Display menu

The 4-way button with center push gives access to a user-friendly menu, e.g. for zero function, for selection of pre-installed gases in pre-installed ranges, setting of engineering units, alarm functions (minimum/maximum/counter limit) and counter functions. Password protection is provided to prevent unauthorizes changes. Above overview of the MASS-VIEW® menu functions illustrates the great versatility of this product line.

Packing & Delivery

Orders are shipped from Monday through Friday. Weekend delivery is not available. Products will be sold from stock, unless otherwise stated in the purchasing process. You will be notified when an item is not in stock which will introduce a delay in the delivery time. We do not partially ship orders so when one required item is in stock but another is on a non stock lead time then you should split the order. Once your product(s) has shipped, you will receive a shipment notification via email from our shipper United Parcel Services (UPS). In this email, you will find the tracking number of the shipment.

Our Certifications

Calibration certificate

The Bronkhorst Calibration Centre is accredited by the Dutch Accreditation Council (RvA) under registration number K 127. Herewith is certified that our laboratory’s Quality Assurance system, calibration methods and technical competences have been inspected and audited and meet all necessary requirements.

Quality Management System certificate

Bureau Veritas Certification declares that the Quality Management
System of Bronkhorst High-Tech B.V. organisation has been audited
and found to be in accordance with the requirements of the
managment system standards.


Q: Calibration interval

A: Mass flow instruments, in fact all process instruments, experience wear from the conditions of the process in which they are installed. Temperature, electronic component tolerance shift, contamination build up over time (even very slight), plus other factors will all contribute to affecting the accuracy of an instrument.
Your instruments should regularly undergo, at a minimum, a calibration check if not a recalibration. But how often? Because the nature of each application is different (conditions, running time, etc.) a calibration can last three years or three months.
Bronkhorst® instruments do not have specified due dates for calibration. Bronkhorst® suggests that our instruments be calibrated every year. However based on the application conditions, and perhaps company quality procedures, each customer must determine when they need to send in an instrument for recalibration.
Properly calibrated instruments will be more accurate, more reliable, help ensure consistency, and help improve production yields.

Q: What communication possibilities can be used with MASS-VIEW?

A: MASS-VIEW® has two communication options:
– FLOWBUS over RS-232
– MODBus RTU or ASCII over RS-485
There is no FLOWBUS over RS-485 communication possible.
FLOWBUS over RS-232 is mostly used to communicate directly to a PC (running FLOWDDE + FLOWPLOT). RS-232 is a point-to-point connection.
MODBus RTU or ASCII is mostly used when a fieldbus is used to connect several instruments to one bus.

Q: Does the counter remember its value when the instrument is powered off?

A: Every few seconds, the MASS-VIEW® writes the countervalue to a non-volatile memory to be sure no data is lost after a powerfailure.

Q: From which measurement value does the counter start to count?

A: The counter function will start counting a measured value when the instrument measures a value of 2% or higher of its capacity. Below 2% nothing is counted.
