The Ultrasonic Point Level System 9600 Series is designed to detect the level of Ultrs-Pure Liquid Chemical in Bubblers and Ampoules in the Semiconductor industry in PVD, CVD and ALD processes. The probe fits in the ½" or ¾" VCR fill port of the ampoules. There are no moving parts to the probe that may introduce impurities. It is not dependent on the color, dielectric, density and viscosity of the chemical. The design allows for multiple sensing points. All wetted parts of the probe is 316SS, electropolish finish and leak tested. Each probe is custom made to user's specifications and requirements.

The electronics are remotely mounted from the probes to allow for higher temperature applications. There is no calibration or adjustments between sensors.
