VA 550 - Thermal mass flow sensor for flow measurement
Insertion type sensor for demanding industrial applications, with ATEX approval for Ex zones or DVGW approval for use in natural gas.
Details
- Measurement of mass flow rate, output of standard volume flow rate
- High accuracy for both small and large flows
- Pressure and temperature compensated by the thermal mass flow principle
- Easy installation and removal of the sensor, the integrated measuring section can remain in the line for cleaning or recalibration of the sensor and can simply be closed with a sealing cap
- No moving parts, therefore low maintenance
- Vanishingly low pressure loss due to vanishingly low blockage of the diameter
- Can be used for compressed air and non-corrosive gases such as nitrogen, oxygen, argon, helium, etc.
- 04...20 mA, pulse and a Modbus RTU (RS 485) interface as standard, optional interfaces such as Modbus TCP (Ethernet), PoE, M-Bus
- Optional interfaces such as Modbus TCP (Ethernet), PoE, M-Bus
- Optional: Bi-directional measurement
- Pressure range up to 40 bar
- Temperature range from -30 to 80°C
- Protection class IP65
- Integrated display to show the measured values
- Can be used from DN 8 to DN 80
- Settings adjustable via the keys of the display
- Main counter reading can be reset via the display
- For velocities up to 224 Nm/s
- Highly accurate with an accuracy of ± 1.5% or ± 1% of the measured value - as well as ± 0.3% of the final value
