  • Boiler Dissolved Oxygen Control

    DISSOLVED OXYGEN CHEMISTRY Dissolved Oxygen (DO) is a measure of the amount of oxygen, usually thought of as a gas, that is dissolved in a liquid such as water. Oxygen is essential to life and is also the most common element found taking part in corrosion reactions. DO can be thought of as the fuel needed for the corrosion process to proceed. It is the corrosion reactions that necessitate ...

  • Determination of diurnal water level fluctuations in headwaters

    The aim of this paper is to study diurnal fluctuations of the water level in streams draining headwaters and to identify the controlling factors. The fieldwork was carried out in the Gryżynka River catchment, western Poland. The water levels of three streams draining into the headwaters via a group of springs were monitored in the years 2011–2014. Changes in the water pressure and water ...

  • Total Dissolved Solids (TDS) Measurement

    Definition Total Dissolved Solids (TDS) is a measure of the sum of all inorganic and organic substances in a liquid in molecular, ionized or micro-granular colloidal suspended form. The solids must be small enough to survive filtration through a sieve the size of two micrometer.  TDS solids are normally found in all freshwater systems. Major applications of TDS are: at low levels the ...

  • Water Bottling Plant Chooses Greyline for Level Control - Case Study

    Culligan were able to double up level monitoring of two tanks with one instrument because pairs of identical-sized tanks were interconnected with a 2” pipe near their base. The Greyline SLT32 was calibrated to display the combined volume of both tanks. This function worked with a two vertical tanks as well as a pair of horizontal round tanks where the SLT32’s HRT round tank volume ...
