The BATCHtrol II Batch Controller features 8 digits of bright, 0.55 inch, LED display and can accept up to 20 kHz flow input from pulse producing flowmeters. The analog input versions accept inputs, such as 4 to 20 mA or 1 to 5V. The standard unit has two separate, 8 digit, floating decimal, “K” factors to convert the inputs to meaningful total and rate data. An optional 16 point K-factor can linearize flow from nonlinear meter outputs.
