VA 570 - Thermal mass flow sensor for flow measurement

Details

• 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
• Disappearingly low pressure loss, as the blockage of the diameter is negligible
• 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
