Orifice Flow Meter (Series KOP/KOE)

Transcription

1 Overview 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. 100% ustomer Satisfaction (Series KOP/KOE) The material of the meter can be stainless steel, PV, 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. KOP- Main Features Low ost & High Performance Thanks to unique orifice by-pass system, total instrumentation cost is saved especially for medium and large sized piping ompact Design Small sized indicator saves space in plants. Easy Installation Screw, Flange or Wafer can be used to install the meter in line. There s no need for by-pass piping for repair and maintenance. KOP-F For All Flow Directions Bottom-Top, Top-Bottom, Left-Right and Right-Left flow direction. hange of flow direction is possible even after installation. KOP-N Alarm ontact Besides local flow indication, alarm contact (s) are available. Thus it can be used as Flow Switch. KOE Easy Maintenance Simple design and limited number of parts saves maintenance workload. High Anti-orrosive apability arbon steel, stainless steel and PV (PV) versions are available for various corrosive fluid applications.

2 Operation Principle As shown in the figure, because liquid or gas stream inside the pipe is restricted or throttled by reducing the section area of the pipe using orifice plate, a differential pressure is generated across this orifice plate, meaning the pressure immediately downstream of the orifice is lower than that immediately upstream. The difference of pressures upstream and downstream (dp, differential pressure) corresponds to the flow rate based on Bernoulli s continuity principle. The flow rate thus can be calculated based on this differential pressure. In KOP series (except for KOP-DP series that measures differential pressure directly using manometer), this differential pressure thus generated is converted to flow rate using variable area flow meter. The inlet (bottom) and outlet (top) of the indicator (variable area flow meter) are connected to taps placed immediately upstream and downstream of the meter body. When the fluid flows through this orifice, due to the differential pressure, the fluids flows out into the inlet of the variable area flow meter, through the tapered-tube and float, out of the outlet and back into the main stream. The fluid flowing through the tapered-tube floats the float, the height of which corresponds to the flow rate of the main stream. (For more information, please see the principle of variable area flow meters in our KA (glass-tube) and KM (metal-tube) series catalogs.) The flow rate is engraved on the indicator scale and by reading the float position on the scale, the flow rate can be read. Applications Hot and cold water as well as air flow measurement in air conditioning Medium and large line measurement in general process industry ooling water lines Water treatment process Pure and ultra-pure water production facilities Testing of fire fighting pumps Testing of blowers Etc. 2

3 Installation The meter can be installed either on a horizontal or vertical lines freely. The meter can be installed for all flow directions bottom to top, top to bottom, left to right and right to left. The indicator of the meter can be remotely mounted using impulse line. (In the above, the indicator is below the pipeline.) The indicator of the meter can be remotely mounted using impulse line. (In the above, the indicator is above the pipeline.) 3
