The intelligent alternative for VA meters: mass flow

The intelligent alternative for VA meters: mass flow meters for gases with flow display
> Introduction
Bronkhorst®, specialists in low flow measurement and control,
have designed an innovative series of mass flow meters, regulators
and controllers with integrated display. The MASS-VIEW® series
provides modern, novel and economical alternative to variable area
meters (VA meters), also known as purge meters.
Unlike conventional VA meters these new flow meters measure
mass flow instead of volume flow. For easy VA meter replacement
the MASS-VIEW®’s mechanical construction offers the most
common options for process connection on the market.
> MASS-VIEW® series
thermal mass flow meters
Bronkhorst designed MASS-VIEW® series operate on the principle of
direct thermal mass flow measurement (no by-pass). An advantage
of using this type of sensor is that the instrument measures direct
mass flow, without the need of temperature and pressure correction.
Other benefits, compared to conventional VA meters are higher
accuracy, wider rangeability (up to 1:100), free of parallax errors and
an inherently safer construction, by eliminating glass components
in the flow path. MASS-VIEW® flow meters can be supplied in full
scale ranges from 0.05 up to 500 ln/min (Air equivalent), with a
pressure rating of 10 bar(g) or 150 psi(g). A bright graphical OLED
display, clearly visible at wide angles, allows reading of actual flow
(value and a bar graph), total flow and type of gas.
The display features easy set up via a user-friendly menu, using a
4-way navigation push button. The pre-installed gases eliminate
the need to recalibrate for different gases and therefore reduce
the cost of ownership. Additional features & functions include a
variety of alarm and counter functions, an analog output signal,
digital interfaces and two relay contacts. Flow control may be
achieved with an optional needle valve. These high quality needle
valves offer smooth and fine adjustment of the gas flow rates.
The latest innovation to the MASS-VIEW® product line is the addition
of an integrated auto-compensating controller. The desired flow
rate is set via the needle valve in the usual way, however, any
upstream pressure variation is now automatically compensated
to ensure a steady, constant flow.

instruments.
> Display menu
The 4-way navigation push button provides access to a userfriendly menu, e.g. for zero function, for selection of pre-installed
gases in pre-installed capacities, setting of engineering units,
alarm functions (minimum/maximum/counter limit) and counter
functions. Password protection is provided to prevent unauthorized
changes. Below overview of the MASS-VIEW® menu functions
illustrates the great versatility of this product line.
These software tools are freeware for users of our MASS-VIEW®
series and other digital Bronkhorst instruments and can be
downloaded from http://www.massflow-online.com
