Measuring range 2 to 224 m/s / 600 m/s (Compressed air / gases) or 0.04 to 500 mbar differential pressure for Gases.
Measuring range 2 to 224 m/s / 600 m/s (Compressed air) 0.04 to 500 mbar Differential pressure for Gases.
Measuring section made of stainless steel 1.4301 incl. ball valve, up to DN 65 (R2 1/2") with external thread, from DN 80 with weld neck flange according to DIN 2633.
If there is no measuring site with 1/2 Ball valve on existing pipework, a measuring site can be set up quickly and inexpensively using Spot drilling collars.
By means of a special drilling device a measuring site with 1/2" ball valve can be easily set up within a few minutes.
The supplementary device "high-pressure protection" serves for a safe installation and fastening of the CS sensors VA 500 under pressure.
enables a quick, easy and accurate measurement of the wall thickness of pipes.
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 tried-and-tested systems for consumption and Flow measurement, which, in combination with our specially developed software solutions, are both uniquely effective and efficient.
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 aluminium housing, these flow sensors can be easily installed outdoors (IP65). ATEX or DVGW approval is also available on request.
Our volumetric flow sensors work with different physical measuring principles and thus enable the precise detection of Flow, mass flow or Standarized volume flow for numerous gas applications. Each Measuring principle offers specific advantages to provide the optimum solution for different requirements:
The Vortex sensors (VU and VX) and the differential pressure sensors (VD series) are equipped with integrated temperature and pressure measurement so that the mass flow or Standarized volume flow is calculated directly. This enables simple installation in the pipe without the need for an external flow calculator.
The standard volume is a unit of volume measurement that enables the comparison of gas volumes at different pressures and temperatures. With all our sensors, the reference conditions can be flexibly set on the Display to show Standarized volume flows according to common standards (ISO 1217 for Compressed air and DIN 1343 for Technical gases). This ensures a reliable, standard-compliant consumption display.
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.
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 pipes 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 pipework > DN 1000 or rectangular ducts.
