Product Details

KEFN Conventional Electromagnetic Flow Meter

In the metallurgical industry, it is commonly used for flow control of cooling water in continuous casting steel, continuous rolling steel, and steelmaking electric furnaces; In the process of copper smelting and wet zinc smelting in the non-ferrous metal industry, slurry flow rate is commonly used.
In the field of public utility water supply and drainage, electromagnetic flow meters are commonly used for measuring the handover of finished water and raw water from water plants; Used for flow measurement and control between processes within the water plant, such as the ratio of raw water and condensate; In the field of drainage, it is applied to the billing and measurement of sewage received by sewage treatment plants and the discharge of sewage from various enterprises to the natural world, as well as flow measurement and control in the process of sewage treatment.
In the pulp process of the paper industry, electromagnetic flow meters are involved in measuring the flow rates of polishing pulp, water, acid, and alkali; Used in the papermaking workshop to measure the inflow and outflow of various pulp tanks and participate in various pulp proportioning processes; Used for measuring and controlling additives, dispersants, and whitening agents in the bleaching section.
In the coal industry, measuring coal washing and pipeline hydraulic transportation of coal water slurry.
In terms of food and beverage, measurement of beer and beverage filling.
In the pharmaceutical industry, the measurement of medicinal liquids during the production process.
In the chemical and petrochemical industries, it is used to measure corrosive liquids such as acids and alkalis.

There are no movable parts inside the measuring tube, making it easy to maintain and manage, so the sensor has a long service life; No obstruction components, therefore no pressure loss.
The conductivity of the tested liquid should be ≥ 5 µ S/cm. When combined with various electrodes and lining materials, it can achieve good corrosion resistance and wear resistance. It is suitable for measuring the flow rate of various acid, alkali, salt solutions, mud, slurry, pulp and other media.
The accuracy is relatively high, usually ± 0.5%. Having non-linear correction of instrument coefficients can further improve measurement accuracy.
The measurement range of the sensor is extremely wide, as it is only proportional to the average flow velocity of the measured medium and independent of the flow state (laminar or turbulent) under axisymmetric distribution.
Equipped with an N-type converter and LCD backlight display, the parameters can be modified online, and the operation is simple and convenient.
Intrinsic safety and explosion-proof types are optional.
Bidirectional measurement.
