Abstract: the works of hydrochloric acid flow meter scale information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. 1 *, hydrochloric acid flow meter has the function of the characteristics. Measurement is not affected by fluid density, viscosity, temperature, pressure, and the influence of the conductivity changes. 2. Measuring pipe unimpeded flow components, no pressure loss, low straight pipe requirements. 3. The series of nominal diameter DN15 ~ DN3000. Sensing. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the hydrochloric acid flow meter scale works article details. 1 *, hydrochloric acid flow meter has the function of the characteristics. Measurement is not affected by fluid density, viscosity, temperature, pressure, and the influence of the conductivity changes. 2. Measuring pipe unimpeded flow components, no pressure loss, low straight pipe requirements. 3. The series of nominal diameter DN15 ~ DN3000. Sensor lining and electrode materials have many choices. 4. Converter adopts novel excitation method, low power consumption, zero point stability, high precision. Flow range up to 1500:1. 5. Converter can be separated and sensor of a size or type. 6. Converter adopts 16-bit high-performance microprocessors, 2 x16lcd display, parameter setting is convenient, reliable programming. 7. Flow meter to measure the size of the system, two-way within three integrator: forward, reverse the amount and total difference amount; Zhuang, reverse flow, and have a variety of output: current, pulse, digital communications, HART. 8. Converter adopts SMT surface mount technology, it has self-check and self-diagnosis function. Second, hydrochloric acid several works 1 meter. Dc excitation dc excitation method with direct current (dc) or by * magnet produces a constant homogeneous magnetic field. The dc excitation zui big advantage of the transmitter is affected by the ac electromagnetic interference is very small, so can ignore the influence of self-induction phenomenon of liquid. But using dc magnetic field is easy to make by measuring the electrolyte fluid of the pipe is polarized, the electrolyte by electrolysis in the electric field, produce positive and negative ions, in under the action of electric field force, ran to the anode, anion cation ran to the cathode, which will result in positive and negative electrodes were surrounded by ions of opposite polarity, seriously affect the normal work of the instrument. So, dc excitation only commonly used for measuring the liquid electrolyte, such as liquid metal flow, etc. 2. Ac excitation on the industrial use of electromagnetic flowmeter, mostly adopts the power supply power frequency ac excitation method to produce alternating magnetic field, to avoid the dc excitation on the surface of the electrode polarization interference. But the use of ac excitation will bring a series of electromagnetic interference problem. Ac excitation is now replaced by low frequency square wave excitation. 3. Low frequency square wave excitation frequency square wave excitation waveform has two values and three two kinds, the frequency of power frequency usually 1/2 ~ 1/32. Low frequency square wave excitation can avoid orthogonal electromagnetic interference of ac magnetic field, power frequency interference caused by distributed capacitance, inhibition of ac magnetic field within the tube wall and fluid caused by eddy current, dc excitation polarization phenomenon. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
