Specifically, the second flow measuring device is an electromagnetic flow meter.
Specifically, the solid material is PVA;
PVA, i.e. Polyvinyl Alcohol, is an organic compound of the formula [ C2H4O]n, the appearance is white flaky, flocculent or powdery solid and is tasteless. Soluble in water (above 95 deg.C), slightly soluble in dimethyl sulfoxide, insoluble in gasoline, kerosene, gasoline, water, etc,Vegetable oil, benzene, toluene, dichloroethane, carbon tetrachloride, acetone, ethyl acetate, methanol, ethylene glycol, and the like. Polyvinyl alcohol is an important chemical raw material, and is used for manufacturing polyvinyl acetal, gasoline-resistant pipelines, vinylon, fabric treating agents, emulsifiers, paper coatings, adhesives, glue and the like;
the physical properties of polyvinyl alcohol are influenced by chemical structure, alcoholysis degree and polymerization degree. The main structure in the polyvinyl alcohol molecule is 1, 3-propanediol, i.e. "head-tail" structure. The polymerization degree of polyvinyl alcohol is classified into ultra-high polymerization degree (molecular weight 25-30 ten thousand), high polymerization degree (molecular weight 17-22 ten thousand), medium polymerization degree (molecular weight 12-15 ten thousand) and low polymerization degree (2.5-3.5 ten thousand). The alcoholysis degree is generally 78%, 88% and 98%. The alcoholysis degree of partial alcoholysis is generally 87-89%, and the alcoholysis degree of complete alcoholysis is 98-100%. Often, the thousand or hundred digits of the average degree of polymerization are placed in front of the polymerization, and the percentage of alcoholysis is placed in the back, e.g., 17-88, i.e., the apparent degree of polymerization is 1700 and the alcoholysis is 88%. In general, the polymerization degree increases, the viscosity of an aqueous solution increases, and the strength and solvent resistance after film formation are improved, but the solubility in water and the elongation after film formation decrease. The relative density (25 ℃/4 ℃) of the polyvinyl alcohol is 1.27-1.31 (solid) and 1.02 (10% solution), the melting point is 230 ℃, the glass transition temperature is 75-85 ℃, and the polyvinyl alcohol is heated to more than 100 ℃ in the air to slowly change color and embrittle. Heating to 160-170 ℃ for dehydration and etherification, losing solubility, and heating to 200 ℃ for decomposition. And becomes a polymer containing conjugated double bonds at more than 250 ℃.

The polyvinyl alcohol is dissolved by adding the materials into room temperature water under stirring, uniformly dispersing, and then heating to accelerate dissolution, so as to prevent agglomeration and influence the dissolution speed;
the aqueous solution (5%) of polyvinyl alcohol is sensitive to borax and boric acid, and is easy to cause gelation, and when the mass of borax reaches 1% of the solution, irreversible gelation is generated. Chromates, dichromates, permanganates can also gel polyvinyl alcohols. The aqueous solution of PVA 17-88 showed a gradual increase in viscosity at room temperature over time, but the viscosity at a concentration of 8% was absolutely stable regardless of time. Polyvinyl alcohol has good film forming properties and is highly uncomfortable with many gases other than water vapor and ammonia. The light resistance is good and is not influenced by illumination. When open fire is applied, the material can burn and has special smell. Aqueous solutions sometimes exhibit toxic effects when stored. It is non-toxic and non-irritating to human skin.
