Product Description
By-pass rotameters are suitable for economical measurement of flow in larger pipelines generally 2" NB to 14" NB. By-pass rotameters 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/ ISO/BS standards.
