INTRODUCTION Contents Page Start Small Size Engineered Plastic LS-300 Series ....................................................... B-3 Accurate and reliable sensing method Ideal technology for difficult fluids Gems delivers the answer for challenging fluid measurement with our new ultrasonic UCL-510 Transmitter/Multipoint Level Switching Combo. This accurate and reliable sensor is designed for the most difficult fluids to monitor - including ultrapure, dirty, coating, scalding or corrosive types. Typical Media * Acids * Wastewater * Inks and Paints * Slurries * Food and Beverage * Semiconductor Process Chemicals * Oils and Petroleum Distillates How Ultrasonic Monitoring Works Mounted at the top of a tank, the sensor continuously transmits pulses of high-frequency sound waves that travel away from the sensor, hit the surface of the liquid and return to the sensor. Solid-state electronics measure the time it takes from transmitted sound to return of the echo. With reference to the speed of sound in air, the exact distance of the liquid surface from the sensor can be calculated with high accuracy (±0.125˝ (3mm) of maximum range). Level/Distance measurements are automatically temperature-compensated throughout the operating temperature range of the sensor. LS-300TFE Series ..............................................
