Description :

　　Integrated DN350 electromagnetic flowmeter, split type DN350 electromagnetic flowmeter

　　1. Overview:

　　This product can measure the flow rate of dirty media, corrosive media, and suspended liquid-solid two-phase flow. This is because there are no flow obstructing components inside the instrument measuring tube, and only the inner lining and electrodes of the measuring tube are in contact with the measured fluid. The material can be selected according to the properties of the measured fluid. For example, using polytetrafluoroethylene or polytetrafluoroethylene as lining can measure various corrosive media such as acids, alkalis, salts, etc; The use of wear-resistant rubber as an inner lining is particularly suitable for measuring liquid-solid two-phase flows such as slurry and cement slurry with solid particles and high wear, as well as various suspended liquids such as fibrous liquids and pulp.

　　2、 Characteristics:

　　1. The range of electromagnetic flowmeter is wide.

　　2. In addition to measuring the volumetric flow rate of general conductive liquids, electromagnetic flow meters can also be used to measure strongly corrosive liquids such as strong acids and alkalis, as well as slurries, slurries, and pulp.

　　3. A bidirectional measurement system that can measure both forward and reverse flow rates.

　　4. The measurement results of electromagnetic flowmeter are independent of physical parameters such as pressure, temperature, density, viscosity, conductivity, and are not affected by the environment.

　　5. Electromagnetic flowmeter has reliable performance, high accuracy, low power consumption, stable zero point, and convenient parameter setting. Click on the Chinese display LCD to show accumulated flow, instantaneous flow, flow rate, flow percentage, etc.

　　4、 Installation:

　　1. The accuracy level and function of the instrument are selected based on measurement requirements and usage scenarios to achieve cost-effectiveness. For example, in situations such as trade settlement, product handover, and energy measurement, higher accuracy levels such as 1.0, 0.5, or higher should be selected; For process control applications, choose different accuracy levels according to control requirements; In some cases where only the process flow rate needs to be detected without precise control and measurement, a slightly lower accuracy level can be chosen, such as 1.5, 2.5, or even 4.0,.

　　2. When measuring medium flow rate, instrument range, and caliber, the full flow rate of the flowmeter can be selected within the range of 0.5-12m/s for measuring medium flow rate, which is relatively wide. The selection of instrument specifications (caliber) may not necessarily be the same as the process pipeline, and should be determined based on whether the measured flow range is within the flow rate range. That is, when the pipeline flow rate is too low to meet the requirements of the flow instrument or the measurement accuracy cannot be guaranteed at this flow rate, the instrument port diameter needs to be reduced to increase the flow rate inside the pipeline and obtain satisfactory measurement results.

　　3. Try to avoid ferromagnetic objects and equipment with strong electromagnetic fields as much as possible to prevent the magnetic field from affecting the working magnetic field and flow signal of the sensor.

　　4. There should be ample space around the flowmeter for easy detection and maintenance.
