Mass Flow Meters for Gas: Mass View Flow Gas Meter ( Low Flow )

The MASS-VIEW® series operate on the principle of direct thermal mass flow measurement. A major advantage of using this type of sensor is that the instruments measure direct mass flow, without the need for temperature and pressure correction.

Features:

1. Clear indication in:
    - actual flow rate (bar graph and value)
    - desired flow units
    - type of gas
    - totalised flow
2. Bright, wide-angle OLED display
3. Free of parallax error
4. Virtually independent of temperature and pressure variations
5. Low pressure drop
6. Wide flow ranges
7. Fast response
8. High accuracy
9. Electronic output:
    - Analog (0 .. 5 Vdc)
    - RS-232 interface (with FLOWBUS)
    - Modbus-RTU/ASCII interface
10. Configurable password protection
11. Alarm and counter functions
12. Relays
13. Multi Gas / Multi Range
14. 10 Pre-installed gases
15. Digitally calibrated
16. Free software tools

Applications:

1. Burner Control (furnace construction)
2. Welding (welding gas monitoring)
3. Leak measurements (quality, environment)
4. Coating (equipment construction)
5. Regulation of gaseous atmospheres (biotechnology)
6. Measurements of gas consumption (hospitals)
7. Test equipment (production maintenance)
8. Local preparation of a gas mixture
9. Flow rate monitoring (laboratories)
10. Cutting (steel sheets)
11. Cost centre billing
12. Analytical equipment
13. Aeration / sparging (food products, ice cream / edible oils
14. Blanketing (food)
15. Fermentation (food, biotechnology, pharma)
