DIGITAL INSTRUMENTS 2.1 General The digital instruments of M+W Instruments GmbH are measurement devices for thermal mass flow and control of gases. They are equipped with a digital electronic multi-bus pc-board and consist of a micro-controller with peripheral circuitry for measuring, controlling and communication.

All devices have Withworth pipe threads – type RP – according to ISO228-1 (cylindrical G-threads in inches according to BSPP). The mounting of NPT-fittings will destroy the inlet threads in the instrument’s body. Using an inlet pipe with sufficient piping diameter is recommended. The length of the inlet pipe should be at least 10 times the piping diameter.
2.3 Operation and Maintenance When the power is switched on a warm-up period of at least 30 sec is required allowing the instrument’s thermal stabilisation. Afterwards the instrument will work with an accuracy of approximately 4% FS. It takes around 30 minutes until the optimal stability is reached and the instrument will work with an accuracy of <...
The instrument compares setpoint and actual value and controls the valve, until both values match within the tolerances. 2.5 Specifications of MASS-STREAM Digital Instruments D-6300 Measurement System Accuracy ± 2% FS including non-linearity (based on calibration with Air) (± 1% FS or ± 1.5% FS on request) Repeatability <...

MEASUREMENT PRINCIPLE AND CALIBRATION 3.1 CTA Through-Flow Measurement The direct through-flow measurement with CTA (Constant Temperature Anemometry) is also named inline measurement. The working principle is based on King’s law of the ratio between the heater energy and the heat degradation by means of gas flow or liquid flows published in 1914.
3.2 Calibration and Look-up Table The calibration is processed with a mass flow controller which functions as a reference. The controller and the gas inlet pressure forward a defined gas flow, thus a raw signal of the sensor can be allocated to each specific mass flow. To generate and store the look-up table in the instrument up to 21 measurement points are recorded and equally arranged over the total measurement range.
OPERATION VIA RS232 To operate the device from a personal computer via the serial interface it is recommended to install the FlowDDE software. Like other software it can be found on the CD which is accompanying the despatched goods. FlowDDE is required for the following software operations.

Having selected the COM-Port and Baud-Rate you need to start the communication between a personal computer and the instrument via ‚F3’ or by clicking on the menu “Communication“, being followed by a second click on “Open communication“. FlowDDE on your monitor should show the following picture: MASS-STREAM Instruction Manual D-6300 Page 18 off 34...
® The Bronkhorst FlowView software is ideal for easily used standard operations. FlowView can be found on the CD which is accompanying the despatched goods and can be down-loaded from http://downloads.bronkhorst.com.

MANUAL INTERFACE: Micro Switches and LED’s The micro-switch on top of the digital instrument can be used to start a certain function on the instrument. When the switch is pressed down, both LED’s will start indicating different patterns in a loop. The switch has to be pressed down until the 2 LED’s are indicating the right pattern.

Readout of bus-address/MAC-ID and baud rate: Pressing the micro switch 3 times briefly with intervals of max 1 second in normal running/operation mode will trigger the instrument to “show” its bus address/MAC-ID and baud rate. For the indication of the bus-address/MAC-ID the green LED will flash the amount of tens and the red LED the amount of units in the number.

The instrument returns to the “normal running/operation mode“. Changes are valid when they are made within the time-out period (60 sec). The actual setting of the bus address/MAC-ID and baud rate can be checked by pressing the switch 3 times briefly with intervals of max 1 sec. For more details see also table 5. Note 1: The value zero will be indicated by a period of 1 sec off (0.5 sec off / 0.5 sec.
