VA 520 - Thermal mass flow meter for flow measurement
for compressed air and gases. New digital electronics - improved accuracy.
Details
- All wetted parts are made of stainless steel, especially for applications with high demands on cleanliness and surface quality
- Robust aluminum housing makes rough industrial applications possible
- Recommended for flammable gases such as Natural gas, hydrogen, Biogas, etc. due to ATEX or DVGW approval
- Measuring the mass flow, direct output of the Standarized volume flow
- Highly accurate for both small and large flows
- Pressure and temperature-compensated thanks to the thermal mass flow principle
- Quick and easy installation via a standard ½'' Ball valve
- No moving parts, therefore Low maintenance
- Disappearingly low pressure loss, as the blockage of the diameter is negligible
- 04...20 mA, pulse and a Modbus RTU (RS 485) interface as standard, optional interfaces such as Modbus TCP (Ethernet), PoE, M-Bus
- Pressure range up to 50 bar, special version up to 100 bar
- Media temperature range up to 180 °C (ATEX version up to 120 °C)
- Protection class IP 67 (IP 64 for ATEX II 2D Ex tb IIIC T90°C Db)
- Integrated display for showing Measured values
- Suitable as insertion version for 3/4" to DN 1000
- Simple installation under pressure
- Settings can be adjusted using the buttons on the Display
- Main meter 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
