Portable battery powered mass flow meter The MASS-VIEW® series provides modern, novel and economical alternative to variable area meters (VA meters), also known as purge meters. The rechargeable Battery Pack enables you to take the MASS-VIEW series as a portable mass flow controller for remote locations where line power is not available. It provides the ability to power up and operate your flow controller continuous for 24 hours on a single charge which takes around 4 till 6 hours. The high capacity battery can be recharged even more than 800 times and is protected by a casing of high strength plastic.
Features of using the Battery Powered Flow Controller 1. No line power supply needed anymore;
2. Long operation time (24 hours); 4. recharging takes around 4 till 6 hours; 5. long life cycle over 800 times; 6. Built-in safety circuit against over-charge; 7. Battery protected by high strength plastic.

The fields of application for our mass flow meters are diverse: - Burner Control (furnace construction) - Welding (welding gas monitoring) - Leak measurements (quality, environment) - Coating (equipment construction)
- Regulation of gaseous atmospheres (biotechnology) - Measurements of gas consumption (hospitals) - Test equipment (production maintenance) - Local preparation of a gas mixture - Flow rate monitoring (laboratories)
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.

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.
