NON-CONTACT ULTRASOUND
344/345
For Liquid Level,
Volume or Open
Channel Flow
A remote mounted, full-featured ultrasonic transmitter with
extensive agency approvals. Many transducer configurations
and transmitter options are available for greater versatility.
L
Convenient Front Panel Interface
Front panel keypad makes programming convenient;
once wired, there’s no need to open the enclosure.
A large, 16-character alphanumeric display shows all
parameters and a password code prevents unautho-
rized tampering with configuration data.
L
Choice of Transducers
The Model 344 employs the powerful 38 kHz Kynar transducer
used primarily for level and volume applications. The Model 345
uses the 50 kHz transducer, available either in Kynar or 316
stainless steel. Transducers feature temperature compensation.
