2.

Remove the instrument from the plastic packaging and remove the endfitting
protectors from the meter housing.

3.

Visually inspect the entire unit. Any visible damage should be reported to the
OMEGA Customer Service Department immediately.

Replace the end fitting protectors and return the Flowmeter to its plastic
packaging. The unit may thus be stored indefmitely until installed.

INSTALLATION

A. GENERAL PROCEDURE

-

1. Meter Position

FLOWMETERS are normally calibrated in a horizontal attitude.
Best con-elation of calibration, therefore, occurs when installed and operated in
this position. Meters may, however, be operated satisfactorily in any position.

2. Flow Direction

-

ALL PRECISION TURBINE FLOWMETERS are marked “IN”

and “OUT” and have an arrow to indicate the proper direction of the flow.
Directional Flowmeters Excluded)

3. Meter Location
A.

Relative

-

-

When it is expected that flow will be intermittent, the meter should
not be mounted at a low point in the piping system. Solids which settle or
congeal in the meter may affect the meter performances.

B.

Tolerance to Mechanical Vibration

-

Although the PRECISION TURBINE
FLOWMETER is designed for rugged service, meter life may be increased by
location in a minimum vibration area.

C.

Tolerance to Electrical Interference

-

In order to achieve optimum electrical
signal output from the Flowmeter, consideration must be given to its isolation
from ambient electrical interference such as nearby motors, transformers, and
solenoids. (Section IV Maintenance Electrical)

4. System Pressure
A. Minimum Operation Pressure

-

-

A minimum operating pressure should be
maintained to preclude a change in the calibration factor due to various types
of two phase phenomena.

The minimum operating pressure is a function of the
vapor pressure of the fluid and the presence of other dissolved gases.
Maintenance of the system back pressure serves to avoid cavitation of fluid
separation.

1.

General Piping

the

flowmeter engages the angled blades of the turbine rotor.
of the rotor is a function of the fluid velocity and the blade angle engagement.
present in the fluid ahead of the meter can change the effective angle of the engagement

and, therefore, cause a deviation from the supplied calibration (done under controlled
conditions). Proper installation of the Flowmeter minimizes the harmful effects of fluid
swirl.

2.

The Metering Location

following the flowmeter is known as the “THE METERING LOCATION ”. Three typical

metering arrangements are described in the proceeding section of this manual. Each is

designed to minimize fluid swirl. A flow straightener is also shown and should be used

where installation does not allow the otherwise straight run of pipe upstream of the meter.

PLEASE NOTE:
the minimum distances between piping components that are recommended to eliminate
flow disturbances.

3. Meter-by-Pass
a valved by-pass around the Flowmeter. However, the by-pass connections are not to be
placed within the recommended metering run.

4.

Line Purge

foreign materials prior to installing the instrument.
