Warnings and Cautions
Warning!
Agency approval for hazardous location installations varies between flow meter models.
Consult the factory for specific flow meter approvals before any hazardous location instal-
lation. For explosion proof installations, you must use solid metal conduit and follow
NFPA (or your local code) approved wiring methods.
Hot tapping must be performed by a trained professional. U.S. regulations often require a
hot tap permit. The manufacturer of the hot tap equipment and/or the contractor perform-
ing the hot tap is responsible for providing proof of such a permit.
All flow meter connections, isolation valves and fittings for cold/hot tapping must have the
same or higher pressure rating as the main pipeline.
For Model M23 insertion flow meter installations, an insertion tool must be used for any
installation where a flow meter is inserted under pressure greater than 50 psig.
To avoid serious injury, DO NOT loosen a compression fitting under pressure.
All wiring procedures must be performed with the power Off.
Before attempting any flow meter repair, verify that the line is de-pressurized.
Always remove main power before disassembling any part of the mass flow meter.
Caution!
Calibration must be performed by qualified personnel. VorTek Instruments, Inc., strongly rec-
ommends that you return your flow meter to the factory for calibration.
In order to achieve accurate and repeatable performance, the flow meter must be in-
stalled with the specified minimum length of straight pipe upstream and downstream of
the flow meter’s sensor head.
When using toxic or corrosive gases, purge the line with inert gas for a minimum of four
hours at full gas flow before installing the flow meter.
Wafer-style flow meter gaskets must be carefully aligned to ensure accurate flow meas-
urement.
For Model M23 insertion flow meter installations, the sensor alignment pointer must point
downstream in the direction of flow.

Chapter 1 Introduction
Pro-V™ Vortex Flow Meters
The VorTek Instruments’ Model M22 In-Line and the Model M23 Inser-
tion Pro-V™ Vortex Flow Meters provide a reliable solution for process
flow measurement. From a single entry point in the pipeline, Pro-V me-
ters offer precise measurements of mass or volumetric flow. The velocity
sensor reduces the effects of pipeline vibration by incorporating a unique
piezoelectric element that senses the vortex frequency. To extend range-
ability at the low end of flow, the meter’s smart electronics calculates the
Reynolds number (Re) based on constant values of fluid density and vis-
cosity stored in memory and automatically corrects for any non-linearity
down to Re = 5,000.
Pro-V digital electronics allows reconfiguration for most gases, liquids
and steam. The instrument is loop powered (12 to 36 VDC) with two
output signals. The pulse output signal is proportional to volumetric flow
rate; the analog linear 4-20 mA signal offers your choice of volumetric
flow rate or mass flow rate. The mass flow rate is based on a constant
value for fluid density stored in the instrument’s memory. The local key-
pad/display provides instantaneous flow rate in engineering units or to-
talized flow.
The VorTek Model M22 and M23 Pro-V Meters simple installation
combines with an easy-to-use interface that provides quick set up, long
term reliability and accurate flow measurement over a wide range of
flows and conditions.

Receipt of System Components
When receiving a VorTek flow meter, carefully check the outside pack-
ing carton for damage incurred in shipment. If the carton is damaged, no-
tify the local carrier and submit a report to the factory or distributor. Re-
move the packing slip and check that all ordered components are present.
Make sure any spare parts or accessories are not discarded with the pack-
ing material. Do not return any equipment to the factory without first
contacting VorTek Customer Service.
Technical Assistance
If you encounter a problem with your flow meter, review the configura-
tion information for each step of the installation, operation and set up pro-
cedures. Verify that your settings and adjustments are consistent with fac-
tory recommendations. Refer to Chapter 4, Troubleshooting, for specific
information and recommendations.
If the problem persists after following the troubleshooting procedures
outlined in Chapter 4, contact VorTek Instruments, Technical Support at
[phone] or [phone] between 8:00 a.m. and 5:00 p.m.
MST. When calling Technical Support, have the following information
on hand:
•the flow range, serial number and VorTek order number (all
marked on the meter nameplate)
•the problem you are encountering and any corrective action
taken
•application information (gas, pressure, temperature and pip-
ing configuration)

How the Pro-V Vortex Flow Meter Operates
Figure 1-1. Model M22 In-Line Vortex Flow Meter
VorTek Model M22 and M23 Pro-V™Vortex Flow Meters use a unique
velocity sensor head to monitor volumetric flow rate. The built-in flow
computer calculates mass flow rate based on a constant value of fluid
density stored in the instrument’s memory. To measure fluid velocity,
the flow meter incorporates a bluff body (shedder bar) in the flow
stream, and the velocity sensor measures the frequency of vortices cre-
ated by the shedder bar. The velocity sensor head is located downstream
of the shedder bar within the flow body.
Velocity Measurement
The Pro-V vortex velocity sensor is a patented mechanical design that
minimizes the effects of pipeline vibration and pump noise, both of which
are common error sources in flow measurement with vortex flow meters.
The velocity measurement is based on the well-known Von Karman vor-
tex shedding phenomenon. Vortices are shed from a shedder bar, and the
vortex velocity sensor located downstream of the shedder bar senses the
passage of these vortices. This method of velocity measurement has many
advantages including inherent linearity, high turndown, reliability and
simplicity.

Chapter 1 Introduction Model M22/M23 Instruction Manual
Vortex Shedding Frequency
Von Karman vortices form downstream of a shedder bar into two distinct
wakes. The vortices of one wake rotate clockwise while those of the
other wake rotate counterclockwise. Vortices generate one at a time, al-
ternating from the left side to the right side of the shedder bar. Vortices
interact with their surrounding space by over-powering every other
nearby swirl on the verge of development. Close to the shedder bar, the
distance (or wave length) between vortices is always constant and meas-
urable. Therefore, the volume encompassed by each vortex remains con-
stant, as shown below. By sensing the number of vortices passing by the
velocity sensor, the Pro-V™Vortex Flow Meter computes the total fluid
volume.

Vortex Frequency Sensing
The velocity sensor incorporates a piezoelectric element that senses the
vortex frequency. This element detects the alternating lift forces pro-
duced by the Von Karman vortices flowing downstream of the vortex
shedder bar. The alternating electric charge generated by the piezoelec-
tric element is processed by the transmitter’s electronic circuit to obtain
the vortex shedding frequency. The piezoelectric element is highly sensi-
tive and operates over a wide range of flows, pressures and temperatures.
