Bronkhorst presents the MASS-STREAM series of robust mass flow meters
and controllers for gases.
MASS-STREAM thermal mass flow meters operate on the basis of direct
through-flow measurement in accordance with the constant temperature anemometer
principle. Featuring a no-moving-parts design, the flow meters allow the measured
gases to pass the two stainless steel sensor probes directly without bypass. Consequently,
the gases move entirely unhindered on their flow path, making the series
particularly suitable for applications with low pressure loss as well as less
sensitivity to moisture and particulate contamination than thermal mass flow
instruments with a bypass sensor.
Key features of the MASS-STREAM thermal mass flow meters and controllers
include a robust electronics casing design with IP65 protection (dustproof and
splash waterproof); optional integrated multifunctional display available; maximum
measuring range expanded to 10,000 ln/min air equivalent (D-6390 model); and analogue
I/O signals as well as RS232 interface provided as standard. The interface with
DeviceNet, PROFIBUS DP, Modbus or FLOW-BUS protocols can be integrated.
Bronkhorst’s MASS-STREAM thermal mass flow meters and controllers find use
in gas consumption measurements, aeration and purging processes as well as natural
gas/ biogas applications.
