By-pass Rotameter / Differential pressure transmitter
KOP and KOE series is low-cost flow meter for liquids and gases based on orifice principle. KOP series combines a variable area flow meter (rotameter) and orifice flow meter principles. A small sized glass-tube or metal-tube variable area flow meter (rotameter) is attached to the meter tube that has an orifice on the inside. So, it’s a combination of orifice flow meter and variable area flow meter (rotameter). The main components of this series are meter body with orifice, connection, taper tube (glass or metal tube), float, isolating valve and options. KOE series combines a dP (differential pressure) indicator/transmitter and orifice meter body and comes with versatile computation and analog and digital output options. The meter is installed in line with pipe using flange, screw or wafer (sandwich type) connections. The material of the meter can be stainless steel, PVC, Teflonlined, all Teflon, etc. to meet to resistance requirements to various chemical and physical properties of liquids or gases. The meter body can be installed freely both horizontally and vertically. So, it’s easy to adapt to the tough site environments. Isolation valves are installed between the meter body and the indicator, so that there’s no need to install by-pass piping for maintenance and repair of the meter and it also saves the total cost of purchasing and installing the meter. The meter comes with various options for controlling of the process such as Reed swithes.
