Model Vortex PhD™
Inline Vortex Flowmeter
EMCO’s Vortex PhD™ inline vortex flow meters measure a wide variety of fluids and pipe sizes. The fully welded construction
with no internal gaskets eliminates leak paths. Since the sensor is not in the flow, it can be removed without process shut down.
Features
• Reliable–no moving parts,
no fluid to sensor contact
• In-process removable sensor,
below 750 psig (52 barg)
pressure
• Simple, rugged, all welded
construction, no internal
gaskets, no leak paths
• High accuracy with wide
rangeability
• Line sizes from 1 to 12"
(25 to 300 mm)
• High temperature operation
up to 750°F (400°C)
• EZ Logic™ menu-driven user
interface
• ‘Smart’ electronics provide
excellent noise immunity
Superior Flow Measurement Capability
The EMCO Vortex PhD™ vortex shedding flowmeter measures process fluid flow
by detecting the frequency at which vortices are shed from an obstruction in the
process fluid line (the bluff body). A piezo-electric sensor mounted outside the
flow line acts as the transducer, converting vortex pulses into electrical signals.
The ‘Smart’ electronics provide excellent noise immunity while the wide range
of wetted materials provides outstanding compatibility with most process fluids.
The transmitter provides a frequency output, scaled frequency output, totalizer
pulse or a 4 to 20 mA DC signal proportional to the flow rate.

K-factor - Temperature Correction
The K-factor of the flowmeter decreases by 0.29% for each 100°F (39°C) increase in temperature
above 70°F (21°C). The converse is true below 70°F (21°C). By programming the operating fluid
temperature in the electronics, the change in the K-Factor is automatically corrected for.

Notes:
1
Water values are determined at standard conditions of 60°F (15°C).
2
The minimum flow rate for the 1” (25 mm), and 1.5” (40 mm) flowmeters are below the
linear range - the Reynolds number < 20,000.

The velocities used to calculate the minimum and maximum flow rates were 1.5 ft/sec
and 32 ft/sec (0.5 m/sec and 9 m/sec) respectively.

At standard conditions of 60°F and 14.7 psia, SCFH: standard cubic feet per hour (0°C and 1.013 bar, NCMH: Normal cubic meters per hour).
Process temperature is 60°F (16°C).
Maximum flow velocity is 260 ft/sec (79 m/s) or Reynolds number limit or 7,000,000 whichever is less.

Cenelec Approved– Power & Signal Wiring
The Vortex PhD flowmeter may be operated using a 24 VDC power supply. The
wiring schematic shown is for the areas defined by the Cenelec approval (see
approval description in options section). I. S. zener barriers must have the following
specifications:
Vmax =
29 VDC
=
Maximum voltage which may be connected to barrier terminals
Jmax =

=
Maximum current which may be connected to barrier terminals
Cint =

=
Maximum equivalent internal capacitance across barrier terminals
L int =
0H
=
Maximum equivalent internal inductance across barrier terminals
The 4 to 20 mA output is scalable (2 wire principle.) The 4 to 20 mA loop resistor
should be 250 Ω; and the pulse output is to be connected to a high impedance,
electronic counter.

110/220 VAC– Power & Signal Wiring
The Vortex PhD flowmeter may be operated using a 110/220 VAC power supply. The
power supply board converts the 110/220 VAC to 24 VDC. The 4 to 20 mA output is
scalable (2 wire principle.) The 4 to 20 mA loop resistor should be 250Ω; and the
pulse output is to be connected to a high impedance, electronic counter. (Figure 9)
