The graphical displays on the Model 2511A provide at least three very
useful functions: (1) During start up, the customer is instructed, step
by step, through the programming parameters which make the analyzer
operable; (2) Profiles the entire liquid column of the tank, showing ALL
solids interfaces. This will continually update stored information as
sounding data is revised; (3) A trend of the interface level of
interest, covering up to the last 24 hours, will continually be
updated and available to the graphical display with the press of a
The microprocessor in both instruments is also used to provide a
flexible, convenient customer interface with simplified setup,
calibration, and troubleshooting procedures. The displays, setpoint
relays, and remote outputs are all under direct microprocessor control.
As a result, data is scaled easily to suit the specific needs of the
Separate back lit, digital and graphical displays provide the numerical
location of the desired solids interface, as well as a profile of the
entire clarifier in real time. This profile visually depicts each
interface in the clarifier and labels their individual levels. The
amount of ultrasonic energy required for the reading is also shown on
the graphical display; this informs the user of the relative signal
absorption present in the clarifier at the time of the reading.
The fiberglass NEMA 4X instrument enclosure can be mounted on a vertical
or horizontal handrail, or a wall. The ultrasonic sensor with 25
feet of cable mounts on either a fixed support or a swing out bracket.
Designed specifically for the Model 2511A
analyzer, this economical sensor uses a single crystal to both transmit
and receive. Constructed of the same material as the 25DN; it is used in
non-chemical applications where the maximum temperatures do not exceed
175O F (80O C). Its
physical size allows the sensor to be inserted into a pipe with an I.D.
of 3". It incorporates a 3/4” 316 Stainless Steel nipple for
customer supplied pipe mounting.
