New precise flow measurement for compressed air and gases incl. temperature measurement

VA 550 Precise flow measurement for compressed air and gases Application range: • Ideal also for the outdoor area • Compressed air measurement and distribution • Leakage measurement of compressed air and gases • Flow measurement of gases like e. g. nitrogen, argon, carbon dioxide, oxygen and so on • Flow measurement in vacuum systems • Flow measurement of explosive gases like natural gas, methane, propane, hydrogen with ATEX approval • Flow measurement of corrosive, acid gases like e. g. biogas with different gas mixtures • Measurement of oxygen and natural gas at gas burners • Flow...

VA 570 - with integrated measuring sectionFlanged version 395 38 5678562 with option: Ethernet Modbus/TCP VA 570 is supplied with an integrated measuring section. The measuring sections are available in flanged version or with R resp. NPT thread. 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 centering device ensures that the sensor is...

VA 550 - immersion sensor Flow sensor for heavy duty industrial applications incl. temperature measurement.The immersion sensorVA550 is the ideal flow sensorfor installation into existing compressed air resp. gas lines from 3/4“ up to DN 1000. Housing IP 67 Housing twist able, display twist able by 180° (upside down). Settings adjustable via display, consumption counter resetable All medium-touching parts are made from stainless steel 1,4571 Special measurement technology features: • 4 values in the display: Flow, total consumption, velocity, temperature. Unitsfreely adjustable. • Min/max...

Easy mounting/dismounting of VA 550 under pressure- without disconnection of the line - without emptying the line Engraved depth scale If there is no suitable measuring site with 1/2“ ball valve there are twofor precise simple possibilities to set up a measuring point: installation A Weld on a 1/2“ screw neck and screw on a 1/2“ ball valve B Mount spot drilling collar including ball valve By means of the drilling jig it is possible to drill under pressure through the 1/2“ ball valve into the existing pipeline. The drilling chips are collected in a filter. Then the sensor can be...

Configuration ofVA 550 via PC Service Software In general all configurations can be done via the integrated display. For sensors without display there is a PC Service Software available. The following adjustments can be carried out directly at the display resp. by means ofthe PC Service Software: Adjustment of inner diameter of pipe Selection of gastype Selection ofunits: e.g. m3/h, m3/min, l/min, kg/s,... Reset ofcounter Setting ofreference conditions (reference temperature/pressure) Zero point adjustment / leak flow volume suppression Scaling of 4...20 mA output / setting of pulse...

Operation / configuration also in explosive areas The optical keys integrated in the display also function through the glass pane. Advantage: The sensor VA 550 can also be configured in explosive areas without having to open the housing. In case of conventional keys the housing has to be opened for operation. In an explosive area this is often not possible. Modbus interface integrated as a standard Modern building management systems require modern sensors with digital Modbus interface. In case ofthe flow sensors VA550 the measured values like: • Volume flow in Nm3/h, Nm3/min and so on •...
