KROHNE”s OPTISOUND VU3X Series continuous ultrasonic level transmitter is designed for level or open-channel flow measurement in industrial and municipal applications. The transmitter provides reliable, repeatable and accurate (0.15 percent) continuous level measurement of liquids. It is capable of liquid level measurement to ranges up to 30 ft. (9.1 m), with a two-wire 4-20mA, 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 -40 F to 158 F (-40 C to 70 C) and process pressures up to 50 PSIG. The system is available with either a two-inch NPT or two-inch BSP process connection. The electronics comes standard with an integral display and keypad for local configuration. Internal software features support over 80 standard flume and weir characterizations with totalization display in a resettable and a non-resettable format. Custom characterizations for non-standard flow or tank shapes can be set up through a 21-point strapping table. The OPTISOUND VU3X series features patented algorithms that allow the system to ignore most internal vessel obstructions that may be positioned directly in the ultrasonic beam path without the need for user intervention. The sensor also can be recessed in vessel nozzles to allow measurement to the very top of the vessel.
