 MODELS: KOE, KOP
|
Model Description
- KOE : Orifice Flow Transmitter(Differential Pressure Transmitter). The DP transmitter inside the instrument ouputs electrical signal proportional to the totalized or instant flow meausured.
- KOP : Orifice Flow Meter(with Float Indicator). The flow is indicated by a float locally.
Features
- Convenient and accurate reading
- Simple structure and simple installation
- Large flow can be measured by relatively small instrument
- Easy to dettach from the piping
- No limitation to the direction of the flow
- The indicator part can be dettached from the piping and the flow element simply and easily for repair and maintenance without disturbing the flow(using cock valve)
- Easy maintenance repair
- A wide selection of materials
- A wide selection of output options

Orifice meters are the most popular flow meter in use today. They are simple in structure but render high accuracy. Their additional merits are that they can measure large flows in big pipes, they are easily availble, they are versatile(can be configured as mass flow meter by applying temperature and pressure compensators at relatively reasonable cost), etc.
It can measure clean and dirty liquids and even slurries. And it can also be used for high-viscosity liquids. The meter can be used for gases also. These meters have found applications in a wide variety of industries including but not limited to paper/fiber, steel, petrochemical, food/beverage, air-conditioning, water treatment, chemical, etc. industries.
Even with the rapid growth of new technology meters such as ultrasonic, electromagnetic and Coriolis meters, this type is still one of our steady sellers.
All the meters are calibrated accurately before shipment and shipped with test and calibration report to ensure the accuracy of the meter. The scales are inscribed with easily visible marking and can use the unit of the customers choice(index, percentage, actual flow(cm3/h, SCFM, etc.))
Meters that exceed the standard flow ranges can also be manufactured.
As standard, the meters are delivered with 1 year of warranty.
INSTALLATION GUIDE
- Metering accuracy of all orifice flowmeters depends on the installation conditions, the orifice area ratio, and the physical properties of the liquid being measured. Therefore extreme cautions should be exercised for installation.
- Straight pipe sections of 3 to 20 diameters upstream and 3 to 5 diameters downstream of the meter should be secured for the accurate measurement of the flow
- Can be installed on vertical and horizontal pipes
- Please install the meter in the direction marked by an arrow.
