The products of CS INSTRUMENTS GmbH have been leading in the field of Consumption measurement and Flow measurement of Gases for years. Customers all over the world appreciate the professional support and development spirit behind our products. Through international subsidiaries and a constantly growing, worldwide sales and service network, we provide our customers with the latest Measuring technology and ensure optimum all-round support. For many applications, we offer specially developed and long-term proven systems for consumption and Flow measurement, which, in combination with our specially developed software solutions, are both uniquely effective and efficient.
Flow sensor VA550
For example, our VA550 (insertion version) and VA570 (version with integrated Measuring section) Flow sensors have been specially developed for harsh industrial applications. Thanks to the robust, impact-resistant die-cast aluminum housing, these flow sensors can be easily installed outdoors (IP65). ATEX or DVGW approval is also available on request.
Functionality
All our Flow meters work according to the calorimetric principle and measure the thermal mass flow or Standarized volume flow directly. Additional Temperature and pressure compensation is not necessary. The standard volume is a common unit of volume measurement that is used to compare gas quantities at different pressures and temperatures. In order to comply with various standards, the reference conditions can be set directly on the Display of all our sensors. The Flow meter thus provides the consumption directly in the set standard. While ISO 1217 (1000 mbar, 20 °C) is generally used for compressed air, DIN1343 (1013 mbar, 0 °C) is used for Technical gases.
Is this all too complicated for you? No problem! We are sure to have the right device for your application. Simply contact us, we will be happy to advise you individually on your application and work with you to find the right device.
A factory calibration certificate is always included with our devices. ISO certificates, which are traceable to the national standard, are also available as an option. In contrast to many other measuring methods, the pressure loss caused by our flow measurement is negligible.
Each flow meter can be equipped with various interfaces to ensure connection to your control technology, Data loggers or evaluation devices. These include, for example, 4...20mA, pulse, Modbus RTU, M-Bus or Ethernet.

Good to know
In addition to Flow measurement, our sensors can also be used to measure leakage quantities. This provides the user with information on possible energy savings. The insertion version is the ideal flow meter for existing compressed air and gas lines and can be easily installed and removed under pressure via a ½" Ball valve. The flow sensor is available with different shaft lengths and can also be used in very large pipelines > DN 1000 or rectangular ducts.
