Air flow meters and mass flow meters from CS Instruments work according to the calorimetric measuring principle. This means, while measuring the thermal mass flow or standard volume flow, no additional temperature and pressure compensation is necessary. The standard volume is a common volumetric unit used to compare gas quantities at different pressures and temperatures. In order to meet various standards, the reference conditions can be set directly on the display of the flow meter. Thus, our flow meters provide consumption and flow measurement within the standard our customers wish to use them.

CS Instruments GmbH has been an expert in the field of consumption and flow measurement for many years and serves customers worldwide with the most advanced flow meters. For this reason, we offer a wide range of field proven tools for most applications. The consumption sensors of our VA550 and VA570, for example, have been developed especially for rough industrial applications. Thanks to their robust, impact-resistant aluminum die-cast housing, these flow meters can easily be installed outdoors (IP65). On request, we also offer an ATEX approval for our flow meters. Those measurement devices can be used up to a maximum pressure of 100 bar and a maximum temperature of 180 °C. Our direct immersion variants are the ideal flow meters for existing compressed air and gas lines and can be easily installed and removed under pressure via a ½" ball valve. Those flow sensors are available with different shaft lengths and can also be used in very large pipelines > DN 1000 or rectangular ducts.
Within the package of all our flow measurement devices there is always a factory calibration certificate. Optionally, ISO certificates are also available, which can be traced back to the national standard. While ISO 1217 (1000 mbar, 20 ° C) is generally used to measure compressed air flows, DIN1343 (1013 mbar, 0 ° C) is used to measure most industrial gases. In addition to the consumption measurement, our flow meters can also be used for leakage measurement and leakage detection. Therefore, our flow measurement devices are the perfect tools to provide users with all necessary information on possible energy savings.
In contrast to many other working principles, the pressure loss resulting from our consumption measurement method is negligible. Each consumption meter can be equipped with various interfaces and thus ensures the connection to your control technology, data loggers or evaluation devices. These include e.g. 4 ... 20mA, pulse, Modbus RTU, M-BUS or even Ethernet. Our thermal mass flow meters can also cover a wide range of applications and media (compressed air, carbon dioxide, vacuum, nitrogen, oxygen, ozone, natural gas, hydrogen, argon, helium, biogas, etc.)
Our philosophy is to help our customers finding the products that exactly meet with their needs. Therefore, we are looking forward to give you a free consultation which flow meter or flow measurement equipment would be the correct choice for you. Just use our contact form or simply give as a call.
