Compressed air and natural gas meters with M-Bus now also directly from the manufacturer. CS Instruments GmbH & Co. KG was the OEM-manufacturer of the ENDYS AIR compressed air meter with M-Bus from 2010 to the end of 2017. The ENDYS AIR products have been marketed exclusively through Hochhut GmbH, wich now works with another manufacturer. The CS Instruments GmbH & Co. KG now offers the products themselves. The successor product of ENDYS AIR now offers ail the possibilities of digitization and is the idéal consumption meter for Industry 4.0. The successor products of the well-known ENDYS AIR company Hochhuth have been metrologically improved and completely revised and in addition to the M-Bus interface also have the following additional outputs or bus systems: • Modbus RTU • Modbus TCP or TCP PoE • Profibus, Profinet • 4..20 mA and pulse • Hard (in preparation) The VA 520, VA 500, VA 550 and VA 570 industrial gas meters with M-Bus are the ideal compressed air meters or consumption meters for natural gas, biogas, methane, nitrogen, argon, carbon dioxide for consumption measurement and flow measurement. VA 520, VA 500, VA 550, VA 570 with M-Bus are idéal for conversion or retrofitting and for new installations of gas meters, compressed air meters, flow meters, etc. to existing or new energy management software according to DIN ISO 50001 and DIN ISO 16247 and building management systems. Advantages: • Direct display in Nm3/h, or NI/min and temperature in C° • Calorimetric measuring principle - no additional pressure and temperature measurement necessary • High measurement accuracy % to 3 inches • VA 500 and VA 550 insert version from % inch to DN 400 / DN 500

VA 520 Compressed air meter with M-Bus Easy installation into the existing pipeline due to in- tegrated measuring section and welding neck according to (EN 1092-1 PN 40) High measuring accuracy due to defined measuring section (inlet and outlet section) Display shows two values at the same time: • Actualflowinm3/h,l/min... • Total consumption(counter reading) in m3,1 • resp. temperature measurement Values indicated in the display turnable by 180°C, e. g. in case of overhead installation At the touch of a button • Reset of counter reading • selection of units • zéro-point adjustment, leak...

VA 570 with M-Bus and integrated measuring section VA 570 is supplied with an integrated measuring section. The measuring sections are available in flanged version or with R resp. NPT thread. A spécial 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). If you want to measure the flow of a spécial gas mixture please contact us. On request we are quite pleased to offer a...

VA 570 with M-Bus Prâzise Verbrauchs-/Durchflussmessung für Druckluft und Gase The new flow sensors VA 550/ 570 work according to the calorimetric measuring principle. Therefore an additional température and pressure compensation is not necessary. Due to its robust design, the aluminum die cast housing, the robust sensor tip made from stainless steel 1,4571, the new VA 550/ 570 are suitable for demanding industrial applications. An ATEX version is available for applications in explosive areas. For flow measurement e. g. of natural gas there is a version with a DVGW admission. Applicable in...

What are the advantages of our M-Bus 1) Even under pressure, the flowsensor VA 500 is mounted by means of a standard 1/2“ bail valve. During mounting and dismounting the safety ring avoids an uncontrolled éjection of the probe which may be caused by the operating pressure. For the mounting into different pipe diameters VA 500 is avaiiabie in the foi-iowing probe lengths: 120, 160, 220, 300, 400 mm. So the flow sensors are being mounted into existing pipeiines with inner diameters of 1/2“ upwards. The exact positioning of the sensor in the middie of the pipe is granted by means of the...

VA 500 - with M-Bus Flow sensor for compressed air and gases The new VA 500 for flow measurement of compressed air and gases, optionally with display for flow in m3/h and total flow in m3. Contrary to the previously used bridge circuit the newly developed evaluation electronics records all measured values digitally. This leads to a better accuracy also in case of large measuring spans of 1:1000. Spécial features: • RS 485 interface, Modbus-RTU as a standard • Incl. temperature measurement • Integrated display for m3/h and m3 • Usable from 1/2“ to DN 1000 • Easy installation under pressure •...
