INSTRUCTION FOR USAGE OF FLOWMETER
For the correct usage of the Flowmeter, Installation, Maintenance, Repair and Inspection
shall be done at the site. No matter how excellent in the design and best parts applied
in the Flowmeter, not only the flowmeter is bad in its performance but also the whole
system is low in the creditability and safety without good consideration on the Process,
and well organized work control and maintenance plan.
Hence, due to the Carelessness in installation and maintenance of the Flowmeter in the
Process can cause the bad performance or malfunction of the whole system, the correct
installation and proper maintenance program shall be set up as a part of the Process
and executed by the plan.
2. Installation
(1) Flometer Diagram
It is designed the basic piping diagram to maximize the performance of the flowmeter,
As shown on Fig.1-1, each entity has own role and is required for the accurate
measurement of the flow rate. But, the actual "Flowmeter Diagram"can be differed by
the principle of the applied flowmeter and the fluid flow to be measured, then please
refer this manual carefully to make the proper diagram. Also simple explanations for
each entity are added.

①AMBIENT TEMPERATURE
⑥Avoid in the piping occurred the cavitation effect.
⑦Must keep the required straight line length by the type of the flowmeter.

(2) Installation Condition
For the accurate and consistent measurement, it is recommended to install the
flowmeter with cautions as the below.
▷Install the Flowmeter at the place where the temperature keep in constant or
change in small.
▷The allowable temperature in the installed place shall be complied to the
Specification of the Flowmeter.
②ATMOSPHERE
▷Avoid the place existing the corrosive gas.
▷Don't let the water flow into the conduit or stay in.
③Install at the place without or minimized the shock and vibration.
④Keep enough space for the maintenance and repair.
⑤Avoid the place existing Electromagnetic Interference.

(3) Installation
It shall be installed by the instruction specified and flushed the flowmeter prior
to the installation.
①Confirm the flow direction with the indication on the flowmeter.
②Use the correct size of the tightening bolts with the Pipe.
③Install the seal such as gasket to prevent from leaking.
④Tighten the bolts with the constant force and the diagonal directional sequence.
⑤Follow the specified earthing method in electrical works.
(refer to the attached wiring diagram)
(4) Maintence and Check
Generally the maintenance program can be classified by two types; Precautionary
program and Post program.
In Precautionary program, it is included in the Internal Check List for the precaution
maintenance and checking method for each type of the flowmeter.
①Seperator
This is the device to reduce the error on reading due to the air or steam
included in the fluid flow. It shall be applied in the system using the mass flowmeter.
②Strainer (Filter)
This is the device to prevent the damage by collecting the dust, chips, sand or
other foreign substances in the fluid flow.
③Flow Conditioner
The is the device installed at the upstream of the flowmeter in order to minimize
the effects on the flowmeter characteristics by removing or reducing the vortex,

make the flow stable, and a priority factor to be considered in the design of the
piping line.
It is recommended to design the Piping Line that the maintenance, repair, inspect
If the flow control V/V was placed in upstream of the flowmeter, it could be
interfered to the flow and the correct measurement could not expected. Hence, it

④Straight Piping Line
It is the straight part of the piping line between the upstream and downstream

1. General
The flow rate can be obtained by measuring the Pressure difference of the flow through
the FLAPPER & Spring tension Interrelation and flow measurement.
This type of Flowmeter has some advantages such as simple structure, easy to handle
and wide application from small to large flow.
2. Standard Feature
(1) DIAMETER : 1" - 20"
(2) TEST PRESSURE : 10Kgf/㎤G(Max),Option (20kgf/㎠2)
(3) MAX. OPERATING TEMP : 120℃
(4) ACCURACY : F․S ±5%
3. Characteristics
(1) Simple and clear reading the instant flow in piping.
(2) Simple structure and easy installation.
(3) Compact size and available for the large flow measurement.
4. Installation and Maintence
(1) Install the Flowmeter in matching the Measuring Part with the direction of flow.
(2) Clean up the GLASS Inside periodically (including Strainer)
(3) Connect the Measuring Part in Straight Piping Line
( IN Let = 3D ~ 20D Length, OUT Let = 3D ~ 5D Length)
(4) For the repair or cleaning of the Indicator, add the BY Pass function.

5. Troubleshooting
※Prior to install the Flowmeter, Flushing the Piping Line shall be done.
The Strainer is recommended to install in the front of Flowmeter.
Q. Incorrect Buoyant of Rota in Gauge.
A1. Check the Flow first.
A2. In measuring the gas, check the operating pressure with the Flowmeter
Operating Pressure.
< Flowmeter Operating Pressure is called the pressure on the of the Flowmeter>
A3. Check the clogging inside of Body & Indicator to cause the Pressure Loss.
A4. Dismount the Strainer and Clean.
A5. Check the Limit Stopper of Flow.
(Open the Upper CAP, and check the clogging of hole on the Upper Limit Stopper
in Glass.)
Q. Leak between the glass and Connection to BODY.
A1. Check the omission of the seal (packing) between the Indicator and Connection.
A2. Tighten down the Indicator tight bolts
Q. Impossible to read the Flow rate
A1. Open the Upper cover and disassemble the GLASS.
Clean the inside of GLASS with soft cloths or brush.
