Guide to Selecting the OMF Series Electromagnetic Flowmeter by Kaifeng Oasis Instrument Co., Ltd.

When considering a reliable and efficient electromagnetic flowmeter, the OMF Series Electromagnetic Flowmeters from Kaifeng Oasis Instrument Co., Ltd. are a trusted choice. To ensure optimal performance and suitability for your application, follow these guidelines for selection and use:

1. Define Your Measurement Requirements

Before selecting a flowmeter, clearly outline your specific needs:

Measured Medium: The type of liquid to be measured.

Flow Rate (m³/h): Minimum, working, and maximum flow rates.

Medium Temperature (°C) and Pressure (MPa).

Installation Type: Choose inline type or insertion types based on your system design.

2. Verify Prerequisites for the OMF Series

The measured medium must be a conductive liquid with the required minimum conductivity of 5μS.

Avoid using the OMF Series with media containing excessive ferromagnetic particles or large quantities of air bubbles.

3. Understand the Measurement Principle

The OMF Series operates on Faraday’s Law of Electromagnetic Induction. As the conductive liquid flows through a magnetic field, it generates a voltage proportional to the flow velocity. This signal is captured by electrodes and processed by the transmitter to provide accurate flow measurements.

4. Key Features of the OMF Series Electromagnetic Flowmeters

No pressure loss and exceptional resistance to clogging, making it ideal for slurry applications.

Low straight pipe length requirements.

Reliable performance due to low-frequency square wave excitation, immune to power frequency and onsite interference.

Aluminum and stainless-steel transmitter housing with corrosion-resistant lining options.

Easy parameter setup with smart chip-enabled onsite display converters.

Self-diagnosing capabilities for transmitter and preset factory calibration values, easy maintenance.

Wide measurement range, supporting flow velocities from 0.1 m/s to 12 m/s.

Insertion-type models allow installation and removal without stopping the flow.

Broad application across industries like chemical, metallurgy, paper, food, oil, and municipal water supply.

5. Model Selection Guidelines

Inline or Insertion Type: Choose based on installation requirements and pipe diameters.

Display Options: For control room monitoring, opt for split models.

For onsite observation, select compact models with onsite display.

For pipe diameters exceeding 200mm or for non-stop installation/removal, consider the insertion-type OMF Series models.

6. Selecting Sensor Diameter

Match the sensor diameter with the pipeline diameter for easy installation if the flow velocity is within 0.3 m/s to 10 m/s.

For low flow velocity, consider a sensor with a smaller diameter than the pipeline, using reducers as needed.

7. Choosing Lining and Electrode Materials

Lining Material: Select based on the medium’s corrosiveness, abrasiveness, and temperature.

Electrode Material: Choose according to the medium’s chemical properties, referencing corrosion resistance data provided by Kaifeng Oasis Instrument Co., Ltd.

8. Protection Grade Selection

For underground installations prone to submersion, select submersible models, that is IP68 protection.

For above-ground installations, splash-proof models are recommended. Both IP65 and IP67 models are available.
