Page 3: Short-Form Operation Instruction
BRONKHORST® Short-form Operation Instruction Before installing the MASS-VIEW® it is important to be sure whether you received the right model using the packing list and the attached label on the instrument. Be sure the piping system is clean. For absolute cleanliness always install filters to assure a moisture and oil-free gas stream. -

Page 5: General Product Information
BRONKHORST® General Product Information Introduction ® MASS-VIEW instruments are accurate instruments for measuring and controlling the mass flow rate of gases. These smart instruments offer multiple process values as input- or output parameters. Many parameters can be changed on the instrument through the menu, other parameters can only be changed using our digital interfaces. -

Bronkhorst High-Tech B.V., these costs are added to the repair invoice. Import and/or export charges, foreign shipping methods/carriers are paid for by the customer. -
Page 7: Sensor Principle
BRONKHORST® Sensor principle ® The MASS-VIEW operates on the principle of direct thermal mass flow measurement. The thru-flow design sensor consists of a heater resistor and a temperature sensing resistor. Both resistors are made of temperature sensitive resistive material that is covered with a stainless steel tube. The necessary heating power to keep the temperature difference between the heater resistor and the sensing resistor at a constant level depends on the mass flow. -

FlowDDE communicates very easily with Microsoft Excel and other applications. FlowPlot (needs FlowDDE). Flow-Plot is a DDE-client program for service-purposes on Bronkhorst® digital instruments or readout-units. It gives good insight into the dynamic behaviour of digital instruments. FlowView (needs FlowDDE). -
Page 10: Installation
BRONKHORST® Installation Unpacking and inspection Check the outside packing box for damage incurred during shipment. Should the packing box be damaged, then the local carrier must be notified at once regarding his liability, if so required. At the same time a report should be submitted to your supplier. -
Page 11: Mounting
BRONKHORST® Mounting ® The mounting position of the MASS-VIEW is vertical, although it is possible to turn the device 180° and change the display setting. Avoid installation in close proximity of mechanic vibration and/or heat sources. In-line filter Although the gases to be measured should be absolutely free of dirt, oil, moisture and other particles, it is recommended to install an in-line filter upstream of the flow meter / controller, and if backflow can occur, a downstream filter is recommended too. -

Page 13: System Purging
BRONKHORST® 2.10 System purging If explosive gases are to be used, purge the process with inert dry gas like Nitrogen, Argon etc. for at least 30 minutes. Complete purging is also required to remove such gases from the system before exposing the system to air. -
Page 14: Operation
Operation General Bronkhorst® instruments are designed in such a way that they will meet user process requirements in the best possible way. Flow meters and controllers are powered from a dc power source with a minimal ripple. When providing your own power supply be sure that voltage and current rating are according to the specifications of the instrument and furthermore that the source is capable of delivering enough energy to the instrument. -

BRONKHORST® User Interface, menu structure and instrument functions 3.4.1 The readout screen ® The readout screen of the MASS-VIEW is divided into several blocks as described in the picture on the right. 1. At the top of the screen the fluid name and the unit dimensions are displayed. -
Page 16: The Menu Structure
BRONKHORST® 3.4.3 The menu structure From the readout screen one can enter the menu by pressing enter. One can navigate through the menu-items using up and down and enter the selected item by pressing enter. Select the “back” option to return to the readout screen or to go up one level in the menu. -
Page 17: Sleep Mode
BRONKHORST® 3.4.4 Sleep mode To increase the lifetime of the display a sleep mode is built-in which displays the flow at a random place on the screen. The sleep mode will become active when the readout screen is visible and no button is pressed for a number of minutes. -
Page 18: Alarm Outputs
BRONKHORST® Mode (FlowDDE parameter 156) With the “mode” parameter the user can choose if the alarms reset automatically or manually. When the reset mode is set to automatic, the alarms will be reset when measure reaches the desired level and the delay time has exceeded. -
Page 19: Other Gases
BRONKHORST® Other gases ® The MASS-VIEW series are calibrated on Air. All other pre-installed gases are calculated using a theoretical conversion model which describes the flow curve for other gases which will introduce additional inaccuracies. However, as the accuracy of the conversion model also depends on viscosity, pressure and temperature, special attention should be taken for gases in the heterogeneous gas state where specific heat, density, thermal conductivity and viscosity can vary tremendously. -
Page 20: Maintenance
In case of severe contamination it may be required to clean the inside of the instrument. After cleaning a recalibration is needed. Bronkhorst® has a trained staff of servicemen available. Contact Mass Flow ONLINE B.V. for cleaning and recalibration options. -
Page 21: Troubleshooting
BRONKHORST® Troubleshooting General ® For a correct analysis of the proper operation of the MASS-VIEW meter it is recommended to remove the unit from the process line and check it without applying gas supply pressure. In case the unit is dirty, this can be ascertained immediately by loosening the couplings.
