Cosense SL-900 series Ultrasonic Multi Point Liquid Level switches provide a robust, compact and cost effective solution for the detection and measurement of fluids in vessels where bubbling, foaming and turbulence are present. Single or multiple points for precise fluid level detection are designed to exact customer requirements. SL-900 sensors with tube-in-tube construction are utilized in the Semiconductor Industry for the most accurate and reliable level detection of high purity chemicals being stored in Ampules, Bubbler Tanks, Reagent Vessels, Supply Tanks and more. These sensors are critical in chemical vapor deposition processes, such as ALD, CVD, PVD, which is critical to the Semiconductor Wafer fabrication process. SL-900 Liquid Level indicators help to determine the amount of extremely costly ultra-high purity chemicals such as DMAH, TAETO, DEAT, TEOS and metallic precursors, to help minimize waste and maximize system efficiency and profitability. There are no moving parts in Cosense liquid level instrumentation so that debris and contamination from mechanical wear and tear are non-existent. Also, utilization of SL-900 sensors help to eliminate the possibility of mechanical float switches becoming stuck. Tank level gauges are available with integral or remote electronics depending on customer requirements.  Custom features can be ordered including sensor extension lengths up to 4 points of fluid detection as well as type of mounting including Sanitary flange options. SL-900 sensor assemblies are manufactured with 316LSS and can be permanently installed into fluid handling equipment to help insure the safe and continuous operation of these systems with pressures up to 250 PSIG ( 1724 Kpa).
