% Since the area of the flow passage increases as the float moves up the tube, the scale is approximately linear. /Width 3467 Start your sales inquiry online and an expert will connect with you. << When there is no liquid flow, the float rests freely at the bottom of the rotameter. They also fit a wide variety of end fittings and connections. is the the least surface of the annular orifice of the fluid flow, corresponding to the height of the float H with respect to the initial section of the pipe, is the float density, is the fluid density. The calibration of the glass rotameter is obtained by using water and dry air which are close to the ideal fluid as the medium. /Filter /FlateDecode GlobalSpec may share your personal information and website activity with our clients for which you express explicit interest, or with vendors looking to reach people like you. 
Glass- Borosilicate glass is used to make the tapered metering tube and was the original material used to make rotatmeters. They are designed to facilitate setting and accurately controlling low flow rates, typically in the purging of liquid or gas from measurement piping.
