  • Measuring level by weight

    Measuring level or inventory by weight provides high accuracy. The weight is not affected by ingredients that foam or settle unevenly or by changes in density or the shape of the tank. Weight is weight, regardless of percent solids, bridging, rat-holing, or whether your ingredient is conductive or sound-absorbing. Because weighing is a noncontact method of measuring level, there is no chance of ...

  • A marked improvement in the reliability of the measurement of trace moisture in gases

    Introduction Water is an important substance without which mankind cannot survive. However, it also causes problems such as residual impurity in scientific experiments and in manufacturing processes where a high-vacuum condition or a high-purity gas is required. This is because water is present in the atmosphere in large quantities and therefore can intrude readily everywhere, and can adsorb ...
