The thermal flow direction switch VA 409 with direction indication serves for determination of the flow direction of compressed air and gases especially in closed circular pipelines. By means of VA 409 with flow direction indication the flow direction of the compressed air can be determined quickly and safely. Compared with the former mechanical paddle flow switches VA 409 is able to detect even the smallest changes in the flow direction quickly and without any mechanical movement. The direction information in form of a potential-free contact (normally closed max. 60 VDC, 0.5 A) is transferred to the flow sensors VA 5xx or to a separate building management system (mbs). Two LEDs show the flow direction. In connection with 2 flow sensors VA 5xx incoming and out flowing compressed air in closed circular pipelines can be measured precisely.

Special features:

• Detects smallest changes < 0,1 m/s referrend to 20°C and 1.000 mbar 
• No mechanical wear parts 
• Easy installation under pressure

The entry of the correct inner diameter is essential for an accurate consumption measurement. 

The thickness meter CS 0495 enables a quick, easy and accurate measurement of the wall thickness of pipes. So the determination of the inner diameter becomes very easy. 

Our long-term hands-on experience in measurement and control technology was implemented in the new DS 400. From recording of the measured data, automatic sensor identification, indication on a big colour screen, alerting, storage up to remote read-out via web server, all that is possible with DS 400. By means of the CS-Soft, software alarms can be sent via SMS or e-mail. On the big 3.5' colour screen with touch panel all information is available at a glance. The operation is very easy. All measured values, measured curves and threshold exceedings are indicated. The progression of the curve, since the beginning of the measurement, can be viewed by an easy slide of the finger. The huge difference to ordinary paperless chart recorders reveals in the easy initiation as well as in the evaluation of the measured data. All sensors are identified directly and powered by DS 400. Everything is matched and tuned. 

Features:

From recording of the measured data, indication on a big color screen, alerting, storage up to remote read-out via webserver... this is all possible with DS 500. By means of the webserver software alarms can be sent via SMS or e-mail. All measured values, measured curves and threshold exceeding are indicated. The curve progressions from the beginning of the measurement can be viewed by an easy slide of the finger. Daily/weekly/monthly reports with costs in € and counter reading in m³ for each consumption sensor are completing the sophisticated system concept.
