Rosemount™ 8600 MultiVariable™ Vortex reduces
installation costs, simplifies installation, and improves
performance in saturated steam

Multivariable vortex design

Incorporates temperature sensor into the vortex meter using
the shedder bar as a thermowell, which keeps the temperature
sensor isolated from process for easy verification and
replacement.

Temperature compensated capability for
saturated steam

Calculates density from measured process temperature and
uses the calculated density to provide a temperature
compensated mass flow.

Increased performance in saturated steam

Performance in saturated steam is improved due to the fact that
the electronics will be compensating for changes in the process
temperature.

Reduces installed costs

MultiVariable vortex eliminates the need for an external
thermowell and temperature sensor.

Output options

Remote mount electronics

Also available with remote mounted electronics up to 75 ft.
(23 m).

When you integrate the Multivariable vortex with a Rosemount
Flow Computer, you get:

 Remote communications

 Heat calculations

 Remote totalization

 Peak demand calculation

 Datalogging capabilities

For more information on the Rosemount Flow Computer, see
the Rosemount Flow Computer Product Data Sheet

.

Can map independent variables to analog output, pulse output,

®

or HART

burst variables.

Available with flow computer for additional
functionality

Integrate the Multivariable vortex with a pressure transmitter
for full pressure and temperature compensation of superheated
steam and various gases.

Analog output adjustment

Engineering units and lower and upper range values are
user-selected. Output is automatically scaled to provide 4 mA at
the selected lower range value, 20 mA at the selected upper
range value. No frequency input is required to adjust the range
values.

Scalable frequency adjustment

The scalable pulse output can be set to a specific velocity,
volume, or mass (i.e. 1 pulse = 1 lb). The scalable pulse output
can also be scaled to a specific rate of volume, mass, or velocity
(i.e. 100 Hz = 500 lb/hr).

Ambient temperature limits

–58 to 185 °F (–50 to 85 °C)
–4 to 185 °F (–20 to 85 °C) for flowmeters with local indicator

42 Vdc terminal voltage (with 250-ohm minimum load required
for HART communications, 16.8 Vdc power supply is required).

Power consumption

Permanent pressure loss

The approximate permanent pressure loss (PPL) from the
Rosemount 8600 Flowmeter is calculated for each application in
the Vortex sizing software available from your local Rosemount
representative. The PPL is determined using the equation:

Minimum upstream pressure (liquids)

Flow metering conditions that would allow cavitation, the
release of vapor from a liquid, should be avoided. This flow
condition can be avoided by remaining within the proper flow
range of the meter and by following appropriate system design.

For some liquid applications, incorporation of a back pressure
valve should be considered. To prevent cavitation, the
minimum upstream pressure should be:

P = 2.9P + 1.3p

or P = 2.9P + pv + 0.5 psia (3.45

v

kPa) (use the smaller of the two results)

P = Line pressure five pipe diameters downstream of the

meter (psia or kPa abs)

P = Pressure loss across the meter (psi or kPa)

p

= Liquid vapor pressure at operating conditions (psia or

v

kPa abs)

Failure mode alarm

HART analog

If self-diagnostics detect a gross flowmeter failure, the analog
signal will be driven to the following values:

Signal Value

High or low alarm signal is user-selectable through the fail mode
alarm jumper on the electronics. NAMUR-compliant alarm limits
are available through the C4 or CN Option. Alarm type is field
configurable also.

Saturation output values

When the operating flow is outside the range points, the analog
output continues to track the operating flow until reaching the
saturation value listed below; the output does not exceed the
listed saturation value regardless of the operating flow.

The NAMUR-Compliant Saturation Values are available through
the C4 or CN option. Saturation type is field configurable.

Saturation Value

Low 3.9

High 20.8

NAMUR Low 3.8

NAMUR High 20.5

Damping

Flow Damping adjustable between 0.2 and 255 seconds.

Process Temperature Damping adjustable between 0.4 and

32.0 seconds (MTA Option Only).

Response time

Three vortex shedding cycles or 300 ms, whichever is greater,
maximum required to reach 63.2% of actual input with the
minimum damping (0.2 seconds).

Turn-on time

HART analog

Less than four (4) seconds plus the response time to rated
accuracy from power up (less than 7 seconds with the MTA
Option).

Transient protection

The optional transient terminal block prevents damage to the
flowmeter from transients induced by lightning, welding, heavy
electrical equipment, or switch gears. The transient protection
electronics are located in the terminal block.

Low 3.75

High 21.75

Security lockout

When the security lockout jumper is enabled, the electronics
will not allow you to modify parameters that affect flowmeter
output.

Output testing

Current source

Flowmeter may be commanded to set the current to a specified
value between 4 and 20 mA.

Frequency source

Flowmeter may be commanded to set the frequency to a
specified value between 0 and 10000 Hz.

Low flow cutoff

Adjustable over entire flow range. Below selected value, output
is driven to 4 mA and zero pulse output frequency.

Humidity limits

Operates in 0–95% relative humidity under noncondensing
conditions (tested to IEC 60770, Section 6.2.11).

Overrange capability

HART analog

Analog signal output continues to 105 percent of span, then
remains constant with increasing flow. The digital and pulse
outputs will continue to indicate flow up to the upper sensor
limit of the flowmeter and a maximum pulse output frequency
of 10400 Hz.

Flow calibration

Meter bodies are flow-calibrated and assigned a unique
calibration factor (K-factor) at the factory. The calibration factor
is entered into the electronics, enabling interchangeability of
electronics and/or sensors without calculations or compromise
in accuracy of the calibrated meter body.

Notes

The Rosemount 8600 measures the volumetric flow under operating conditions (i.e. the actual volume at the
operating pressure and temperature—acfm or acmh), as shown above. However, gas volumes are strongly dependent
on pressure and temperature. Therefore, gas quantities are typically stated in standard or normal conditions (for
example: SCFM or NCMH). (Standard conditions are typically 59 °F and 14.7 psia. Normal conditions are typically 0 °C
and 1 bar abs.)
The flow rate limits in standard conditions are found using the equations below:
Standard Flow Rate = Actual Flow Rate X Density Ratio
Density Ratio = Density at Actual (Operating) Conditions/Density at Standard Conditions
