1 eneral Specifications Model RAH Rotameter S 01R01B05-00E-E This type of Rotameter is designed for measurement of liquids and gases. The conical glass metering tube has a free rotating float. The mounting position is vertical with flow direction upwards. The flow is indicated by the top position 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. FEATURES - Wide measuring range selection - Anti-static metering tube for low gas flow measurement - Free rotating float for high measurement accuracy even at low flow rates - ow pressure loss - Visible monitoring of the measured medium - ocal indication without resource - Selectable scale - Scale conversion for various processes with the use of the flow table (option /PT) STADARD SPECIFICATIOS Measurable flow rates - Water (0 C) : 0.00 l/h to 10 m3/h - Air (0 C; 1 bar abs.) : 0.1 l/h to 100 m3/h Measuring range - metering tube : 10:1 - metering tube : 0:1 Metering tubes : 6; 7; 0; 1; ; 4 Accuracy: Metering tube Measuring accuracy acc.

Do not use valve with Perbunan gaskets Procedure to select the model code Please specify in the following order - Measuring range for water/liquid or air/gas - With or without optional limit switch - With or without optional valve First select the required measuring range from the flow table (last column) and specify the float insertion for the optional limit switch. Then the suffix code for the combination metering tube - float can be fixed. The suffix code for the measuring tube length/diameter with or without the optional valve completes the model code specification.
