The LVU1500 series has been discontinued. Please contact our Flow Engineering department for a possible substitute. The LVU1500-LP Series Two-Wire (“Four-Wire” for four wire unit), non-contact continuous level transmitter, is easy to program, can be used in hazardous locations, and offers unique stainless steel and 3/4 NPT sensors. It is a great choice for sanitary, hazardous, dirty, corrosive or high purity processes. The 4 to 20 mA output is compatible with all control systems and updates quickly making the LVU1500 Series the right choice for fast filling processes.

The LVU1500 Series is plug-andplay. Digital signal processing, and automatic temperature compensation eliminates all adjustment except zero and span. Zero and span calibration is set directly in inches using digital switches and requires no power. The rugged epoxy coated aluminum enclosure survives where plastic enclosures fail.

Operation The sensor is mounted on the top of the tank. The electronics generate an electronic signal that is converted by the sensor to ultrasonic pulses that are transmitted through air space.

At the liquid/air interface, the pulses are reflected back to the sensor. These echoes are received by the microprocessor in the electronics, which samples the echoes and calculates the level in the tank.

A continuous output of 4 to 20 mA (isolated) adjustable in increments of 1"/0.1" over entire span is provided to satisfy a number of applications. Programming is done through a pair of BCD switches.
