HIGH PRESSURE / High ΔP
Digital GAS Mass Flow Meters & Controllers
General
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 mln/min up to 10...500 m3n/h
Controllers: from 0,2...10 mln/min up to 2...100 ln/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 DeviceNetTM, PROFIBUS DP, Modbus or FLOW-BUS
protocol. More

High Pressure Mass Flow Meters ( Series F-12x / F-13x / F-14x ) up to
100 ln/min can be close-coupled with Control Valves ( Series F-021 / F-033
/ F-043 ) to constitute a compact mass flow control assembly. Alternatively,
the following models are available with integrated Control Valve:
