Certification
C A U T I O N
This equipment is not intended for use in residential environments and may not provide adequate protection to
radio reception in such environments.
Canadian Radio Interference-Causing Equipment Regulation, IECS-003, Class A
:
Supporting test records reside with the manufacturer.
This Class A digital apparatus meets all requirements of the Canadian Interference-Causing
Equipment Regulations.
Cet appareil numérique de classe A répond à toutes les exigences de la réglementation canadienne
sur les équipements provoquant des interférences.
FCC Part 15, Class "A" Limits
Supporting test records reside with the manufacturer. The device complies with Part 15 of the FCC
Rules. Operation is subject to the following conditions:
1.
The equipment may not cause harmful interference.
2.
The equipment must accept any interference received, including interference that may cause
undesired operation.
Changes or modifications to this equipment not expressly approved by the party responsible for
compliance could void the user's authority to operate the equipment. This equipment has been tested
and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC rules.
These limits are designed to provide reasonable protection against harmful interference when the
equipment is operated in a commercial environment. This equipment generates, uses and can
radiate radio frequency energy and, if not installed and used in accordance with the instruction
manual, may cause harmful interference to radio communications. Operation of this equipment in a
residential area is likely to cause harmful interference, in which case the user will be required to
correct the interference at their expense. The following techniques can be used to reduce
interference problems:
1.
Disconnect the equipment from its power source to verify that it is or is not the source of the
interference.
2.
If the equipment is connected to the same outlet as the device experiencing interference, connect
the equipment to a different outlet.
3.
Move the equipment away from the device receiving the interference.
4.
Reposition the receiving antenna for the device receiving the interference.
5.
Try combinations of the above.
Product overview
The portable velocity system is used in the field, laboratory and municipalities. Turbulent, noisy and
low flows can be measured with this system.
When the sensor is placed in flowing water, a magnetic field around the sensor creates a voltage
proportional to the flow velocity. This voltage amplitude, which represents the rate of water flow
around the sensor, is detected by electrodes in the sensor and processed by the sensor
microprocessor. The processed signal is digitally transmitted through the sensor cable to the portable
meter and the information is shown on the meter display. The system includes a portable meter,
sensor with cable and accessories.
The meter and sensor get velocity information in conduits and streams. These measurements are
important for calibration in municipal wastewater industries, as well as for developing and maintaining
stage discharge relationship curves.
Two types of sensor are available: velocity-only and velocity plus depth. This manual covers both
types of sensors. If information applies to a specified type of sensor, this fact is noted in the text.
