Chapter 1 Introduction
SonoPro®Ultrasonic Flow Meters
The VorTek Instruments’ SonoPro®Seriesultrasonic flow meters provide a reli-
able solution for process flow measurement. From the externally mounted trans-
ducers, volumetric flow can be calculated non-invasively.
Multi-Parameter Mass Flow Meters
Mass flow can be determined by using the volumetric flow reading from
the clamp on ultrasonic transducers and measurements from the external
temperature sensors.
Volumetric Flow Meters
The primary sensing elements of the volumetric flow meter are the clamp
on ultrasonic sensors. The analog 4-20 mA output signals offer your
choice of volumetric or mass flow rate. Mass flow rate is based on a
constant value for fluid density stored in the instrument’s memory.
Both the mass and volumetric flow meters come standard with a local
keypad/display which provides instantaneous flow rate, total, and process
parameters in engineering units. A pulse output signal for remote totali-
zation and frequency output are also available. SonoPro®digital elec-
tronics allows for easy reconfiguration for most liquids. The VorTek Se-
ries SonoPro®Meters’ simple installation combines with an easy-to-use
interface that provides quick set up, long term reliability and accurate
volume or mass flow measurement over a wide range of flows, pressures,
and temperatures.

How the SonoPro®Flow Meter Operates
Velocity Measurement
The SonoPro®Fixed Mount flow meter operates on the transit time ultra-
sonic measurement method. This type of measurement uses the basic fact
that the fluid's velocity influences the transmission speed of the ultrason-
ic signal. This is analogous to a person paddling a canoe with the current
versus paddling against the current. The canoe can travel downstream
with the current faster than it can be paddled back upstream against the
current. The same is true for the sound waves as they travel with and
against the direction of fluid flow.
For the measurement, two ultrasonic transducers are mounted
onto the outside of the pipe. With one being downstream at a designated
distance from the other. The electronics send two pulses through the
pipe and into the fluid inside the pipe. One signal is sent with the direc-
tion of the flow, and the second is sent against the flow. The transducers
act as both transmitters and receivers. The transit time of the ultrasonic
signal moving in the direction of the flow is faster than that sent against
the flow. The meter's electronics read these two times and calculate the
time difference, ΔT, which can then be used to determine the average
flow velocity.
The SonoPro®Professional Series electronics take into account the fluid
flow profile and apply a correction to the velocity reading to determine
the average flow through the pipe.
Ultrasonic Flow Path

Temperature Measurement
SonoPro®flow meters can use external 1000-ohm platinum resistance tem-
perature detectors (PRTD) to measure transducer temperature and to adjust
for changes in the speed of sound due to temperature changes.
Flow Meter Configurations
SonoPro®Ultrasonic flow meters are available with different
transducer frequencies for a wide variety of applications. Typi-
cal pipe sizes for each transducer type are listed below.
•2 MHz transducers –1/2” (15mm) pipe to 4” (100mm) pipe typical
•1 MHz transducers –2” (50mm) pipe to 20” (500mm) pipe typical
•.5 MHz transducers –12” (300mm) pipe to 200”(5000mm) pipe
typical
Installation and startup are covered in the following chapters.
Multivariable Options
The SonoPro®meter is available with the following options:
V, volumetric flowmeter; VER velocity and external RTD; VERER, ve-
locity, two external RTDs.
Line Size / Materials
The SonoPro®meter can be applied to line sizes from ½-inch (15mm) to
200-inch (5000mm), in a variety of materials and liners. The SonoPro®
meter comes preloaded with 22 pipe materials and six liner materials. If
the preloaded selections do not cover the intended application, a new
pipe or liner material can be entered pending the speed of sound of the
material is known.
Flow Meter Electronics
The SonoPro®flow meter electronics housing may be used indoors or
outdoors, including wet environments. It can be powered by either AC
(100-240 VAC, 50-60 Hz) or DC (16-36 VDC), with the nominal DC in-
put being 24 Volts. Note: the flow meter will not be damaged if both AC
and DC power is connected simultaneously.
As part of the standard product offering, two analog output signals are
available to output any of the five process variables: mass flow rate, vol-
umetric flow rate, energy flow rate, temperature, or fluid density. A pulse
output signal for remote totalization and a scalable frequency output are
also available. USB communication is standard whereas Bluetooth®,
MODBUS, and BACnet communications are available only as options.
Flow meters include a local 2 x 16-character LCD display housed within
the enclosure. Local operation and reconfiguration are accomplished us-
ing a tactile keypad. If local operation and reconfiguration are not de-
sired, an Android® tablet with VorTek Instruments’ SonoConfig™ In-

Series S36 Instruction Manual Chapter 1 Introduction

strument Interface Software can be purchased to communicate with the
SonoPro®and provide valuable setup, diagnostic, and data logging tools.
The electronics include nonvolatile memory that stores all configuration
information. The nonvolatile memory allows the flow meter to function
immediately upon power up, or after an interruption in power. All flow-
meters are configured for the customer’s flow application.

Chapter 2 Installation
Installation Overview
VorTek’s SonoPro®Ultrasonic flow meter installations are simple and
straightforward. Wiring instructions begin on page 2-20.
Flow Meter Installation Requirements
Before installing the flow meter, verify the installation site allows for the fol-
lowing considerations:
1. Line temperature will not exceed the flow meter rating.
2. The location meets the required minimum number of pipe diameters
upstream and downstream of the sensor head as illustrated in Table
2-1.
3. Safe and convenient access with adequate clearance for mainte-
nance purposes.
4. The degree of protection of at least IP66 to EN 60529 is only
achieved if certified cable entries are used that are suitable for
the application and correctly installed. Unused apertures shall
be closed with suitable blanking elements (e.g., plugs).
Also, before installation check your flow system for anomalies such as:
•leaks
•valves or restrictions in the flow path that could create disturbances
in the flow profile that might cause unexpected flow rate indications
Warning!
Consult the flow meter nameplate for
specific flow meter approvals before any
hazardous location installation.

Series S36 Instruction Manual Chapter 2 Installation
800120 2-2
Unobstructed Flow Requirements
Select an installation site that will minimize possible distortion in the flow
profile. Valves, elbows, control valves and other piping components may
cause flow disturbances. Check your specific piping condition against the ex-
amples shown below. To achieve accurate and repeatable performance, in-
stall the flow meter using the recommended number of straight run pipe di-
ameters upstream and downstream of the sensors.
Note: For liquid applications in vertical pipes, avoid installing with flow in
the downward direction because the pipe may not be full at all points.
Choose to install the meter with flow in the upward direction if possible.

Series S36 Clamp-On Flow Meter Installation
Prior to installing the SonoPro®transducers, a clean pipe surface needs to be
established. Remove any rust or loose paint or debris to make a smooth sur-
face. Choose a section of sound conducting pipe for installing the transduc-
ers. The application should be checked to ensure that air bubbles and particu-
late are at a minimum.
Transducer Mounting Methods
There are three typical mounting methods available. These include the Z
method, which is a single traverse across the pipe, the V method, which is
two traverses across the pipe, and the W method, which is 4 traverses across
the pipe. Each method has its own merits. The V method is by far the most
common for most applications from 4-inch to 12-inch pipe. The W method is
used for smaller pipes, i.e. line sizes ½-inch to 4-inch. The Z method is used
when there is poor signal strength or on pipes larger than 12-inch.

Once the installation method is chosen, you will then need to refer to Chapter 3
for programming the unit for the actual application. The meter will calculate the
appropriate distance to mount the transducers from the data provided. The trans-
ducers can then be mounted to the pipe using the mounting clamps or rail/fixture
system.
