Measurement of the mass flow, direct output of the standard volume flow possible without additional measurement of pressure and temperature
All wetted parts of the VA 570 are made of stainless steel, especially for applications with high demands on purity and surface quality
The robust aluminium housing is ideal for harsh industrial conditions as well as outdoor installations
No moving parts, therefore low maintenance
Minimised pressure loss due to extremely low blockage of the diameter
ATEX + IECEx or DVGW approval available, therefore recommended for gases such as natural gas, hydrogen, biogas, etc.
Highly accurate for both small and large flow rates
Pressure and temperature-compensated thanks to the thermal mass flow principle
Easy installation and removal of the sensor from the measuring section, the measuring section can remain in the pipe for cleaning or recalibration of the sensor and can simply be closed with a sealing cap
For speeds up to 224 Nm/s
Media temperature range up to 180 °C (ATEX + IECEx version up to 120 °C)
Maximum pressure 16 bar, up to 40 bar in the PN 40 special version
Can be used from DN15 to DN 80
Highly accurate with an accuracy of ±1.5% or ±1% of the measured value and ±0.3% of the final value
04...20 mA, pulse and a Modbus RTU (RS 485) interface as standard, optional interfaces such as two galvanically isolated analogue outputs (04...20 mA), Modbus TCP (Ethernet), PoE, M-Bus
Protection class IP 67 (IP 65 for ATEX + IECEx)
Integrated display to show the measured values
Settings can be changed using the buttons on the display
Main counter status can be reset via the display
