INDICATING FLOWRATOR METERS
Electrical Specifications for Alarms
The Fischer & Porter Series VA Master Flowrator
meter is a glass tube variable-area flowmeter
providing visual indication of flow rate over a 12-1/2 to
1 range on a linear scale. Seals in the meter can be
either O-ring or packing gland type to suit the
application.
Contact Rating: Max. 250V; Max. 4A; Max. 500VA
Supply Voltage: 120V ac 15%, 45-65 Hz
Sensor Switch Cable:
Standard - 6.5 feet
Optional - up to 980 feet
Safety Classification: The sensor(s) is intrinsically safe
for Class I, Div. 1, Group A, B, C & D and Class II, Div.
1, Group E, F & G when connected with control amplifier mounted in non-hazardous location.
With either type of seal, the glass meter tube can be
removed easily for range change or cleaning, without
disassembling the end fittings or removing the meter
from the line. Both types have the same external
dimensions and are interchangeable with regard to
piping assembly. Also available with one or two
bistable alarms to give contact closure (or opening) on
rising or falling flow.
Service Conditions
Applications: Glass tube meters are not recommended
for continuous service on alkalis above 100F (38C)
or more than 20% concentrations; nor for fluorine, hydrofluoric acid, water above 200F (93C), steam, slurries, or molten metal.
Universal threaded process connections allow the
meter to be installed with either horizontal or vertical
piping arrangements. Screw-on flanges provide the
maximum in versatility.
Temperature Ratings: Minimum recommended process
fluid temperature is 32F (0C). Maximum recommended process fluid temperature is 250F (121C).
Ambient Temperature Range: 32F to 140F
The meter is available in tube sizes from 1/2-inch
through 2-inch bore for liquid or gas service.
Dimensions meet ISA Standard RP 16.1.2.3.
Pressure Ratings: (In accordance with I.S.A. RP 16.1)
Engineering Specifications
Repeatability: 0.5% of full scale.
Tube Size (inches)
Accuracy: Standard is 2% of maximum flow.
Calibrated standard is 1% of maximum flow.

Meter Sizing
WARNING
For sizing flowmeters when the required flow is of liquid
(density 1.0 g/mL), or of gas (sp. gr. of air and at 14.7 psia
and 70F or 101.3 kPa abs and 21C) the capacity table
may be entered directly.
These meters must not be operated without the operator
protection shield in place. To do so could result in injury to
personnel.
The conversion equations shown permit the capacity
tables to be used for other operating conditions, and
apply to all Capacity Tables shown with Type 316 Stainless Steel Floats.
Accessories
Liquid Conversion
Alarms: One or two* bi-stable alarm switches,
adjustable over entire scale length to give contact
closure (or opening) upon rising or falling flow.
Available with SPDT or DPDT switch action.

Note: Standard percent scales are not applicable to low pressure drop floats.
Notes:
1. Pressure drop is total pressure loss across the meter at100% flow rate in inches of water column.
2. Meter is unaffected by viscosity when the value of cps/ r
(using r = operating density in g/cc and cps = viscosity in centipoises) is less than V.I.C. (viscosity
immunity ceiling). V.I.C. is applicable to liquids only; all gas flows fall below Viscosity Immunity Ceiling.
3. Meters are not recommended for gas service where pressure is below minimum shown. A flow throtting valve close coupled to meter outlet is recommended for
all gas applications.

Note: 1. Pressure drop is total pressure loss across the meter at 100% flow rate in inches of water column.
2. Meter is unaffected by viscosity when the value of cps/r using r = operating density in g/cc and cps = viscosity in centipoises)
is less than V.I.C. (viscosity immunity ceiling). V.I.C. is applicable to liquids only; all gas flows fall below Viscosity Immunity
Ceiling.
3. Meters are not recommended for gas service where pressure is below minimum shown. For such applications use low pressure
drop capacity table. A flow throtting valve close coupled to meter outlet is recommended for all gas applications.
4. Unless other shown, Range is equal to or greater than 12.5:1
5. Short Range Floats; BL-954 is 8:1; BL-953 is 3.5:1; BL-950 & Bl-951 are 3:1.

Note: 1. Pressure drop is total pressure loss across the meter at 100% flow rate in inches of water column.
2. Meter is unaffected by viscosity when the value of cps/r using r = operating density in g/cc and cps = viscosity in centipoises)
is less than V.I.C. (viscosity immunity ceiling). V.I.C. is applicable to liquids only; all gas flows fall below Viscosity Immunity
Ceiling.
3. Meters are not recommended for gas service where pressure is below minimum shown. For such applications use low pressure
drop capacity table. A flow throtting valve close coupled to meter outlet is recommended for all gas applications.
4. Unless other shown, Range is equal to or greater than 12.5:1
5. Short Range Floats; BL-954 is 8:1; BL-953 is 3.5:1; BL-950 & Bl-951 are 3:1.
