What our customers have to say…
“The meters have been working great!
We picked the sites they should be in
and they work perfect there.”
Sewer System Maintenance and Operations Department (SSMO)
NEORSD (Northeast Ohio Regional Sewer District)
“Data Delivery Services is extremely helpful
and has significantly increased our efficiency.”
AH Environmental
“It did not make sense to invest a large sum of
money into capital expenditures that were only
needed for two years. With a fixed price per meter,
per month, DDS was perfect for us.”
City of Carmel, Indiana
“The fact that you don’t have to touch anything
in the sewer is ‘perfect.’ I have been doing this
for 18 years so I’ve seen it all. It is easily understood
why anyone working in the sewer environment
would prefer the ‘hands-off’ approach and
freedom from entering monitoring sites that the
Flo-Dar meter affords. These meters are nice.
I also like the battery system.”

Sigma Model 920 Area Velocity Flow Meter
Rugged housing is NEMA 6P sealed to withstand
submergence and prolonged surcharge
conditions. A low power draw creates
an extended 90-day battery life.
Made for Submergence and Prolonged
Surcharge Conditions
The rugged housing of the 920 Flow Meter is NEMA 6P sealed to
withstand submergence and prolonged surcharge conditions.
A low power draw creates an extended 90-day battery life.
Versatile Features and Options
The optional rainfall logging feature records and characterizes rain
events—a true innovation in water monitoring. Use the optional
internal modem to automate data retrieval, paging, and reporting.
With multiple sensor options, this meter can be used for redundancy,
averaging, and multiple pipe monitoring.
Advanced Technology for Accuracy
• Automatically corrects for temperature effects
• Uses patented “drawdown correction” to correct the effects
of velocity on accurate depth measurement
• Advanced Doppler technology avoids signal dropouts and ensures
accuracy in low-flow, full-pipe, or reversed-flow conditions
• The only true In-Pipe ultrasonic sensor with zero dead band.
Use our In-pipe sensor in combination with a Low Profile Area
velocity sensor to monitor flow in pipes or channels with depths
less than 2 in. Also combine an Ultrasonic In-Pipe sensor with a
regular Submerged Area Velocity sensor for depth measurement
redundancy to avoid depth data gaps.
Easy Installation and Maintenance
Installs quickly and easily with no velocity calibration required.
Note: Hach Data Management software is required to program this Flow Meter.

Intrinsically Safe AV Flow Meters
Sigma Model 940 Intrinsically Safe Area Velocity Flow Meter
Its rugged design, low-profile probes, and one-year battery life significantly reduce site visits.
Choose up to two area velocity sensors, or one area velocity and one depth backup. Whether
you require redundancy in a single pipe or depth and velocity in separate pipes, you’ll profit
from new performance levels in a single meter.
Industry standard MODBUS ASCII protocol has been incorporated into the American Sigma
940 Flow Meter. The implementation of the MODBUS protocol allows your SCADA or DCS
system to directly communicate with the 940 Flow Meter without the use (or additional cost)
of a PLC.

Sigma Model 950 Series Area Velocity Flow Meter
Offers maximum flexibility for multiple applications.
The Sigma Model 950 Series Permanent/Portable
Open Channel Flow Meters provide portable
and/or permanent single-channel monitoring
plus water quality testing, process control
interface, and digital display.
(Sensors sold separately.)
Versatility and Customization
The Sigma 950 series are the meters of choice by flow professionals, consultants, and
municipalities. Choose from any of the following technologies to fit your application.
• Use the Submerged Area/Velocity flow meter to measure flow in collections systems
for periods up to 40 days using our 6 amp-hr gel electrolyte battery
• Use any of our depth technologies when primary devices (Weirs and Flumes) are available
to measure depth and calculate flow
• The bubbler depth technology is ideal for applications with high winds, high temperature
or when foam is present
• The combination of bubbler depth technology and doppler velocity is the favorite of
storm water professionals
• The ultrasonic depth technology is ideal to monitor industrial dischargers for your
pre-treatment program in combination of any of our Automatic Wastewater samplers
Sampler Pacing and Equipment Control
The 950 Flow Meter is the perfect choice to do flow pacing sampling with portable samplers.
Control samplers, pumps, or other equipment based on monitored flow or selected
parameter(s). Sampler pacing provides the ability to document overflow problems.
Note: Hach Data Management software is required to program this Flow Meter.

Sigma RAIN LOGGER™
Automatic Data Logging Rain Gauges
Built to National Weather Service standards, the Rain Gauge accurately measures rainfall in
0.01" increments. The rain gauge can be connected to a Hach Sigma Model Flow Meter, or
the Rain Logger can be used for stand-alone or long-term rainfall recording, as well as for
portable use in stormwater runoff monitoring.
Key Features
• Stainless steel funnel screen prevents plugging from leaves and other
wind blown debris
• Removable funnel makes cleaning easy
• Built-in bubble level, with an innovative springloaded base plate provides an easy,
convenient means to level the gauge
• Base plate permits secure anchored installation
• Compatible with Sigma Flo-Center and Insight Data Management
and Analysis Software
