  • By Pass Rotameters

    By Pass Rotameters

    By-pass Rotameters are suitable for economical measurement of flow in larger pipelines generally 2" NB to 14" NB. The construction is simple and reliable consisting of orifice plate with carrier ring and a shunt Rotameter. The flow rate through the Rotameter is proportional to the pressure drop across the orifice plate created by the main flow and is calibrated accordingly. During installation care should be taken to ensure laminar flow in the pipe section. Orifice plate dimensions are based on ISA ISOBS standards. By Pass Rotameter is an inference type Flow Meter.

  • Glass Tube Rotameter

    Glass Tube Rotameter

    Glass Tube Rotameter is basically a Variable Area Flow Meter. The differential pressure across the annulus area is constant and the flow rate is measured as a function of the annulus area. Glass Tube Rotameters consist of a tapered glass tube mounted vertically in a frame with the small diameter at the bottom and large end up. The tube contains a free moving float that rests on the stopper at the base of the tube. When the liquid flows, the float rises until its weight is balanced by the up thrust of the fluid and the float reaches a position of equilibrium. At this position it indicates the instantaneous rate of flow. The flow rate can be read from the adjacent scale.
