PopisThe LVU-950 series non-contract micromeasurement system uses very small sensor technology to fit into applications where ultrasonic, non-contract systems previously could not be used because the sensor was too large. The LVU-950 series consists of the transducer and state-of-the-art microprocessor-based electronics housed in a NEMA 7 explosion-proof enclosure. The LVU-950 is available standard with 3 /4 " MNPT mounting for ranges for 0.5 to 10 ft. distance, settable in 1" increments on the BCD switches; option “-HR” allows setting to the nearest 0.1" up to 99.9" from the sensor. Option “-20FT” allows measurements from 1 to 20' distance, settable in 1" increments. The “20FT” option has a 2" MNPT mounting. The sensor is mounted on the top of the tank. The electronics generates 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 electronics, which samples the returned echoes and calculates the level in the tank. A loop powered 4 - 20 mA output, updated every second, is provided. Programming is done through BCD switches.
