This instruction manual is an essential component of the Portable
FlowShark Pulse system; therefore, ADS recommends keeping this
manual accessible at all times.

ADS strictly prohibits disabling or altering the function of the
safety devices in any way.

Use in Accordance with the Requirements

The Portable FlowShark Pulse and corresponding sensors are designed for temporary
use in measuring slightly- to heavily-polluted flow in partially-filled and full pipes or
other similar applications. The portable unit also detects and records external data
and supports external peripheral equipment.

While the Portable FlowShark Pulse is primarily designed to receive power from a
rechargeable battery pack, it also can receive power from an independent power
source through the combination power pack/battery charger. The unit stores flow
measurement and other data on a removable memory card.

Please adhere to the measurement specifications designated in this manual.
Monitoring flow under conditions falling outside the documented specifications of the
equipments’ capabilities without prior written permission of ADS occurs at the user’s
risk.

Modifying or using this equipment for purposes other than the
intended use (described above) without the prior written consent of
the manufacturer will be considered outside the specifications of
the equipment. Therefore, any resulting damages that may occur
will be at the user’s risk or expense.

Introduction 1-7

Sensors

Water-Ultrasonic Velocity/Combination Sensor

This sensor is designed to measure flow velocity in slightly- to heavily- polluted
media in partially-filled and full sewers, pipes, and other channels. Some versions of
this sensor can also perform level (i.e., depth) measurement.

Air-Ultrasonic Depth Sensor

This sensor is designed for measuring flow depth from the top of the pipe using
ultrasonic technology.

Mini Water-Ultrasonic Velocity Sensor

This sensor is designed for measuring flow velocity in slightly- to heavily-polluted
media in partially-filled or full pipes and channels exhibiting low depth levels. It
connects to the Portable FlowShark Pulse through the Electronic Box (EBM).
However, it requires an additional level (i.e., depth) measurement.

1-8 ADS Portable FlowShark Pulse Manual

TÜV12ATEX087812.

Mini Air-Ultrasonic Depth Sensor

This sensor is designed for measuring flow level (i.e., depth) from the top of smaller
pipes using ultrasonic technology. This sensor connects to the Portable FlowShark
Pulse through the Electronic Box (EBM).

EBM Electronic Box

The Electronic Box (EBM) is designed for connecting the Mini Water-Ultrasonic
Velocity and Mini Air-Ultrasonic Depth Sensors to the Portable FlowShark Pulse
using independent electronic sensor components.

Please note the maximum permissible limit values specified in Appendix A. The
owner assumes all risk and responsibility for any applications that fall outside these
specifications without the written consent of ADS.

The sensors and the Electronic Box are intended to be used
exclusively for the purposes as described above. Modifying or
using the sensors or Electronic Box for any other purpose without
the prior written consent of the manufacturer will not be
considered as use in accordance with the requirements.
Therefore, any damages resulting from this use will be incurred
at the user’s risk.

The sensors are designed for a lifetime of approximately 10
years. After 10 years, the sensors must undergo an inspection
and a general overhaul.

Ex-Approval

The Ex-version of the sensors is designed for use in areas with explosive atmospheres
(zone 1).

Approval

This approval is valid only in connection with the respective
markings on the sensors’ nameplates.

The Ex-version sensors coincide with the Portable FlowShark
Pulse regarding the assessment of intrinsically safe electrical
systems according to EN 60079-25.

When using other manufacturer’s transmitters, the operator must
assess the system based on EN 60079-25.

Obtain the required specifications for Ex-version sensors from
the EC-type examination certificate TÜV 03 ATEX 2262 or

II 2 G Ex ib IIB T4 Gb

User’s Responsibilities

Obtain all local operating permits required and observe the provisions contained
within the permits. In addition, observe all local laws and regulations concerning the
following:

 Personnel safety (accident prevention regulations)
 Work material and tool safety (safety equipment and maintenance)
 Product and material disposal (laws on wastes)
 Cleaning (cleansing agents and disposal)
 Environmental protection

Before operating this equipment, all personnel involved in installation and/or initial
start-up activities must consider and acknowledge all local regulations, such as those
pertaining to performing operations in sanitary sewer environments.

present in the flow for reflecting the ultrasonic signal sent by the sensor.

System Overview and Operation

The Portable FlowShark Pulse is a portable monitoring system and data storage
device designed for temporary flow measurement in slightly- to heavily-polluted flow
of various compositions in partially-filled to full pipes of various shapes and
dimensions. The system measures flow velocity by spatial allocation using ultrasonic
pulses. Signal evaluation occurs through cross-correlation using a digital signal
processor. Depth measurement occurs through various sensors via ultrasonic (transit­time) technology directed from the top (air) or bottom (water) of the pipe, pressure
measurement cell, or mA input (for external depth measurement).

The method for measurement is based on the ultrasonic reflection
principle. Therefore, to ensure the system operates properly, it is
essential that particles, such as dirt, gas bubbles, or similar objects, are

Water-Ultrasonic Velocity/Combination (Wedge) Sensors

The Portable FlowShark Pulse uses a combination sensor that can simultaneously
determine both flow velocity and flow depth or a standalone velocity sensor. A
combination sensor may contain up to two 2 depth measurement devices: a water­ultrasonic device and a hydrostatic (pressure) device. Two independent piezo crystals
function as transmitter or receiver for taking ultrasonic measurements to determine
flow depth and velocity.

Air-Ultras onic Depth Sensor

ADS offers an air-ultrasonic depth sensor for the Portable FlowShark Pulse that uses
horizontal sensor crystals to determine the distance (range) from the sensor to the
flow surface based on the time difference between transmitting and receiving a pulse
reflected off the flow surface (the transit-time method). The flow depth is calculated
by subtracting the range from the pipe height, while compensating for the sensor
offset.

The air-ultrasonic depth sensor is not effective for depth measurement when the
sensor becomes submerged or depths occur within 4 inches of the sensor crystal,
known as the deadband.
