The new Model 3000 is a hand held computer and data logger designed specifically for the measurement of open channel
velocities and the on-site computation of stream discharges (flow). Features Include:
Model 3000 Indicator
The Model 3000 Indicator is a datalogging version of the Model 2100, allowing the operator to input all measurement data usually kept on a clipboard
while crossing a stream. The Model
3000 records depths, widths, velocities
and angles along with time & date of
measurements. It figures the “Q” and
can upload all this information in spreadsheet-acceptable format to your PC for
further study and record keeping. It
updates and is fully compatible with all
previous Swoffer instruments.
Model 3000 with optional sensors
❒ Efficient Photo-Fiber-Optic sensor coupled with precision quartz crystal controlled electronics
provide accurate repeatable data in most flow conditions.
❒ The Model 3000 Indicator displays data in feet and meters per second. Toggle the 0 key at the
main screen to change from one to the other.
❒ Velocity averaging is fully user adjustable. Anything from 1 to 999 seconds of averaging can be
chosen. The Model 3000 automatically powers up using your last averaging time period. If you
use 40 seconds, it stays at 40 seconds until you change it.
❒ Velocities can be a single averaged measurement or can be the accumulated average of as many
measurements as desired, all controlled from the keypad.
❒ Sensor components (propeller, rotor, and rotor shaft) are easily and inexpensively replaceable.
Carry spares into remote locations and you’ll never have to return early because of a bent
propeller or bucketwheel, or a lost propeller magnet or rotor shaft.
❒ Wide choice of sensor carriers or “wands” to accommodate virtually any open stream velocity
measuring requirement.
❒ Indicator keys are color coded, grouping related functions into like colors.
❒ Lightweight, portable system is easy to work with all day in the field. Model 3000 Indicator
uses the same rugged, weatherproof instrument housing as the earlier Model 2100 and Model
2200 but with added water incursion protection and data storage features.
❒ A simple and accurate method of user-accomplished calibration is provided with the Model
3000. No other current meter provides the user a method of checking and changing
calibrations in the field.
❒ Calibration settings for 10 different sensors/propellers can be stored in the indicator and the
Model 3000 is completely compatible with all earlier Swoffer Instruments’ sensors (Models
1000, 2000, 2100 and 2200).
❒ The Model 3000 is also specifically designed to function also with Price type AA & Pygmy
current meters using either the optical adapters pioneered by Swoffer Instruments in the Models
2200 and USGS-HIF Optic-Head sensors or with meters using the newer magnetic head
contactors. The Model 3000 can in fact be field calibrated to operate with any sensor that uses a
contact closure signal system.
❒ Prompts on the Model 3000 liquid crystal display assist the user through all operations; from
simple velocity measurements to discharge flow computations.
❒ On-board clock time-stamps data collected while in the Discharge Mode. (Month, day, year, hour
& minutes). Data units (feet or meters) is also saved and uploaded with file transfers.
❒ In the Discharge Mode as many as 1000 “stations” in from 1 to 100 stream cross-sections can be
acquired and stored in memory. Station No. (width) and station depth are entered directly by the
keypad and velocity and flow is computed by the Model 3000.
❒ If stations have velocities at an angle other than perpendicular to the stream cross-section
the angle can be input by keypad. The Model 3000 then applies a cosine correction for that
Station; necessary for using the Model 3000 with vertical axis current meters only.
❒ The accumulated discharge for a transect can be computed and displayed at any time during
or after a transect. Individual Stations in a transect can be added or deleted as desired and
each component of a station (Station No., Depth, Velocity and Angle) can also be edited.
❒ All discharge data in the Model 3000 can be transferred to a Personal Computer via USB for
further processing. Simple file transfer software and a USB connection cable is provided.

MODEL 3000 FLOWMETER - DATALOGGER
The Model 3000 Indicator is a datalogging version of the time proven Model 2100. The 3000 allows the operator to input and store measurement data usually hand written to a clipboard while profiling streams for discharge measurement. The Model 3000 can record depths,
widths, velocities and angles along with time & date of measurements. It holds 1000 “Stations” in any combination of 1 to 100 “Transects”
or “Sections”. It can figure the “Q” (total discharge) and upload all the information in spreadsheetacceptable format to your PC for further study and record keeping.
You can set the sampling (or averaging) time anywhere from 1 to 999 seconds and true averages can be
attained by adding any single reading to multiple successive readings.
The 3000 Indicator is fully compatible with all previous sensors so it can also be purchased separately to
update earlier Swoffer instruments. It can also be used with the USGS “Price Type” AA & Pygmy current
meters, with or without the Swoffer-designed Model 2200 optical retrofit.
Calibration ratings for up to 5 different sensors (PROPS on the indicator keypad) are stored in the Model
3000 plus calibrations for AA and Pygmy meters using either the Swoffer Model 2200 optical retrofits or the
magnetic head contacts. An easy self-calibration feature enables you to check operation of the instrument while in the field and all calibration data may be edited if needed. The Indicator powers the sensor
only when it is required for a measurement so batteries last longer. The onboard clock can be set anytime
and remains in operation even after shutdown. And, if you forget to turn the Model 3000 off, it doesn’t.
After 20 minutes of inactivity it automatically shuts itself off. Powered by four AA batteries, the Model
3000 instruments are very light weight and easy to use even all day in the field.

THE SWOFFER OPTICAL-ELECTRONIC SENSOR
The basic principle of the Swoffer sensor is simple; multiple bundles of fiber-optics, assembled into a propeller-driven rotor, gate a beam of infrared
light from a photo diode to a photo-sensitive transistor. The rate of rotation of the propeller rotor is directly proportional to water speed, therefore,
pulses produced by the photo transistor over a given time are also directly proportional to water velocity.
The Model 3000 uses a propeller rotor which requires very little energy to activate, works in nearly all water conditions and produces
consistent, strong output pulses even at low speeds. The calibration curve for the rotors is linear and consistent in all normally occurring
open channel velocities. The propellers used with the Model 3000 were specifically designed for use in water so they do not need a shroud
to protect them from the effects of turbulence. Because no shroud is used the propellers are better able to shed debris normally found in
sewers and natural streams.
The electronic half of the sensor consists of the latest opto-electronics and is epoxy encapsulated in a ½” (12.7mm) diameter acetal resin
housing for protection from chemicals and the elements. The sensor uses a two-wire signal system requiring as little as 3 volts for operation
and can generate an output signal through over 1000 feet of cable. The sensor consumes very little power, produces four pulses per
revolution and can be manufactured in a variety of configurations and, most of all, it is sturdy and reliable.
The standard version of the propeller rotor assembly (2100-A21) uses a very low friction fiberoptic rotor, a polished and hardened stainless
steel shaft, and a glass-filled nylon propeller. All rotor parts are easily replaceable in the field and spares are provided with every Model
3000 instrument.
