VORTEX FLOWMETER (DELTA FLOWPET)

DATA SHEET

FMR, M

This instrument is a Karman vortex flowmeter capable of

measuring the flow rate of liquid, gas, and vapor. The heavy-

duty detecting section made of stainless steel ensures high

accuracy of the instrument.

FEATURES

1. The total flow and instantaneous flow rate can exter-

nally be selected and monitored.

2. The standard is a rainproof type that can be used out-

doors.

3. Heavy-duty stainless steel main body having the struc-

ture 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 pres-

sure 0.5 MPa (gauge), and the nominal piping diameter

80 mm. How can the minimum flow rate nominal diam-

eter 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,

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 deter-

mine the nominal diameter. For calculating the maxi-

mum flow rate when the temperature and pressure have

ranges, retain the higher temperature and lower pres-

sure. Therefore, the actual maximum flow rate is:

273.15+30

273.15

0.1013

0.1013+0.8

QMax. = 800 ×

×

99m³/h

Therefore, the nominal diameter is 40 mm. For obtain-

ing the minimum flow rate, retain the lower tempera-

ture 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, accord-

ing to interpolation,

0.85

-

0.5

0.4

Qmin = 38+

× (47-

38) 45m³/h

Or the minimum flow rate can be obtained upon calcu-

lating an actual density.

Actual density ρ of air at 20°C and 0.5 MPa is:

1.7-1.5

Qmin = 8+

× (9-

8) 8.3m³/h

1.7

-0.95

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 m³/h and, likewise, at

density of 11, is 38 m³/h. At density of 7.04, therefore,

the minimum flow rate is, according to interpolation,

Transducer integration reading unit

The integration reading is in the same unit system as for flow rate.

<Example> If the flow rate is in “m³/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.)

Transducer correct pulse unit

The present table indicates correct pulse units for volumetric flow rate.

In case of fixed conversion to other than volumetric flow rate such as normal flow rate, refer to Tables A through D.

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

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])

For thermal insulation of piping, we recommend you to

adopt a simplified thermal insulation (without mortar fin-

ish) on the flowmeter mounting section for facilitating dis-

assembly or checkup. This arrangement allows to loosen

flowmeter connecting bolts without breaking the thermal

insulating material covering.

where,

∆P: Pressure loss (MPa)

P₀: Liquid vapor pressure (MPa [abs])

(2) Pulsation

Arrange so connecting

bolts can be loosened

upon removing simplified

thermal insulation material.

Simplified thermal insulation

(convenient if divisible)

If the flowmeter is to be installed on a line where Roots

blower, compressor, or other pulsating pressure generat-

ing instruments are mounted, it may be affected by pulsa-

tion. The allowable pulsating pressure is calculated by:

where,

N: Pulsating pressure (kPa)

ρ: Density (kg/m³)

V: Minimum velocity (m/s)

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 permit-

ted many functions.

Pressing pushbutton enables switching to the follow-

ing 4 display modes.

Wall type

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 di-

vider.

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 correc-

tion

The setting of "Divided value", "Meter coefficient", and "Number of cycle samples" can be changed easily by the operation

on the front panel of this instrument. However, do not change them except when the change is unavoidable, because the

setting has been adjusted to meet the specifications of the flowmeter combined to this instrument.
