HIGH PRESSURE/High ΔP Digital GAS Mass Flow Meters & Contro

For applications with high (differential) pressure Bronkhorst High-Tech
offers a special range of EL-FLOW^® and IN-FLOW Series Thermal
Mass Flow Meters and Controllers. Patented PN400/PN700 control valves can
either be integrally or separately mounted, to measure and control gas
flows from:

Meters: from 0,2…10 ml_n/min up to 10…500 m³_n/h
Controllers: from 0,2…10 ml_n/min up to 2…100 l_n/min

"Multibus" Digital Mass Flow Meters/Controllers

In some applications there are more requirements for a modern instrument
than analog-based technology can offer. Examples of these requirements
are self-diagnostics, alarm and counter functions, digital communication
and remotely adjustable control settings. These requirements can only be
met with a digital based instrument. Therefore Bronkhorst High-Tech developed
a fieldbus based pc-board for their mass flow metering and control solutions.
The latest digital instruments offer great flexibility thanks to the "multibus"
concept, thanks to which the instruments can be equipped with on-board
interface board with DeviceNet™, PROFIBUS DP, Modbus or FLOW-BUS protocol.
