1 General Specifications Model RGL Rotameter This type of Rotameter is designed for measurement of liquids and gases. The conical glass metering tube has a free rotating float. This float is mounted in a vertical pipeline with flow direction upwards. The flow is indicated by the top of the float and can be read from the standard scale on the metering tube or from a connected scale. When the process conditions are changed the scale needs to be replaced by a new one of which the values should be calculated. FETURES - Large selection of measuring ranges - nti-static metering tubes for measurement of small quantities of gas - High accuracy of free rotating float even at low flow rates - Low pressure loss - Visual check of the medium - Non-powered local indication - Large selection of scales - Optional built-in valve - Exact scale calculation at changed process conditions according to VE/VI guidelines 3513 with the use of the flow table (option /PT) with K-metering tube with M-metering tube with L-metering tube STNR SPEIFITIONS Measurable flow rates - Water (20 ) : l/h bis 110 l/h - ir (20 ; 1 bar abs.): 0.1 l/h bis l/h Measuring range - K metering tube : 10:1 - M metering tube : 20:1 (10:1) - L metering tube : 20:1 Metering tubes : K6; M6; L6; K7; R7; M7; L7 ccuracy Glass Metering Tube R741 - R743 K631 - K743 M613 - M622 M624 - M747 L613 - L623 L624 - L747 Length 75mm 75mm 150mm 150mm 300mm 300mm ccuracy class acc.

However, in certain situations the switch may react from off to on. In such cases the customer has to assure by himself that this does not happen. Normally the behavior can be improved by more distance to the EM-source or by using a different cable position. ONTROLLER (OPTION /R1 and /R3) ifferential pressure controller for a constant flow at fluctuations of the back pressure. These are no pressure limiting valves. - The controller /R1is for liquids with variable inlet or outlet pressure and for gases with variable inlet pressure and constant back pressure. - The controller /R3 is for gases with fluctuations of the back pressure.
