METER OVERVIEW

General

The DXN portable ultrasonic flow meter is designed to measure volumetric flow rate within a closed conduit . The transducers

are a non-contacting, clamp-on or clamp-around type, which provide the benefits of non-fouling operation and ease

of installation .
In

Transit Time

mode, the flow meter uses two transducers that function as both ultrasonic transmitters and receivers . The

transducers are clamped on the outside of a closed pipe at a specific distance from each other . The transducers can be

mounted in V-Mount, where the sound transverses the pipe two times, W-Mount, where the sound transverses the pipe four

times, or in Z-Mount, where the transducers are mounted on opposite sides of the pipe and the sound crosses the pipe once .

The selection of mounting method is based on pipe and liquid characteristics, which both have an effect on how much signal

is generated . The flow meter operates by alternately transmitting and receiving a frequency modulated burst of sound energy

between the two transducers and measuring the time interval that it takes for sound to travel between the two transducers .

The difference in the time interval measured is directly related to the velocity of the liquid in the pipe .
Internally, volumetric flow rate is derived from fluid velocity and the cross-sectional area of the pipe inner diameter .

Tpplication Versatility

The flow meter can be successfully applied on a wide range of metering applications because the meter has both transit time

and Doppler capabilities . A full range of fluids—from ultrapure to thick slurries—can be measured .
The flow meter can be used on pipe sizes ranging from 0 .5…120" (12…3048 mm) while accommodating a wide variety of

liquid applications:

ultrapure liquids

cooling water

potable water

river water

chemicals

plant effluent

sewage

sludge

Temperature Ratings for Transducers

Because the transducers are non-contacting and have no moving parts, the flow meter is not affected by system pressure,

fouling or wear . Temperature ratings for each transducer are listed below .

Transducer

Temperature Rating

DTTR

–40…250° F (–40…121° C)

DTTN

–40…185° F (–40…85° C)

DTTL

–40…194° F (–40…90° C)

DTTSU

–40…194° F (–40…90° C)

DT94

–40…194° F (–40…90° C)

DTTH

–40…350° F (–40…176° C)

OTEE:

N

When the type of transducer is selected, the flow meter automatically chooses the correct transmission frequency for

that transducer set .

Data Integrity

Non-volatile flash memory retains all user-entered configuration values in memory for several years at 77° F (25° C), even if

power is lost or turned off .

Product Identification

The serial number and complete model number of the flow meter are located on the

bottom surface of the flow meter’s body . If you require technical assistance, please

provide the customer service department with this information .
