flowmeter measures the flow of conductive liquids such as water, acids, caustic solutions and slurries. It is available in integral and split (remote) versions, with ANSI, JIS or DIN flanges.

It works on Faraday's law of electromagnetic induction. When a conductive liquid flows through the magnetic field inside the measuring tube, a voltage proportional to the flow velocity is induced. The meter measures this velocity and calculates the volume flow rate from the tube's cross-sectional area.

A stainless steel body offers better corrosion resistance than a carbon steel body, making it suitable for corrosive environments, outdoor or humid locations, and installations where a clean appearance matters. For general water and wastewater pipelines, the MIK-LDG Carbon Steel Body is a cost-effective alternative. In both cases, the liner and electrodes are the parts in contact with the liquid and must be selected according to the medium.

A stainless steel body alone does not make a meter hygienic. For food and beverage processing, see the MIK-LDG Sanitary Electromagnetic Flowmeter, which is designed for food processing applications.

It measures conductive liquids, including water, wastewater, acids, caustic solutions and slurries. It cannot measure gases, steam or non-conductive liquids such as oils.

• Theoretical minimum: 20 μS/cm for water; 5 μS/cm for other liquids
• Recommended: above 30 μS/cm

For liquids with lower conductivity, see the MIK-FMC400 Low Conductivity Electromagnetic Flow Meter.

The measurable flow velocity range is 0.2 m/s to 15 m/s. Choose a meter size so that your normal flow falls within this range.

Pipe sizes range from DN15 to DN1200, with ANSI, JIS or DIN flanges.

Accuracy is ±0.5%. When the flow velocity is below 1 m/s, the accuracy is ±0.5% ±2 mm/s.

Nominal pressure ratings range from 0.6 MPa to 4.0 MPa, depending on the pipe size and flange. Please tell us your working pressure when ordering.

Options include PFA, FEP (F46), PTFE and neoprene. As a general guide, neoprene is commonly used for water and wastewater, while PTFE, FEP and PFA are used for corrosive chemicals and higher temperatures.

Options include SUS316L stainless steel, Hastelloy C, titanium, tantalum and platinum-iridium. 316L is commonly used for water and mildly corrosive liquids; the other materials are used for more corrosive media. Send us the liquid name and concentration for a recommendation.

• Integral type: -10 °C to 80 °C
• Split type: -25 °C to 180 °C

For high-temperature liquids, the split type is recommended because the converter is installed away from the hot pipeline. The maximum temperature also depends on the liner material.

The ambient temperature range is -10 °C to 60 °C.

In the integral type, the converter is mounted directly on the sensor. In the split type, the converter is installed separately and connected to the sensor by cable. The split type supports higher medium temperatures and is suitable for locations that are hard to reach or subject to vibration. See also the MIK-LDG Remote Type Electromagnetic Flowmeter.

The standard rating is IP65. If the sensor may be submerged, for example in a pit or valve chamber, consider the MIK-LDG Remote Type, whose sensor has IP68 protection.

An electromagnetic flowmeter is a volumetric flowmeter: it measures flow velocity and calculates volume flow. If you need direct mass flow and density measurement, see our Coriolis mass flowmeters.

Power supply and output options depend on the configuration. Please tell us your available power (AC or DC) and the signals your control system requires, such as 4–20 mA, pulse or RS485, and we will confirm a suitable configuration.

The MIK-LDG is manufactured according to the JB/T 9248 standard for electromagnetic flowmeters.

• The measuring tube must always be completely full of liquid.
• Provide sufficient straight pipe upstream and downstream of the meter.
• Avoid the highest point of the pipeline; vertical pipes with upward flow are preferred.
• Ground the sensor properly for a stable signal.
• Keep away from strong magnetic fields and heavy vibration, or use the split type.

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

No. It has a full-bore design with no moving parts or throttling components, so maintenance needs and pressure loss are minimal. It also supports bidirectional flow measurement. For liquids that form deposits, periodic electrode inspection is recommended.

In order of usage, typical industries include water and wastewater, chemical, food and beverage, power, pulp and paper, metals and mining, and pharmaceuticals.
