This book a popular, indispensable tool for those who encounter gas pressure regulators and measur- ing devices in their daily work. The RMG Pocket Book contains important technical parameters and explanations of underlying theory. All data and indications stated were valid on the day of publication. However, RMG reserves the right to change parameters without further notice. Note for planners: Use the Pocket Book, CD-ROM and RMG website (www.rmg.com) for a provisional pre-selection of RMG products. For more detailed information, go to www.rmg.com/produkte.html or www. rmg.com/download.html. If you still need additional information, ask for our brochures. There are Technical Product Information brochures for all products containing a functional description, dimensional details, measuring-line connection sizes, etc. For example, the brochure RMG 402 is titled: Technical Product Information – Gas Pressure Regulator (Also see pdf files on CD-ROM and the web). In addition please utilize the information and installation guidelines contained in our General Operating Manual for Gas Pressure Regulators and Safety Devices. Please do not hesitate to contact our engineers should you have any additional questions. Did you know that RMG organises technical seminars to help customers extend their technical knowledge? We wish you success in all your dealings with the latest edition of the RMG Pocket Book.
