Flow Industrial gas meter with M-Bus for compressed air, natural gas, biogas... 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 all the possibilities of digitization and is the ideal 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: Profibus, Profinet 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 ideal 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. 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 ¼ to 3 inches VA 500 and VA 550 insert version from ½ inch to DN 400 / DN 500

Total consumption(counter reading) in m³, l Easy installation into the existing pipeline due to in- tegrated measuring section and welding neck according to (EN 1092-1 PN 40) resp....

Flow VA 520 with M-Bus • Flange version DIN EN 1092-1 Flow measuring ranges VA 520 for compressed air (ISO 1217:1000 mbar, 20 °C) Anschlussgewinde m³/h, l/min (1000 mbar, 20°C) in case of compressed air resp. Nm³/h, Nl/min (1013 mbar, 0°C) in case of gases Units adjustable via keys at display: m³/h, m³/min, l/min, l/s, ft/ min, cfm, m/s, kg/h, kg/min Meas. principle: calorimetric measurement Thermal mass flow sensor Meas. medium: air, gases air, nitrogen, argon, nitrous oxide, CO2, oxygen *Attention: Shorted inlet section! Please observe the recommended minimum inlet section (length = 15 x...

Flow VA 570 with M-Bus and integrated measuring section Flanged version Available with option: Ethernet Modbus/TCP Version with pipe thread R thread or NPT thread 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). Flow...

Flow VA 570 with M-Bus Präzise Verbrauchs-/Durchflussmessung für Druckluft und Gase The new flow sensors VA 550/ 570 work according to the calorimetric measuring principle. Therefore an additional temperature 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....

Flow What are the advantages of our flow measuring technology? 1) Even under pressure, the flow sensor VA 500 is mounted by means of a standard 1/2“ ball valve. During mounting and dismounting the safety ring avoids an uncontrolled ejection of the probe which may be caused by the operating pressure. For the mounting into different pipe diameters VA 500 is available in the following probe lengths: 120, 160, 220, 300, 400 mm. Engraved depth scale for accurate installation mounting depth = x+y dA = outer diameter x = dA 2 1/2“ - ball valve closed So the flow sensors are being mounted into...

Flow 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. Inner diameter adjustable via keypad Special features: • RS 485 interface, Modbus-RTU as a standard • Incl. temperature measurement • Usable from 1/2“ to DN 1000 • Easy installation under...
