Features of hydrochloric acid flowmeter 1. The measurement is not affected by changes in fluid density, viscosity, temperature, pressure and conductivity. 2. There are no obstructing flow parts in the measuring tube, no pressure loss, and lower requirements for straight pipe sections. 3. The nominal diameter of the series is DN15～DN3000. Sensor liner and electrode materials are available in a variety of options. 4. The converter adopts a novel excitation method, with low power consumption, stable zero point and high accuracy. The flow range can reach 1500: 1. 5. The converter can be integrated with the sensor or separated. 6. The converter adopts 16-bit high-performance microprocessor, 2x16LCD display, convenient parameter setting and reliable programming. 7. The flowmeter is a two-way measurement system with three built-in totalizers: forward total, reverse total and difference total; it can be displayed. Zhuang, reverse flow, and has a variety of outputs: current, pulse, digital communication, HART. 8. The converter adopts surface mount technology SMT, with self-test and self-diagnosis functions. Second, several working modes of hydrochloric acid flowmeter 1. DC excitation The DC excitation method uses direct current or uses a magnet to generate a constant and uniform magnetic field. The biggest advantage of this DC excitation transmitter is that it is little affected by the interference of the AC electromagnetic field, so the influence of the self-inductance phenomenon in the liquid can be ignored. However, the use of a DC magnetic field is easy to polarize the electrolyte liquid passing through the measuring pipe, that is, the electrolyte is electrolyzed in the electric field to generate positive and negative ions. Negative electrodes are respectively surrounded by ions of opposite polarity, which seriously affects the normal operation of the instrument. Therefore, DC excitation is generally only used to measure non-electrolyte liquids, such as liquid metal flow. 2. Most of the electromagnetic flowmeters used in the AC excitation industry use the AC excitation method of the power frequency power supply to generate an alternating magnetic field, which avoids the polarization interference on the surface of the DC excitation electrode. But using AC excitation will bring a series of electromagnetic interference problems. AC excitation is now being replaced by low frequency square wave excitation. 3. Low-frequency square wave excitation The low-frequency square wave excitation waveform has two values, two-value and three-value, and its frequency is usually 1/2~1/32 of the power frequency. The low-frequency square wave excitation can avoid the orthogonal electromagnetic interference of the AC magnetic field, eliminate the power frequency interference caused by the distributed capacitance, suppress the eddy current caused by the AC magnetic field in the tube wall and inside the fluid, and eliminate the polarization phenomenon of the DC excitation. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'How Hydrochloric Acid Flow Meters Work'
