The Series ULT Ultrasonic Level Transmitter provides non-contact measurement of
liquid levels in an explosion-proof body. It is capable of measuring up to 32.8´ (10 m)
with a PVDF sensor and 4-20 mA output.

BENEFITS/FEATURES

• Provides reliable, accurate, and non-contact level measurement of compatible
liquids

• Non-contact technology offers no moving parts to wear, jam, corrode, or get coated
like contact technologies
