The Alcohol Monitor determines the alcohol content of your alcohol/water mixtures in the range from 0 to 100 % (v/v,w/w) at 0 °C to 40 °C. The alcohol content can be given as %v/v or %w/w. It consists of Density Transducer DPRn 427 (I) and mPDS 1100 (I) or mPDS 5 Evaluation Unit. The Alcohol Monitor is highly accurate, drift-free and requires no maintenance. Anton Paar's oscillating U-tube method is the the most accurate method for online density measurement. The Alcohol Monitor is installed either in a bypass or directly in the main line using an online fitting. Alcohol Monitor provides 1 analog input and 2 analog outputs for PLC connections
