INTRODUCTION
The VN2000 Compact Insertion Vortex Flow Meter measures the volumetric flow rate, mass flow rate or BTU/energy of
steam, gas or liquids over a large flow range. The meter is a heavy duty design engineered to stand up to the most abusive
environments inside and outside the pipe.
Principles of Operation
An everyday example of a vortex shedding phenomenon is a flag waving in the breeze: the flag waves due to the vortices
shed by air moving across the flagpole. Within the flow meter, as flowing fluid moves across the tiny strut or “bluff bar”,
vortices are shed on a smaller scale. The frequency of the vortices shedding is proportional to the fluid velocity.
Through the use of an internal RTD, the flow meter software compensates for changes in temperature, to achieve an accurate
mass flow measurement.

Sensors
Figure 2: Vortex shedding
Sensor Operation
Two piezoelectric pressure-sensing crystals are mounted internally in the insertion vortex meter in proximity to the
vortex-generating element, called the shedder bar. Two sensors sense the vortex signals. The crystals convert the pressure
pulses created by the vortices into voltage signals without the need of excitation current or voltage. The sensor crystals are
never in contact with the fluid. The piezo crystals are encapsulated in a stainless steel module.
Calibration Factor
The frequency at which vortices are shed is a linear function of fluid velocity, and therefore, a measure of flow. In the range
covered by the particular flowmeter, vortex frequency is insensitive to specific gravity, viscosity, and temperature of the fluid,
and depends only upon the width (d) in inches and shape of the flow element, and the inside diameter (D) of the pipeline
in inches.
The frequency is F = SV/d
Where:
F = Karman vortex frequency
S = constant (Strouhal Number)
V = fluid velocity at the flow element
D = face width of the element

INSTALLING A VN2000 METER
The Badger Meter VN2000 Insertion Vortex Meter is designed to operate under a wide variety of conditions. To ensure its
longevity of operation, precautions should be taken before and during its installation.
Preinstallation Considerations
Selecting the Installation Site
The meter requires a minimum of 10 straight diameters upstream and 5 straight unobstructed diameters of downstream
piping. One diameter is equal to the internal pipe diameter. This is necessary to ensure regulated formation of vortices.
• Choose a site with minimal mechanical vibrations.
• Do not install the transmitter and cables in close proximity with large transformers, arc-welding equipment, large electric
motors, or similar industrial equipment that emits excessive electromagnetic interference
• Avoid areas of extreme temperature change. The signal conditioner works ideally between temperatures of 32…140° F
(0…60° degrees C ).
• Avoid areas of high humidity or corrosive atmosphere, where possible.
• When installing the meter, choose a site that is accessible and allows ease of wiring and maintenance.
Piping Guidelines
Straight Run Piping Requirements Upstream Pipe Diameters Downstream Pipe Diameters
One 90° elbow before flow meter 10 5
Two 90° elbows before flow meter 15 5
Two 90° elbows out of plane before flow meter 30 5
Reduction before flow meter 10 5
Regulator, valve or header before flow meter 30 5
Tee connection before flow meter 30 5
Table 1: Piping requirements
If the minimum straight run is not possible, install the meter with 80% of the straight run upstream and 20% downstream.
To provide the high accuracy of flow measurement specified on the identification sheet, piping and installation instructions
must be followed carefully.
• The pipe immediately upstream and downstream of the flow meter must be straight, of sufficient length and free of
obstructions. See Table 1 for exact dimensions.
• If recommended piping cannot be found, use straightening vanes on vortex meters.
• Locate any valves downstream of the meter.
• Before installing the meter, make sure nothing (such as weld beads or flange gaskets) protrudes from the internal wall of
the pipe that could interrupt the flow stream and affect the reading.
Temperature Taps
For BTU/Energy Meters: Install temperature transducers in accordance with the manufacturer’s specifications and
2.5…3.5 diameters from the downstream side of the meter body.
Orientation
The VN2000 insertion meter uses dual piezoelectric sensing elements with no moving parts. This eliminates wear and allows
for vertical or horizontal pipe installation. For vertical pipes, the meter can be located in any position.
For horizontal pipe orientations, install the meter above the centerline of the pipe. To prevent condensate from running
into the mounting assembly or pipe assembly, mount the flow meter at 0…80° off of the top center of the pipe. For high
temperature applications, avoid mounting the transmitter over the pipe to keep it out of the path of heat rising from the pipe.
Insulate all pipes surrounding the meter.

Installation Procedure
The flow meter is shipped completely assembled, tested and ready to install and operate in its permanent location.
Prepare the Pipe
These instructions assume the pipe has been fitted with a user-provided Weldolet and the provided mounting assembly
welded over a 1-1/2 in. hole.
1. Make sure the insertion bar is removed from the mounting assembly before welding.
2. Position the 1-1/2 in. Weldolet over a 1-1/2 in. hole in the pipe. Make sure the Weldolet is level to the pipe and the arrow.
3. Weld the Weldolet over the hole. Make sure it is centered exactly over the hole.
4. Insert the mounting assembly into the Weldolet. Turn the mounting assembly until the arrow is pointing directly down the
pipe in the direction of the ow.
5. Tack, then weld the mounting assembly to the Weldolet. Make sure the mounting assembly is welded completely around
into the Weldolet to prevent leaking.
6. Weld the mounting assembly evenly in place over the Weldolet.
MPORTANTI
There is a sensor mounted on the end of the insertion probe. Do not stand the meter on its end. Be careful not to hit or push this end,
or damage to the sensor may occur.

Install the Meter
1. The O-rings on the meter are greased with a non-petroleum product (silicone synthetic grease ONLY). Please check to
see that grease has not been removed due to packing and shipping. If there is minimal grease on O-rings, they must be
re-greased before inserting into mounting assembly. Use at least one to two full packets of high temperature silicone
synthetic grease on the O-rings before inserting the ow meter. Make sure the grease is evenly spread on all around
O-rings and surrounding locations.
2. Insert the probe into the hole in the mounting assembly. Push hard until the meter bottoms out inside the
mounting assembly.
3. Rotate the probe until the notch in the probe aligns with the hole in the mounting assembly. You should see a complete
hole through the mounting assembly before installing the alignment pin.
MPORTANTI
You must make sure the alignment hole is completely clear with no O-rings showing. If O-rings are showing, do not insert the
alignment pin because the pin may cut the O-rings and eventually cause leaking.

4. Rotate the bar until the cutout in the bar lines up with the hole in the mounting assembly and screw down the mounting
assembly nut..
5. Insert the alignment pin completely through the mounting assembly and lock it in place before applying pressure to the
pipe line.
OTE:NThe pin can only be inserted with no pressure in the line and is automatically locked under pressure. This is a safety
feature that eliminates the accidental removal of the pin and the insertion bar under pressure. The mounting
assembly nut will also provide another safety feature that will not allow the meter to come out of the pipe.
When the alignment pin has been inserted, the flow meter finds the precise insertion depth and aligns the vortex element
into the stream of flow.
WIRING A REMOTE TRANSMITTER
To wire remote electronics, use the supplied cable with the multi-pin connectors. The cable is a double-sided, molded
cordset with a single-keyway, threaded connection. The cable ends are the same. See the VN2000 Transmitter user manual for
instructions on installing, wiring and troubleshooting the transmitter.
MPORTANTI
Do not hook up electronics with the power on.
TROUBLESHOOTING
Screen is blank (No display) Verify that you have 24V DC.
Verify that power polarity is correct (Black +24V DC & Blue -24V DC).
Screen shows no flow rate
during flow
Press Menu until you see Low Flow Cutoff. Lower this number until you can see a flow rate.
Check to make sure the arrow in the mounting assembly is pointing down the pipe in the
direction of the flow.
Flow rate is erratic Check to see what is installed upstream of the flow meter. Other instruments or devices
before the flow meter can shed vortices of their own causing a disruption in flow reading.
Check to see what size hole is drilled into the pipe for insertion. If an existing hole larger
than 1.5 inch was used, the larger hole can create turbulence directly above the flow sensor.
Flow rate seems incorrect Review the program settings and make sure the correct line size is chosen for your
application. If this is a multi-variable MASS unit, make sure the correct pressure and
temperature is being displayed on the screen. If this is a fixed MASS unit, make sure the
correct operating pressure is entered into the electronics for calculations.
