Orifice Flowmeters Manufacturers

Orifice Flowmeters used for the absolute calibration of flow meters. They provide calibration at flowrates greater than 200 1/min. These show a slightly higher stream flow than the ASME sharp-edged orifice. They employ a tapered float assembly and a fixed diameter orifce. They are generally less expensive to install and manufacture than the other commonly used differential pressure flowmeters. This is installed between flanges connecting two pipe sections. They are less than 0.05D thick.
