About Pump Controllers

Pump controllers monitor flow and/or level variables, and control a pump accordingly to maintain the desired levels. Pump control can include simply turning a pump on and off, or more advanced controls for pump speed, output pressure, etc. Many pump controllers include rate indication features and totalizer, data logger, and chart recorder capabilities. Products that provide level or pressure control are also available. Level controllers monitor, regulate, and control liquid or solid levels in a process. Pressure controllers accept inputs from pressure sensors, transmitters, gauges, and other devices. These pump controllers then adjust and control the pressure to maintain or achieve a desired level.   Some pump controllers are printed circuit boards (PCB) that can be plugged directly into a computer backplane. Others attach to a panel or bolt onto a chassis, wall, cabinet, or enclosure; mount in racks and include hardware such as rail guides, flanges, or tabs; or mount on a standard DIN rail. Benchtop or floor-standing pump controllers with a full casing or cabinet and an integral interface are also available.

Specifications for pump controllers include number of inputs, number of outputs, input types, output types, and number of zones (if applicable). The number of inputs equals the total number of signals sent to the controller. The number of outputs equals the total number of outputs used to control, compensate or correct the process. Input types include: direct current (DC) voltages, current loops, analog signals from resistors or potentiometers, frequency inputs, and switch or relay inputs. Output types include analog voltages, current loops, switch or relay outputs, and pulses or frequencies. Pump controllers can also send inputs or receive outputs in serial, parallel, Ethernet or other digital formats which indicate a process variable. Some pump controllers send or receive accept commands and inputs from information converted to an industrial fieldbus protocol such as CANbus, PROFIBUS®, or SERCOS, or other industrial automation protocol. PROFIBUS is a registered trademark of PROFIBUS International.
