Method for continually and automatically measuring the level of a water treatment product in boiler feedwater |
| abstract |
A method to continuously measure the level of a water treatment product in boiler feedwater. The product, which includes a copolymer of acrylamide and acrylate and a copolymer of acrylic acid and sodium vinyl sulphonate, is added to the feedwater to prevent the formation of scale in the boiler tubes. The method comprises reacting a sample of the feedwater with a reagent to produce turbidity in the sample and further mixing the newly reacted sample with a portion of previously measured reacted sample. The mixture of previously measured reacted sample and newly reacted sample are then photometrically measured in a pump turbidimeter analyzer to determine the level of product in the feedwater. |
