Abstract
To regulate and monitor material concentrations, e.g., sodium chlorite or hydrogen peroxide, measuring cells are employed in which these substances are reacted to completion with another substance, e.g., sulfur dioxide, in an exothermal reaction. The resulting temperature rise is then a measure for the concentration. A simple measuring cell includes a pipe section provided at both ends with mounting devices for mounting in the delivery line conveying the reaction medium. There is mounted in this pipe section a U-shaped pipe section which is open at both ends and has a smaller diameter, and whose two arms extend into the pipe section with a larger diameter. The center section of, and parallel to, is located outside of the larger pipe and is provided with a thermal insulation, a supply line for the reacting substance, and a temperature sensor.
