OPTIONS
A & B: O-Ring Seals |
|
OPTION
N: Ammonia Service |
O-Rings
are used to seal internal flanged joints. Standard
O-Ring material is Buna-N which is suitable
for a wide range of liquids and gases. If
no option is specified, Buna-N will be
furnished. If Buna-N is not satisfactory,
then Viton or
EPR seals may be suitable. See our Recommended
Meter Materials Page for material ratings. Please
consult with us if an appropriate seal
material is not shown. E.I.

This
option includes a brass free construction
throughout, EPR seals, a stainless steel
gear movement and gasketed case. Price
includes calibration to specific gravity,
pressure and temperature compensation. This
option is available for model 73 ONLY
!
|
|
OPTION
C: Calibration for Sp. Gr. |
|
OPTION
P: Panel Mount |
All
Series 7000 Flo-Gages are normally calibrated
for water with a specific gravity of
1.0 (density of 62.4 lbs./ft³). If
fluids of different density are to be
metered, the meter will require either
a correction factor or calibration for
the desired specific gravity. |
|
This
option provides a special meter case for
mounting on panels. This option is
available on 1-1/2" and smaller meters
only. |
|
OPTION
D: Gasketed Meter Housing |
|
OPTION
R: Digital Readout/Totalizer |
Standard
meter housing protects the meter mechanism
against normal dirt and dust. If
the meter is to be exposed to the weather,
marine service, splashing liquids, corrosive
vapors, or extreme humidity or dusty conditions,
then a gasketed meter housing is recommended. Gaskets
of neoprene sponge are installed at the
body flange, back cover plate and under
the dial crystal to make the housing leak-tight. |
|
A
loop power (4-20mA dc) two-wire indicator
displays 4-1/2 digits for flow rate and
8 digits for totalization. Includes
scaled, open collector output for remote
totalizer. Includes square root extraction. Replaces
the standard dial indicator. Requires
our option W3. Click

option. |
|
OPTION
E: Non-Std. Flow Rates |
|
OPTION
R2: Remote
Readout |
Various
full-Scale flow rates are available for
each pipe size as indicated in the chart
of "Standard Flow
Rates and Body Sizes". These
standard flow rates meet nearly all industrial
applications and comply with good engineering
practice in piping design. However,
if smaller flow ranges are necessary,
special orifices can be furnished. Consult
with us if this is a desired option ! |

Adapters
and 3-way equalizing valve (Bronze) provide
extended temperature ranges or remote
mount for more convenient viewing. See here to view picture of Remote Reading Flowmeter

|
OPTION
ES: Low Flow Rates |
|
OPTION
R3: Remote Readout |
A
low flow meter is available with ½" female
NPT connections for measuring the flow
of liquids as low as 1 GPH and gases
as low as 10 SCFH. A minimum inlet pressure of 10
psi is required for
liquids and gases. Accuracy is ±5%
of full scale. |

Adapters
and 3-way equalizing valve (316SS)
provide extended temperature ranges or
remote mount for more convenient viewing. See here to view picture of Remote Reading Flowmeter |
|
Option
G: Custom Scales and Dials |
|
OPTION
T: Expanded Temp. Range |
Non-standard
flow rates and custom dial patterns require
preparation of special artwork and stencils. A
one time charge is made for each custom
dial pattern or non-standard scale. |
|
Materials
suitable for a range of 80F to 350F are
provided. Higher temperatures
available in combination with Option R2. |
|
OPTION
H: 400 psig Service |
|
OPTION
V: Calabrate for High Viscosity Liquids |
Standard
meters are equipped with bellows which
have a service rating of 180 psig maximum. High
strength bellows made of Inconel 718 are
available with service ratings to 400 psig
and may be used where service conditions
permit use of stainless steel. A
slight increase in pressure drop across
the meter results when these bellows are
used. International

Liquids
having high viscosities cause flow meters
to read high; however, this effect is
slight for liquids having viscosities
less than 5 centipoises. Heavy
lubricating and fuel oils with viscosities
up to 500 cps require special sizing
of the flow meter orifice. Flo
Gages are not recommended for metering
of fluids with viscosities greater than
500 centipoises. Consult
with us for specific recommendations. |
|
OPTION
I: Compressed Gas Service |
|
Option
W: Transmitter |
Meters
intended for compressed gas service require
individual sizing of meter orifices to
suit the desired flow rate, gas composition,
line pressure and temperature. In
addition, dials are marked with type of
gas, specific gravity, line pressure and
temperature as part of this option. |

Option
J: Peak Flow Indicator |
|
Option
W2: Transmitter |
A second pointer
is provided with a reset knob to provide
an indication of the maximum flow rate
achieved since reset. |
|
|
|
Option
K: Saturated Steam Service |
|
Option
W3: Transmitter |
The
steam service option includes EPR seals,
SS bellows and inverted housing. Steam
pressures are limited to 120# saturated
unless remote (option
R2) is used. Temperature range: -80° F to 350° F |
