CS Instruments VA 570 – Thermal Mass Flow Meter is a flow meter with an integrated measuring section for compressed air and other gases. Measure and reduce your energy costs and increase your sustainability with the VA 570 flow meter. Monitor your consumption and analyze your leakage rate with a stationary flow meter in distribution stations, in front of individual departments, or for billing purposes of individual consumers. VA 570 is supplied with an integrated measuring section. The measuring sections are available in a flanged version or with R resp. NPT thread.

CS Instruments VA 570 – Thermal Mass Flow Meter

A special feature is the removable measuring head. So the measuring unit can be removed easily and quickly for calibration or cleaning
purposes without having to dismount the measuring section intricately. During this period the measuring section is sealed by a closing
cap (accessory). The screwing with a centering device is designed such that the sensor is positioned accurately in the center when screwing it into the measuring section; furthermore, it enables an exact positioning in the flow direction. This eliminates unnecessary measuring faults.

Features

Measurement of mass flow, direct output of standard volume flow, without additional measurement of pressure and temperature, possible
All wetted parts of the VA 570 are made of stainless steel, especially for applications with high demands on cleanliness and surface quality
The robust aluminum housing is ideally suited for harsh industrial conditions as well as for outdoor installations
No moving parts, therefore low maintenance
Vanishingly low pressure loss due to vanishingly low blockage of the diameter
ATEX or DVGW certification available, thus recommended for gases such as natural gas, hydrogen, biogas, etc.
Highly accurate at small as well as large flow rates
Pressure and temperature compensated by the thermal mass flow principle
Easy installation and removal of the sensor from the measuring section, the measuring section can remain in the line for cleaning or recalibration of the sensor and can simply be closed with a sealing cap
