MZ-2001 online liquid concentration, specific gravity, density detector

1、 Working principle: Sound waves produce different vibration frequencies in liquid media with different specific gravity concentrations,The frequency of vibration is detected by a piezoelectric crystal, shifted and amplified by a phase shifting and amplifying circuit, and then converted into a digital signal of specific gravity concentration by a microprocessorUnder normal circumstances, liquids of different concentrations exhibit a certain mathematical relationship between their specific gravity and concentration, according to the Lagrange interpolation algorithm (y=E1x)³+E2x²+Convert E3x+E4, where x is the specific gravity, y is the percentage concentration, and E1, E2, E3, and E4 are concentration conversion coefficients, to obtain the corresponding concentration value at a certain specific gravity value.

2、 Application industry: Installed on material barrels, pipelines, storage tanks, and liquid tanks through threads, flanges, and clamps, with online monitoring such as: DMAC、NMP、 The concentration%, refractive index, temperature and other parameters of various chemical liquids such as cutting fluid, emulsion, ethylene glycol, urea, ammonia water, and alcohol cleaning solution;

3、 Functional features:

1. According to the principle of optical refraction, long-term online measurement of DMAC NMP、 The concentration, refractive index, temperature and other parameters of various chemical liquids such as cutting fluid, emulsion, ethylene glycol, urea, ammonia water, and alcohol cleaning solution do not need to be calibrated after installation;

2. Using a unique multi-point curve concentration measurement algorithm to test the concentration of various chemical liquids, compared with common two-point linear concentration measurement algorithms on the market, the multi-point curve concentration measurement algorithm has higher accuracy;

3. The instrument has a built-in temperature compensation function, which can measure the concentration of liquids at different temperatures, and can also select common liquids to measure concentration without setting any parameters;

4. The instrument comes with multiple switch signal outputs, such as concentration upper and lower limits, liquid addition and inlet pump signal contacts. Users do not need to use PLC programming for automation control. Our instrument can completely replace the work of PLC, and each part is modular. Subsequent maintenance is simple, and damaged components can be directly replaced without affecting the normal operation of other components;
