Contrec 214D ATEX Batch Controller is suitable and perfectly suit for low flow applications which require precise control of batch quantities. Batch Total, Accumulated Total and Preset values can all be displayed on the large LCD display.
For hazardous area applications, Contrec 214Di is an intrinsically safe version with both ATEX approval, and CSA approval covering both the USA and Canada. Contrec 214D ATEX Batch Controller has an input conditioning circuit which will accept pulse or frequency flow signals generated by the turbine, positive displacement, paddlewheel or other flowmeters. Control single or two-stage with Contrec 214D. This is because the unit comes with two solid-state relays, therefore, the batch controller can control two-stage with slow stop/slow start.
Contrec 214D will operate from an external power source between 9 and 28 Volts and draws no more than 4mA. Lithium batteries provide backup if the DC power is interrupted so that totals are not lost. The housing for Contrec 214D ATEX Batch Controller is housing with IP67 (Nema 4X) polycarbonate enclosure, therefore, the batch controller is completely watertight.
The Batch Controller comes with a standard wall mount bracket. Alternatively, pipe mounting bracket is also available to mount in rear or bottom. The pipe mounting stems are for mounting the Contrec 214D directly to turbine flowmeters.
