injury.

CAUTION

Indicates a potentially hazardous situation that may result in minor or moderate injury.

N O T I C E

Indicates a situation which, if not avoided, may cause damage to the instrument. Information that requires special

emphasis.

4.1.2 Precautionary labels

Read all labels and tags attached to the instrument. Personal injury or damage to the instrument

could occur if not observed. A symbol on the instrument is referenced in the manual with a

precautionary statement.

This is the safety alert symbol. Obey all safety messages that follow this symbol to avoid potential

injury. If on the instrument, refer to the instruction manual for operation or safety information.

This symbol indicates that a risk of electrical shock and/or electrocution exists.

This symbol indicates the presence of devices sensitive to Electro-static Discharge (ESD) and

indicates that care must be taken to prevent damage with the equipment.

Electrical equipment marked with this symbol may not be disposed of in European domestic or public

disposal systems. Return old or end-of-life equipment to the manufacturer for disposal at no charge to

the user.

This symbol, when noted on the product, identifies the location of a fuse or current limiting device.

This symbol indicates that the marked item requires a protective earth connection. If the instrument is

not supplied with a ground plug on a cord, make the protective earth connection to the protective

conductor terminal.

4.1.3 Confined space precautions

D A N G E R

Explosion hazard. Training in pre-entry testing, ventilation, entry procedures, evacuation/rescue

procedures and safety work practices is necessary before entering confined spaces.

The information that follows is supplied to help users understand the dangers and risks that are

associated with entry into confined spaces.

English 5

On April 15, 1993, OSHA's final ruling on CFR 1910.146, Permit Required Confined Spaces, became

law. This standard directly affects more than 250,000 industrial sites in the United States and was

created to protect the health and safety of workers in confined spaces.

Definition of a confined space:

A confined space is any location or enclosure that has (or has the immediate potential for) one or

more of the following conditions:

• An atmosphere with an oxygen concentration that is less than 19.5% or more than 23.5% and/or a

hydrogen sulfide (H2S) concentration that is more than 10 ppm.

• An atmosphere that can be flammable or explosive due to gases, vapors, mists, dusts or fibers.

• Toxic materials which upon contact or inhalation can cause injury, impairment of health or death.

Confined spaces are not designed for human occupancy. Confined spaces have a restricted entry

and contain known or potential hazards. Examples of confined spaces include manholes, stacks,

pipes, vats, switch vaults and other similar locations.

Standard safety procedures must always be obeyed before entry into confined spaces and/or

locations where hazardous gases, vapors, mists, dusts or fibers can be present. Before entry into a

confined space, find and read all procedures that are related to confined space entry.

4.1.4 EU/FCC/IC/ANATEL regulations

Use of this device is subject to the conditions that follow:

• There are no user serviceable items inside this device.

• The user must install this device in accordance with the supplied installation instructions and must

not modify the device in any manner whatsoever. Any changes or modifications to the device may

void the user’s authority to operate this equipment.

• Any service that includes the transmitter must only be done by Hach Company.

• This device is considered a “mobile” wireless device per the FCC. For RF exposure safety, the

user must maintain a minimum of 20 cm (8 in.) separation distance from the face of the radar

transmitter when it is in operation.

4.2 Certification

CAUTION

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, ICES-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

6 English

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.

4.3 Product overview

The Flo-Dar sensor measures the flow velocity and liquid depth in open channels using radar and

ultrasonic technology. The unit is made to withstand submersion during surcharge conditions. The

optional surcharge velocity sensor supplies velocity measurements during surcharge conditions.

Figure 1 shows the configuration of a Flo-Dar system in a non-hazardous location.

Theory of operation information and ordering information for replacement parts are available in the

expanded user manual on the manufacturer's website (http://www.hach.com).

Section 5 Installation

D A N G E R

Explosion hazard. Trained personnel only must install or commission the equipment.

5.1 Mechanical installation

5.1.1 Site location guidelines

N O T I C E

To prevent damage to the enclosure, install the instrument away from direct sunlight, ultraviolet radiation (UV),

heat sources and severe weather. Install a sun shade or protective cover above the instrument when the location

is outdoors.

For the best accuracy, install the sensor where the flow is not turbulent. The ideal location is in a

long, straight channel or pipe. Outfalls, vertical drops, baffles, curves or junctions cause the velocity

profile to become distorted.

Where there are outfalls, vertical drops, baffles, curves or junctions, install the sensor upstream or

downstream as shown in Figure 4–Figure 6. For upstream locations, install the sensor at a distance

that is at least five times the pipe diameter or the maximum fluid level. For downstream locations,

install the sensor at a distance that is at least ten times the pipe diameter or the maximum fluid level.

If the location contains a junction and the flow in one pipe is much higher, install the sensor on the

wall near the lower flow pipe.

Figure 4 Sensor location near an outfall, vertical drop or baffle

1 Acceptable upstream sensor location 5 Distance downstream: 10 × pipe diameter

2 Outfall 6 Vertical drop

3 Distance upstream: 5 × maximum level 7 Baffle

4 Acceptable downstream sensor location
