Basket strainer is a closed vessel with cleanable screen element designed to remove and retain foreign particles down to 0.001 inch diameter from various flowing fluids. Strainers do not necessarily remove only dirt. They take out material, which is not wanted in the fluid, and this can sometime be a valuable product, which may be saved. Basket strainers remove unwanted particles from pipeline flow.

Batch Controller is a module of the control system, which is used for controlling discontinuous or nonstandard process. It contains the hardware necessary to receive analogue, digital and counter inputs from field devices, perform control computations according to the assigned algorithm and control sequences. It provides the resulting analogue and digital outputs to the field devices.

Batch Controllers is a module of the control system which is used for controlling discontinuous or nonstandard process. It contains the hardware necessary to receive analogue, digital and counteer inputs from field devices. It has the capability of handling up to 32 analogue inputs, 72 analogue outputs, 256 digital inputs, 128 digital outputs, and 64 counter inputs. It contains PROM resident diagnostic programs.
