# Product Introduction
The LCT8 adopts the groundbreaking Sentinel LCT4 design and can be seamlessly integrated into pipelines or processes. When a smaller installation footprint or pressure drop is a consideration, the eight-path design allows for shorter upstream and downstream lengths. Compared with other flow meters, the LCT8 fully embodies the advantages of ultrasonic flow measurement, including:
- No drift and no need for regular calibration
- No pressure drop
- No pipeline restrictions
- No moving parts, no filters or strainers
## True Multi-Viscosity Meter
The LCT8 utilizes a range of proprietary algorithms to mitigate viscosity effects, rendering it immune to viscosity variations. No proving runs or setting adjustments are required when viscosity changes. The meter maintains its accuracy across the entire minimum and maximum viscosity range with only a single calibration curve.
