We provide standard and customized liquid level sensors (LLS) that measure discrete liquid levels by using ultrasonic technology. The configuration is decided by process requirements and ampoule type. With Exentec’s expertise, our level sensor can operate in high-temperature and high-density/viscosity environments to support process and material technology needs. 

Benefits

• Discrete level sensor probes up to 8 points
• 316L wetted surfaces are excellent for use in ultra-high purity (UHP) applications
• High liquid viscosity/density capability
• High temperature capability, models up to 200° C  
• TC and RTD integration capabilities

Features

• Wetted surfaces 316 L stainless
• Wetted surfaces electropolished to 10 Ra max
• High temperature capable models; up to 200° C
• Pressure rated up to 300 psi
• ±1.5 mm trigger points at each discrete level
• ±0.75 mm is typical repeatability of trigger points
