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.
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 (H
2
S) 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.
English
5
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.
Product overview
The submerged area velocity (AV) sensor is used with Sigma flow meters, FL series flow loggers and
AS950 samplers to measure the flow rate in open channels. Refer to Figure 1.
The sensor is available in oil-filled and non-oil-filled versions. The non-oil sensor is used for
reasonably clear sites, or sites where the pipe may become dry. The oil-filled sensor is used for sites
with high levels of biological growth, grit or silt.
Note: Do not use an oil-filled sensor in a pipe that may become dry.
The submerged AV sensor connects to a FL series flow logger or AS950 sampler through an
AV9000 interface module. Refer to Replacement parts and accessories on page 19 to identify the
applicable AV9000 model for the flow logger or sampler.
Note: The submerged AV sensor connects directly to Sigma flow meters. An AV9000 interface module is not
necessary.

Theory of operation
The sensor operates as an area velocity sensor and follows the continuity equation.
Flow rate = wetted area x average velocity
6
English
A pressure transducer in the sensor converts the pressure of the water to a level measurement. The
level measurement and the user-entered channel geometry are used to calculate the wetted area of
the flow stream.
The sensor also contains two ultrasonic transducers: one is a transmitter and the other is a receiver.
A 1 MHz signal is transmitted and reflected off of particles in the flow stream. The reflected signal is
received and its frequency is offset by the Doppler shift proportional to the velocity of the particles in
the flow stream. The flow logger converts the doppler shift in the returned ultrasound signals to a
velocity measurement.

Installation
Installation guidelines
D A N G E R
Explosion Hazard. The non-IS AV sensors (770xx-xxx P/Ns) are not rated for use in classified Hazardous
Locations. For classified Hazardous Locations, use IS AV sensors (880xx-xxx PNs) installed per the control
drawings in 911/940 IS Blind Flow Meter manuals.
D A N G E R
Potential confined space hazards. Only qualified personnel should conduct the tasks described in this section of
the manual.
Do not install more than one sensor in pipes with a diameter of less than 61 cm (24 inches).
Multiple sensors in smaller pipes can create turbulent or accelerated flows near the sensors, which
may cause inaccurate measurements.
Mount the sensor as close as possible to the bottom of the pipe invert. This will give the most
accurate low-velocity-level measurements.
Do not monitor flows in the manhole invert. The best location for the sensor is 3 to 5 times the
sewer diameter/height upstream of the invert.
Put monitoring sites as far from inflow junctions as possible to avoid interference caused by
combined flows.
English
7
Objects such as rocks, pipe joints, or valve stems create turbulence and generate high-speed
flows near the object. Make sure the area 2 to 4 pipe diameters in front of the sensor installation is
clear of obstructions. Best accuracy is obtained when there are no flow disruptions within 5 to
10 pipe diameters.
Do not use sites with low-velocity flows that create silt buildup in the invert or channel. Buildup of
silt near the sensor can inhibit the Doppler signal and cause inaccurate sensor readings and depth
measurements.
Do not use sites with deep rapid flows where sensor installation would be difficult or dangerous.
Do not use sites with high-velocity, low-depth flows. Splash-over and excessive turbulence around
the sensor can cause inaccurate data.
Interference
The AV9000 interface module includes a sensitive radio-frequency receiver capable of the detecting
very small signals. When connected to a flow logger or sampler communications or auxiliary power
ports, some line-powered equipment can add electrical noise that interferes with Doppler velocity
measurements. Interference with measurements is uncommon in typical sites.
The AV9000 is most sensitive to noise falling within its Doppler analysis span of 1 MHz ± 13.3 kHz.
Noise at other frequencies typically does not cause interference.
Some laptop computers can cause interference problems when operated from external AC power
adapters. If such a device has an effect on the measurements, operate the laptop computer with
batteries or disconnect the cable between the laptop computer and the flow logger or sampler.
Install the AV9000 interface module
The submerged AV sensor connects to a FL series flow logger or AS950 sampler through an
AV9000 interface module. Refer to Replacement parts and accessories on page 19 to identify the
applicable AV9000 interface module for the flow logger or sampler.
Note: The submerged AV sensor connects directly to Sigma flow meters. An AV9000 interface module is not
necessary.
1. Install the AV9000 interface module. Refer to the AV9000 documentation for instructions.
2. Connect the sensor cable to the AV9000 interface module. Refer to the AV9000 documentation
for instructions.
3. Connect the AV9000 cable to a sensor port (or terminal) on the flow logger or sampler. Refer to
the flow logger or sampler documentation for instructions.

Zero level calibration
If one or more of the statements that follow are correct, do a zero level calibration before the sensor
is installed.
The installation location is a dry channel.
It is not possible to get an accurate level in the flow because the level changes too rapidly.
It is not possible to get an accurate level in the flow because of physical hazards.
Note: The sensor is factory-calibrated for the specified range and temperature.
Zero level calibration (FL series flow logger or sampler)
To do a zero level calibration with an FL900 flow logger, do a zero level calibration (zero calibration
in air) with the FSDATA Desktop Setup Wizard. Refer to the FSDATA Desktop documentation for
instructions. As an alternative, do a manual zero level calibration (zero calibration in air) with
FSDATA Desktop.
To do a zero level calibration with the FL1500 flow logger or sampler, refer to the FL1500 flow logger
or sampler documentation for instructions. As an alternative, do a zero level calibration with the
FSDATA Desktop Setup Wizard when the sensor is connected to an FL1500 flow logger.
Make sure that the sensor is out of the water and on a flat, level, horizontal surface.
Note: If the sensor is replaced, removed for maintenance or moved to another instrument, do a zero level
calibration.
10
English
Zero level calibration (Sigma 910 to 950 flow meters)
Do a zero level calibration as follows:
Note: If the sensor is replaced, removed for maintenance or moved to another instrument, do a zero level
calibration again.
1. Connect the flow meter to a computer with InSight software. Refer to the flow meter
documentation for instructions.
2. Start the InSight software on the computer.
3. Select Remote Programming.
4. From the Real Time Operations list, select the level sensor.
5. Remove the probe from the liquid and place the sensor flat on the tabletop or floor with the
sensor (the plate with holes) face down.
6. Push OK on the dialog box when complete.
Attach the sensor to the mounting band
Mounting bands have pre-drilled holes for direct mounting of the sensor to the band. Refer to the
steps and the figures to mount the sensor on the mounting band.
Note: If the sensor is the oil-filled type, make sure the sensor is filled with oil before mounting the sensor to the
mounting band. Refer to the Fill sensor oil section of this manual.
1. Attach the sensor to the spring ring (Figure 6). Mount the sensor so that the pressure transducer
extends past the edge of the ring.
2. Route the cable along the edge of the band (Figure 6).
3. Use nylon-wire ties to fasten the cable to the mounting band.
The cable should exit the tied area at or near the top of the pipe.
Note: If a large amount of silt exists in the bottom of the pipe, rotate the band until the sensor is out of the silt
(Figure 8 on page 14). Make sure the sensor remains below the minimum expected water level at all times.
Silt must be measured frequently but not disturbed.

Place the sensor and mounting band in the pipe
1. Position the sensor in the flow. Figure 7 shows a standard upstream configuration, a standard
downstream configuration and a downstream sensor-reversed configuration.
To help determine the best configuration for the site, refer to Table 1. For more information on
configurations, refer to the appropriate logger manual.
2. Slide the mounting band inside the pipe as far as possible to prevent drawdown effects near the
end of the pipe.
3. Place the sensor at the bottom-most point in the channel. If excessive silt is present on the
bottom of the pipe, rotate the band in the pipe until the sensor is out of the silt. Refer to Figure 8.

Table 1 Selecting probe direction
Option Description
Upstream Recommended for most applications. The flow stream over the sensor should be as straight
as possible with no drops or turns near the measurement point.
Mount the sensor in the pipe with the beveled edge pointed toward the flow where the flow
stream enters the measurement area.
Downstream Use this option when the sensor is installed downstream of the measurement point (where
the flow stream exits the site). This option is useful when more than one flow stream enters a
site and the combined flow of all streams is measured at a single exit point. This option can
also be used if there are hydraulics preventing the sensor from being mounted in upstream
area.
Mount the sensor facing the flow.
Downstream
(reversed sensor)
Use this option when Option B will not work due to poor flow uniformity in the vault. The
maximum velocity read in this kind of installation is 5 fps when the AV9000 interface module
is not used. Mount the sensor in the downstream direction. The manufacturer recommends
verifying the velocity by profiling flow and using a velocity site multiplier, if required, for more
accurate reading.
Note: When the AV9000 interface module and submerged AV sensor are used with the FL900 logger, the
user has the option to select Reversed Sensor on the Sensor Port Set Up menu.

Excessive silt deposits have built up between the transducer and the protective cover
Notes
Do not touch the sensor transducer as this will cause damage and incorrect sensor operation.
Use only approved cleaning solutions as listed in Table 2. Do not use any type of brush or rag to
clean the pressure transducer as this will cause damage and incorrect sensor operation. If there
are debris, spray the membrane with water and use a Q-tip to carefully remove the buildup.
If the gasket is missing or damaged, install a new one. A damaged or missing gasket will cause
inaccurate readings.
After cleaning the sensor, clean the gasket and protective cover before they are installed.
After cleaning an oil-filled sensor, replenish the sensor oil.
If a sensor must be taken out of service for an extended period, do not store the sensor on a dry
shelf. The manufacturer recommends that the sensor be stored with the sensor head in a bucket
of water to keep the oil debris from crusting in the pressure transducer canal.
To clean the sensor:
1. Soak the sensor in soapy water.
2. Remove the screws from the protective cover. Refer to Figure 10.
3. Remove the cover and gasket. Refer to Figure 10.

N O T I C E
Do not operate the sensor without desiccant beads or with green desiccant beads. Permanent damage to the
sensor can occur.
Immediately replace the desiccant when it changes to green. Refer to Figure 11.
Note: It is not necessary to remove the desiccant container from the desiccant hub to install new desiccant.
At step 5 of Figure 11, make sure that the O-ring is clean and has no dirt or debris. Examine the O-
ring for cracking, pits or sign of damage. Replace the O-ring if it has damage. Apply grease to dry or
new O-rings to make installation easier, to get a better seal and to increase the life of the O-ring.
For the best performance, make sure to install the desiccant container vertically with the end cap
pointed down. Refer to Attach the desiccant hub on page 8.
Note: When the beads just begin to turn green, it may be possible to rejuvenate them by heating. Remove the
beads from the canister and heat them at 100-180 ºC (212-350 ºF) until they turn orange. Do not heat the canister.
If the beads do not turn orange, they must be replaced with new desiccant.
