Digital (fieldbus) technology

Digital = Standard

All mass flow and pressure meters/controllers are equipped with a digital pc-board, featuring self-diagnostics, alarm and counter functions, digital communication and remotely adjustable control settings. These digital flow meters, flow controllers and pressure transducers/controllers from Bronkhorst offer great flexibility thanks to the "multibus" concept, whereby the instruments can be equipped with an on-board interface with PROFIBUS DP, PROFINET, DeviceNet™, CANopen^®, FLOW-BUS, Modbus-ASCII/RTU or EtherCAT^® protocol.
