ULTRASONIC LEVEL TRANSMITTERExplosion-Proof, Mapping Software, 3˝ (76.2 mm) Measuring ColumnThe 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 to 20 mA output. FEATURES/BENEFITS• 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• Mapping software makes effective measuring surface only a 3˝ (76.2 mm) diameter column with no concerns of ladders, pipes, or other tank intrusions in the remaining sound cone• FM approved explosion-proof making it ideal for use in hazardous locations• Easy programming with 6 digit LCD display and simple menu structure• Output range is adjustable with choices of inputting tank dimensions or by filling and emptying the tank while calibrating and it automatically and scaling to levels it senses• Window cover allows easy viewing of display• Fail-safe output options and diagnostic capabilities APPLICATIONS• Water and wastewater• Pulp and paper processing • Chemical processing • Food and beverage 3 29/32[99.21]8 1/16[204.79]2X 1/2 NPT4 9/32[108.74]ø3 21/64[84.53]SPECIFICATIONSService: Compatible fluids.
