This article is aimed at comparing the effectiveness of testing the dimensional parameters of a tank wagon with an internal ribbing with a nominal volume of 85 m3 in a production plant. One of the used methods is the traditional volumetric method, ie measuring the volume of water with a pair of flowmeters when filling the vessel. The second method is a method of computer processing of data obtained by 3d scanning of the interior of the tank from several positions and the subsequent composition of the tank model and calculation of its volume using the PolyWorks program. Evaluation of both measurement methods revealed that despite the non-trivial internal division of the measured object, both methods are sufficiently accurate, and even in this case the scanning method provides the measurement result several times faster compared to the volumetric method. In the reported example, measurement time spent to achieve results for the scanning method was approximately one third comparing with that of the water filling.

1. A volumetric method for the determination of sodium which can be separated as a triple salt (uranium zinc sodium acetate) from mixed solutions is described. The reduction of the uranium with titanous chloride, upon which it depends is shown to be quantitative.2. Calcium, magnesium, and relatively large proportions of potash do not interfere. The procedure for the removal of iron, aluminium and phosphates by gentle ignition is simple and obviates the risk of error by the introduction of sodium as an impurity in the chemical reagents necessary for precipitation methods.3. 0.1 mg. of sodium can be determined accurately.

Abstract A collaborative study was conducted to compare a spectrophotometric molybdovanadate method and the official gravimetric quinoline molybdate fertilizer method 2.025(b), slightly modified, with the official volumetric method 20.032. Six collaborating laboratories analyzed dilute acid solutions of the ash of 5 different kinds of fruit products and an aqueous solution containing only KH2PO4 by each of the 3 methods. Satisfactory agreement between laboratories and good agreement between methods were obtained. From the results of this collaborative study it appears that the quinoline molybdate and the molybdovanadate methods are more accurate and precise than the official volumetric method. It is recommended that both the spectrophotometric molybdovanadate method and the gravimetric quinoline molybdate method for the determination of phosphorus in fruits and fruit products be adopted as official first action.
