MIK-LDG Insertion type electromagnetic flowmeter

The MIK-LDG insertion type is an electromagnetic flowmeter with a probe that is inserted into the pipe through a 2" process connection. Based on Faraday's law of electromagnetic induction, it measures the flow of conductive liquids in large pipes from DN100 to DN2000.

A full-bore flowmeter replaces a section of pipe and measures across the entire pipe cross-section. An insertion flowmeter uses a probe mounted through a small connection on the existing pipe. For large pipes, this generally means a lighter instrument, lower cost and easier transport and installation, while a full-bore meter such as the MIK-LDG Carbon Steel Body offers higher accuracy.

No. Like all electromagnetic flowmeters, it measures only conductive liquids. It cannot measure gases, steam or non-conductive liquids such as oils.

It measures conductive liquids with a conductivity greater than 5 μS/cm, such as raw water, tap water, wastewater, cooling water and other industrial liquids.

The MIK-LDG insertion type is suitable for pipe sizes from DN100 to DN2000.

The accuracy is 1.5%. For applications that require higher accuracy, a full-bore electromagnetic flowmeter such as the MIK-LDG Carbon Steel Body (±0.5%) may be more suitable.

The maximum measurable flow velocity is 15 m/s.

The nominal pressure is 1.6 MPa.

• Probe: ABS or polyurethane
• Electrodes: SUS316L, Hastelloy B or Hastelloy C

Send us the liquid name and concentration so we can recommend a suitable combination.

A 2" thread connection is standard, and a 2" flange connection is optional.

• Medium temperature: -20 °C to +80 °C
• Ambient temperature: -20 °C to +60 °C
• Ambient humidity: 5% to 100% RH

Yes. Both integral and remote types are available. The protection class is IP65 as standard, and IP68 is optional for the remote type, which is suitable for pits and locations that may be flooded.

• Output signals: 4–20 mA and pulse
• Communication: RS485 (standard), HART (optional), GPRS/GSM (optional)

With the GPRS/GSM option, flow data can be transmitted wirelessly to a remote monitoring platform.

• AC220V (usable from 85 to 250 VAC)
• DC24V (usable from 20 to 36 VDC)
• DC12V (optional)
• 3.6 V battery power (optional)

Power consumption is less than 20 W.

Yes. The optional 3.6 V battery-powered version can be used at sites without mains power. Combined with the optional GPRS/GSM communication, it is suitable for remote monitoring points. Please tell us your required data transmission interval so we can confirm the configuration.

• Alarms: upper limit alarm and lower limit alarm
• Self-diagnosis: empty pipe alarm and excitation alarm

• Install a 2" threaded or flanged connection on the pipe.
• Insert the probe to the depth specified in the installation manual.
• Make sure the pipe is always completely full of liquid.
• Provide sufficient straight pipe upstream and downstream of the measuring point.
• Align the probe correctly with the flow direction.

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

Because the meter is inserted into an existing pipe, we need the pipe's outer diameter, wall thickness (or inner diameter) and pipe material. This information is used to set the insertion depth and configure the flow calculation.

It is commonly used on large-diameter pipelines where a full-bore meter would be heavy or costly, such as water supply mains, wastewater pipelines, cooling water systems and irrigation networks.

It has no moving parts, so routine maintenance is minimal. For liquids that may form deposits, periodic inspection and cleaning of the probe and electrodes is recommended. The empty pipe and excitation alarms help identify problems early.

To help us select the correct model, please provide:

• Liquid name and conductivity
• Pipe outer diameter, wall thickness and material
• Flow range (min / normal / max)
• Liquid temperature and working pressure
• Integral or remote type, and IP rating
• Process connection (thread or flange)
• Power supply (AC, DC or battery)
• Output and communication requirements (e.g., 4–20 mA, RS485, GPRS/GSM)
• Quantity
