Contrec 400 Series

Field proven in thousands of applications worldwide, the Contrec 400 Series instruments provide flexible flow and batch control solutions for a wide range of applications.

Compatible with virtually every kind of flow meter, the Contrec 400 Series range of flow computers and batch controllers can accept both frequency or analog type flow signals, including signals from differential pressure devices.

A wide range of output functions and compensation techniques are available to handle most flow applications, including liquid, gas and steam measurement.

Incorporating the latest surface mount technology and electronic, components, the new 424 batch controller and 425 flow computer have evolved to meet the ever changing needs of the process industry. Fully field programmable, the 400 Series has a range of flexibility that enables instruments to be configured on site to meet specific installation requirements.

Maintaining all the best features of the existing 400 series including:

• Large LCD display
• Simple 4 button operation
