TRANSIT-TIME FLOWMETER
WITH DATALOGGER
The 5022 is a highly advanced microprocessorbased ultrasonic flow transmitter for extremely
accurate measurement of flow in open channels.
Since a 10% error in level measurement can result
in a 25% error in flow measurement, the high
accuracy (0.02”) of the Model 5022, especially
when utilized for billing purposes, directly
translates into dollars.
The Model 5044 transit-time flowmeter offers plant
operating personnel a highly reliable instrument
(±0.5% of actual rate of flow) that is nonintrusive in
design. Simple to install, with a one-piece SpeedrailTM
sensor mounting system and factory pre-programmed
for ease of start-up, the 5044 Chartmeter will consistently maintain accurate readings over changing
process conditions and time.

PARSHALL FLUMES
Parshall Flumes
Description
The Parshall flume is one of a large class of
open channel primary elements known as
critical flow venturi flumes. A distinguishing
characteristic of the Parshall flume is the downward sloping invert of the throat. This feature
gives the Parshall flume its ability to operate at
higher ratios of downstream to upstream head
than any other such device.
The Parshall flume manufactured by Eastech
Badger is a monolithic fiberglass reinforced
polyester structure to assure maximum strength
and accuracy of dimension while minimizing
installation time. A staff gauge with 1/4” minor
divisions in inches is standard. A 2” NPT stilling
well connection is available as an option.
Application
The Parshall is recommended for those applications in which moderate concentrations of
sand, grit or other heavy solids exist and fluid
velocities entering the flume are subcritical.
The flume operates with a small energy loss or
change in channel grade, about one-fourth
that of weirs having the same crest length.
The flume is ideally suited for fluid measurement in irrigation channels or sewers.
Features
Sturdy Reinforced Fiberglass Construction#
Sizes from 3”up to 36”#
Stilling Well Connection Available#
Calibration
The Parshall flume exhibits reproducible head
rise/flow rate characteristics throughout its size
range. In order to assure the accuracy of the
device, adherence to all dimensions for construction as well as free flow hydraulic conditions is required.

PARSHALL FLUMES
Sample Specifications
An Eastech Badger Model _______ Parshall flume shall be installed
as shown on the plans in accordance with the manufacturer's
recommendations. The Parshall flume shall be of single-piece
reinforced polyester construction with end flanges and reinforcing
ribs providing secure and permanent anchorage.
Sizing
Selection of a Parshall flume should be made on expected flow rates;
but for single point measurement to be valid, the design hydraulic
gradient must insure that free flow conditions exist at all flow rates.
Thus, the downstream fluid level must not exceed the values in Fig. 3
or single point measurement will not produce acceptable values.
The flume should be located in a straight reach of channel without
bends or changes in alignment directly upstream and should have a
well-distributed velocity profile. To assure free flow energy conditions exist, maintain the minimum and maximum flow rates as indicated for each flume size in capacity curve diagram. (Fig. 2)
Theoretical Discussion
The Parshall flume is an empirically derived and rated measuring
device. The discharge capacities are rated for “free flow” conditions in
which the submergence (ratio of downstream depth, to upstream
depth Hb/Ha) is less than the percentage given in Fig. 3. As the
downstream depth increases, flow condition is no longer critical, thus
two depth measurement readings (at Ha and Hb) are necessary and
a correction factor must be applied to obtain the correct discharge
under these conditions. The following graph presents these corrections necessary to ensure true discharge values.
