ACCURON CARTRIDGE METER SERIES 7200
GENERAL DESCRIPTION LOW FLOW MONITORING
Accuracy ±3-5% (act.rate)
Turndown: 60:1 During periods
of minimal flow (Zero to 1/3
pipe diameter), the Accuron
measures flow within it’s low
operating range by utilizing the
highly efficient combination of
a trapezoidal flume and
ultrasonic level sensor.
HIGH FLOW MONITORING
Accuracy ±1-2% (act.rate)
Turndown: 60:1 During periods
of maximum flow (1/3 to full
pipe diameter). The Accuron
measures flow within its high
operating range by utilizing an
extremely accurate area-velocity
system that combines an
ultrasonic level sensor with a
pair of transit-time velocity
sensors.
The Series 7200 Cartridge Meter is designed to measure
flow in open channels or partially filled conduits. The
Cartridge Meter utilizes ultrasonic measurments
techniques to determine fluid velocity and fluid depth
for calculating volume of flow.
The Series 7200 Cartridge Meters are calibrated at the
factory to the application parameters provided by the
customer. On-site calibration of the system is usually
never required.
By combining proven flume/level sensor technology with
chordal transit-time velocity measurements, the Accuron
7200 (pat.pend.) ushers in a new age of highly efficient
open channel flowmeters consistently operating in a 1-
5% (actual rate) accuracy range.
Eastech combines two highly accurate and proven
technologies within a single-dual range unit. Low flows
are consistently measured by an extremely reliable
stainless steel trapezoidal flume/Teflon® level sensor
combination. Higher flows are accurately ascertained by
combining the same Teflon level sensor with a pair of
non-fouling transit-time velocity sensors. Transit-time
chordal measurement is the most viable technique for
predicting average velocity. It provides for detection of
chordal velocity across the entire path of the fluid being
measured.

ULTRASONIC LEVEL SENSOR:
The risk and expense
associated with repetitive confined space entry due to
fouled submerged sensor problems is eliminated by
utilizing an “above the flowstream” submersible Teflon
level sensor.
TRAPEZOIDAL FLUME:
The flat straight through bottom
permits the flume to pass debris quite readily and
reduces the problem of sediment build-up upstream of
the flume.
TRANSIT-TIME VELOCITY SENSORS:
Designed to
prevent the accumulation of rags, branches and similar
debris from interfering with the performance of the
transducers.

STEP 3
Use a pencil or marker and mark the four
slotted holes provided in the flange of the
Cartridge. Remove the cartridge from the pipe.
NOTE: If the sewer pipe is not flush with the
sewer wall, utilize the two turnbuckles
provided. Insert the hook end into the hole
below the handle of the Cartridge and attach
other end to the sewer wall with the lag bolt.
Rotate the Cartridge until the bubble in level
provided is centered.
