Peace of mind performance

The Sentinel LCT4 is a new addition to the Panametrics line of ultrasonic flow meters. Designed specifically for high accuracy measurement of crude oil, other liquid refined hydrocarbon products, and other non-hydrocarbon liquids, it delivers extremely reliable and repeatable results and meets the strict performance requirements of OIML R117-1 and API MPMS Chapter 5.8.

The LCT4 refines the high-reliability characteristics of its predecessor, the Sentinel LCT, into an aesthetically designed, compact meter body with integral cables, no extended buffers and no junction boxes. It continues to retain all of the advantages of ultrasonic flow measurement, including:

• No drifting or required periodic calibration

• No pressure drop

• No restriction in the pipe

• No moving parts and no filters or strainers

Sentinel LCT4 Ultrasonic Liquid Custody Transfer Flow Meter

High Accuracy Ultrasonic Flow Meter

A true multi-viscosity meter

The LCT4 uses a number of proprietary algorithms to reduce viscosity effects, making it viscosity independent. No prover run or change of settings is required when viscosity changes. The meter retains its accuracy over the whole range between minimum and maximum viscosity, using only one calibration curve.
