Series ULT Ultrasonic Level Transmitter provides reliable, accurate,
noncontact measurement of liquid levels. Ultrasonic non-contact technology
offers no moving parts to wear, jam, corrode, or get coated like contact
technologies. Mapping software makes effective measuring surface only a 3˝
diameter column. No concerns with ladders, pipes, or other tank intrusions in
the remaining sound cone. Unit is FM approved explosion-proof making it ideal
for use in hazardous locations. The ULT features easy programming with 6 digit
LCD display and simple menu structure. Output range is adjustable with
choices of inputting tank dimensions or just fill and empty the tank while
calibrating and it automatically scales to levels it senses. Window cover allows
early viewing of display. Failsafe output options and diagnostic capabilities
makes the ULT a good choice for critical applications.
