Products

Liquid alkali flowmeter, also known as electromagnetic flowmeter is a high-precision, high-reliability and long service life of the flow meter, so in the design of the product structure, selection of materials, the development of technology, production, assembly and factory testing process in each of the links we are very careful to pay attention to, we also designed a set of their own **** advanced, dedicated to the production of electromagnetic flowmeter equipment and flow flow of the actual flow of the calibration device, so that both software and hardware can effectively guarantee the long-term high quality of the product. On both software and hardware can effectively guarantee the long-term high quality of the product.

Electromagnetic flowmeter specially designed with backlit wide-temperature Chinese liquid crystal display, fully functional and practical, intuitive display, easy to operate and use, can reduce the inconvenience caused by other electromagnetic flowmeter English menu. In addition, we design 4-6 multi-electrode structure, to further ensure the accuracy of the measurement and at any time without grounding ring, reducing the volume of the instrument and the installation and maintenance of the trouble.

Intelligent electromagnetic flowmeter performance characteristics.

◆Measurement accuracy is not affected by changes in fluid density, viscosity, temperature, pressure and conductivity, and the sensor induced voltage signal is linearly related to the average flow rate, so the measurement accuracy is high.

◆There is no resistance to flow in the measuring pipe, so there is no additional pressure loss; there is no moving part in the measuring pipe, so the sensor life is extremely long.

◆ Since the induced voltage signal is formed in the whole space filled with magnetic field, which is the average value on the pipe-loaded surface, the straight pipe section required for the sensor is shorter, with a length of 5 times the diameter of the pipe.

◆ Only the liner and electrode of the sensor part are in contact with the measured liquid, so as long as the electrode and liner materials are reasonably selected, they can be corrosion and wear resistant.

◆LDE converter adopts new type of microcontroller (MCU) and surface mount technology (SMT), which has reliable performance, high precision, low power consumption, stable zero point and convenient parameter setting. Click on the Chinese display LCD, display cumulative flow rate, instantaneous flow rate, flow rate, flow rate percentage and so on.

◆Bidirectional measurement system, can measure forward flow, reverse flow. Adopt special production process and high quality materials to ensure the performance of the product in a long time to maintain stability

Electromagnetic flowmeter advantages and disadvantages comparison table

Electromagnetic flow meter
	vantage	drawbacks
1	There are no moving parts and no throttling parts in the measuring tube to impede the flow of fluid, which does not cause any additional pressure loss when the fluid passes through the meter.	It can only measure the liquid flow of conductive media, not the flow of non-conductive media
2	Electromagnetic flow meters can be used to measure the flow of other electrically conductive liquids after calibration with water only.	Cannot be used to measure gases, vapors, or liquids containing large quantities of gases.
3	Their range ratios can be up to 20:1, and some even up to 100:1 range ratios.	The medium in the pipe must be full, and cannot be measured out of a full pipe.
4	No mechanical inertia, sensitive response, can measure instantaneous pulsating flow, positive and negative direction of flow	Can only be measured above DN10 pipe, not applicable to small diameter
5	Measure the flow of corrosive media, spoiled media and suspended liquid-solid two-phase flow.	Cannot measure hydrofluoric acid media
