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.

CARTRIDGE: 304 Stainless Steel.
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.

ENCLOSURE MOUNTING
Hinge Lock and Optional Key Lock
Two plastic gray plugs are supplied with the Accuron
meter housing. The plugs may be utilized to
permanently lock either side of the cover by inserting
them into the keyhole. The optional Keylock may than
be used to lock and unlock the other side of the cover.
The key can only be removed if the cover is in the locked
mode.
Do not face the display towards the sun. A sunshade
must be used for outdoor installation. Conduit
openings must be properly prepared and sealed to
maintain the NEMA 4X rating.
The enclosure is rated IP
66 (NEMA 4X) and can be mounted indoors or out. There
are two stainless steel mounting brackets attached to the
enclosure.
The mounting tabs have slots for 1/4” bolts (4 places). The
electronics should be mounted with the display at eye
level or lower. There are five 1/2” holes in the bottom of
the enclosure for conduit fittings. These holes have rubber
plugs installed at the factory.
Opening the Enclosure:
There are two hinged floor clasps on the front cover of the
enclosure. To open, place thumb on one of the hinges, pull
toward the outside of the enclosure. Once the hinge pops
to the outside it will retract allowing the clasp at the
bottom of the hinge to release. Swing the cover towards
the front to open. The opposite side will act as a hinge to
swing the door freely. To close, re-attach the hinge into the
clasp and push the top of the hinge toward the enclosure
until it locks.

IMPORTANT
Before pulling the sensor cables through the conduits,
mark the ends of the cables to indicate which is the
upstream and downstream sensor cable. Leave
approximately 1 foot of cable extending from the
conduit in the enclosure. Prepare the cable ends in the
following manner.
NOTE: All Drawings are to scale.They may be used as a
template.
1. Remove outer cable cover.
Measure 1-7/8” from the end of
the cable. With a cutting tool,
carefully cut through the outer

PROPER INSTALLATION CONFIRMATION
Sensor cable connection continuity test.
This test will require the use of an ohmmeter. With the
power off, connect the test leads of the ohmmeter to
Points 1 and 3 of the sensor cable connections on the
sensor terminal block. The ohmmeter should read 10,000
ohms +/- 5%. Repeat this test at Points 2 and 3.
Connect the test leads to Points 3 and 4.
The reading should indicate infinity (or an open).
Connect the test leads to Points 1 and 4, then 2 and 4.
