The Optisound VU3X Series Continuous Ultrasonic Level transmitter (photo) provides a reliable, repeatable and highly accurate (0.15%) continuous level measurement of liquids. It is capable of liquid level measurement to ranges up to 30 ft. with a 2-wire 4 – 20 mA, HART output signal. The Optisound VU30 sensor is constructed of CPVC for use in environments that are classified hazardous (Class I, Div. 1) with Intrinsically Safe or Explosion Proof installation requirements, temperature range from –0°C to 70°C and process pressures up to 50 psig. The compact electronics comes standard with an integral display and keypad for local configuration, and precludes the need for hand-held communicators or PC software. Internal software features support over 80 standard flume and weir characterizations with totalization display in a resettable and a non-resettable format. — Krohne, Inc., Peabody, Mass.
