ORIFLO
GENERAL
O series ORIFLO METER is a By-pass Orifice type flowmeter.
Small sized variable flowmeter is installed onto measuring tube part
in which an orifice plate for by-pass flow is integrated.
Three different process connections,i.e., "SCREW", "FLANGE" and
"WAFER", are available for Selection.
An isolation valve is available between measuring tube and indica-
tor for indicator maintenance work even during process operation.
This eliminates the necessity of by-pass piping for maintenance pur-
pose and saves total piping cost.
In addition to standard material of STEEL version, Stainless steel
and PVC versions to cover corrosive fluids are available.
Alarm contacts are available as option. (O-780 series)
FEATURES
❏ LOW COST / HIGH PERFORMANCE
Thanks to unique orifice by-pass system, total instrumentation
cost can be saved especially for medium and large sized piping
measurement.
❏ COMPACT DESIGN
Small sized indicator saves space in plants.
❏ EASY INSTALLATION
"SCREW", "FLANGE" and "WAFER" are ready to meet field re-
quirements.
By-pass piping for maintenance purpose can be skipped by using
isolation valve.
❏ FOR ALL FLOW DIRECTIONS
BOTTOM TO TOP, TOP TO BOTTOM, LEFT TO RIGHT, RIGHT
TO LEFT.
ORIFLO is applicable for all possible flow directions. Change of
such flow direction is possible in field even after installation.
❏ ALARM CONTACT
Besides local flow rate indication, alarm contact (s) are available.
ORIFLO can be used as FLOWSWITCH.
❏ EASY MAINTENANCE
Simple design and limited number of parts saves maintenance
work.
❏ HIGH ANTI CORROSIVE CAPABILITY VERSION
Stainless steel and PVC versions are available for corrosive fluid
application.

By-pass orifice
As shown in the figure, differential pressure is produced across the
Main orifice plate by flow velocity which corresponds to flow rate.
A small sized flowmeter (Variable area flowmeter) is mounted onto
this differential pressure production unit. By this arrangement, the
flow rate through the flowmeter corresponds to the flow rate through
the main piping.
Thus, scale range for main piping can be engraved onto the small
sized flowmeter and the flow rate through the main piping is indicated
by the position of float of the flowmeter.
Normally, an isolation valve is provided between the measuring tube
and the indicator for the purpose of indicator maintenance with no in-
terference of process operation. (This valve is for maintenance/ iso-
lation purpose and not for flow control purpose.)
A magnet piece is buried into the float for Alarm version which at-
tracts reed switch for alarm contact output. The setting point of alarm
is adjustable by shifting the location of reed switch.

Conversion calculation
The calculation of figures in the above flow range table hasbeen made on the premises that SGP, a JIS code name fora carbon steel pipe for ordinary piping, had been used formain pipes. ln case of pipes other than SGP, multiply theabove liquid quantity by (the inner diameter of a pipe used ÷the inner diameter of a SGP pipe)2.
●FOR GAS MEASUREMENTORIFLO for gas flow measurment will be calibrated and graduated according to customers' individual operating conditionsuch as density, pressure and temperature.Refer to ORDERING INFORMATION on page 15 and specify operating condition.The following table is shown by the air flowrate at 0°C,1 atm. Conversion calculation is required in case actual operating condition differs from this.
Q = Q × Cγ × Ct × CpQ : Converted Air flowQ : Flow rate of Actual GasCγ : Cγ = γ /1.293 (γ=Sp, Wt of the Gas, kg/Nm3)Ct : Ct = (273+t)/273 (t=operating temp., °C)Cp: Cp = 0.1013/(0.1013+p) (p=operating press. MPa)

In addition to standard O-180 with Glass tube flowmeter indication, O-190 series Dial indication type is available. Consult
factory for details.
A. Integrated Dial Indication type O-190-DG
O-190-DG indicaters flowrate by pressure gauges. 3 waymanifold valve is provided.
B. 0-190-B ■ separate indication seriesDifferent types of pressure indicators can be used for indication of flow rate. They can be installed separately away fromorifice piping for better observation.

(1) Required straight run upstream and downstream
The following straight run is recommended for accuratemeasurement :
(3) Reading of flow rate
The flow rate is to be read by the position of floatand engraved graduation. Refer to the following :
(2) Air bubble elimination and draining
Air bubble in the indicator may cause measurement error.
Eliminate the air in the indicator through Air elimination
plug at the top of indicator for the start-up.
For liquid application, it is recommended to close the
isolation valve and drain out the liquid in the indicatorthrough drain plug in case the operation of process is
stopped for some reason.
Freezing of the liquid in the tapered tube may causebreakage of tube. Indicator with drain valve is available
on request.
(4) Flow direction
By changing the direction of indicator, ORIFLO may beused for any flow direction of bottom to top, left to right,right to left and top to bottom. This change can beconducted in the field as well.
Ball valves are available for air eliminator and drain outas option as follows ;
