DATA SHEET
FMR, M
This instrument is a Karman vortex flowmeter capable of
measuring the flow rate of liquid, gas, and vapor. The heavyduty detecting section made of stainless steel ensures high
accuracy of the instrument.
FEATURES

2. The standard is a rainproof type that can be used outdoors.
3. Heavy-duty stainless steel main body having the structure without moving part ensures high durability
4. It does not impose limitations to its mounting positions.
5. Remotely controllable external output (total pulse or
instantaneous analog) is available.

™Determination of minimum flow rate
In Table D, find a value that is nearest to and lower than
the pressure of gas desired, trace it upward in the same
column, and retain the value at the intersection with the
desired nominal diameter in Table C as minimum flow rate.
If it is necessary to exactly determine a minimum flow rate,
proceed to a calculation in the following manner.
Example 1
Suppose the fluid is air, the temperature 20°C, the pressure 0.5 MPa (gauge), and the nominal piping diameter
80 mm. How can the minimum flow rate nominal diameter be found?
The minimum flow rate at nominal diameter of 80 mm at
air of 0.4 and 0.85 MPa in Table D is, according to Table
C, 47 and 38 m3/h, respectively. At a pressure of 0.5
MPa, therefore, the minimum flow rate is, according to
interpolation,
Qmin = 38+
0.85-0.5
× (47-38)
0.85-0.4
45m3/h
Or the minimum flow rate can be obtained upon calculating an actual density.
Actual density ρ of air at 20°C and 0.5 MPa is:
ρ = 1.293 ×
273.15
0.1013+0.5
×
273.15+20
0.1013
7.04kg/m3
Example 2
Suppose the fluid is carbon dioxide, the temperature 5
to 30°C, the pressure 0.8 to 1.5 MPa, and the maximum
flow rate 800 m3/h (normal). How can the minimum flow
rate and the applicable nominal diameter be found? First
obtain the actual maximum flow rate, and then determine the nominal diameter. For calculating the maximum flow rate when the temperature and pressure have
ranges, retain the higher temperature and lower pressure. Therefore, the actual maximum flow rate is:
QMax. = 800 ×
273.15+30
0.1013
×
273.15
0.1013+0.8
99m3/h
Therefore, the nominal diameter is 40 mm. For obtaining the minimum flow rate, retain the lower temperature and higher pressure.
From Tables C and D, the minimum flow rate at nominal
diameter of 40 mm and pressure of 0.95 MPa is 9 m3/h
or, at pressure of 1.7 MPa, is 8 m3/h. Therefore, according to interpolation,
Qmin = 8+
1.7-1.5
× (9-8)
1.7-0.95
8.3m3/h
Note: If the calculated result has a value below decimal point, truncate it
for maximum flow rate, or round it up for minimum flow rate.
From Table C, the minimum flow rate at density of 6 and
nominal diameter of 80 mm is 47 m 3/h and, likewise, at
density of 11, is 38 m 3/h. At density of 7.04, therefore,
the minimum flow rate is, according to interpolation,
Qmin = 38+

The integration reading is in the same unit system as for flow rate.
<Example> If the flow rate is in “m 3/h”, the integration reading is in “m3”. The number of digits below decimal point is
the same as for correct pulse unit. (If the value of correct pulse is “1” or more, the decimal point will not be
indicated.)

Notes
1. The concept is intended for Sch.40 pipe. Therefore, use Sch.40 pipe as standard.
2. Be sure to provide a straight pipe section of 5D or more downstream.
3. Provide pressure and temperature detectors downstream the flowmeter (figure below).

2. Thermal insulation procedure
For thermal insulation of piping, we recommend you to
adopt a simplified thermal insulation (without mortar finish) on the flowmeter mounting section for facilitating disassembly or checkup. This arrangement allows to loosen
flowmeter connecting bolts without breaking the thermal
insulating material covering.
Arrange so connecting
bolts can be loosened
upon removing simplified
thermal insulation material.

3. Considerations regarding process conditions
(1) Prevention of cavitation
If liquid is used, so that no cavitation will occur, secure a
line pressure higher than calculated by:
P ≥2.60 ∆P+1.25Po (MPa [abs])
where,
∆P: Pressure loss (MPa)
P 0: Liquid vapor pressure (MPa [abs])
(2) Pulsation
If the flowmeter is to be installed on a line where Roots
blower, compressor, or other pulsating pressure generating instruments are mounted, it may be affected by pulsation. The allowable pulsating pressure is calculated by:
N<
Span
6
Arrange so flange tightening
nuts can be loosened.

INTEGRATING METER (Type: FMM)
OVERVIEW
This instrument is a compact type LCD display counter that
receives pulse signal from vortex flowmeter and indicates
total flow and digital instantaneous flow rate (with power
supply for the oscillator built in).
Flush mount type
FEATURES
1. One-chip CPU mounted on this instrument has permitted many functions.
Pressing pushbutton enables switching to the following 4 display modes.
q Total flow, w Zero reset total, e Instantaneous flow
rate (switching between per hour display and per minute
display is possible.), r Meter coefficient
2. This instrument has a function of a scaler and of a divider.
Wall type
3. It converts input pulse signal representing flow rate into
an analog signal through built-in F/I conversion circuit.
(Option)
4. Equipped with pulse output before or after the correction
