Adding a preset quantity of water to a mix has long been carried out using pails or hosepipes. Not very accurate and certainly not consistent. Now, Hertfordshire company Aquameter has developed the ABACUS digital water measuring system for dispensing accurate preset quantities of water straight into mixing vessels, tanks, etc. Easy to install and simple to use, the ABACUS delivers repeatable results day in, day out, reliably and consistently. Thousands of units have been sold worldwide to a whole variety of industries where water is added to powders or granules for mixing purposes. Just dial in the batch amount required and press the start button. The unit stops the flow of water when the required quantity has been delivered – easy.
