Sentinel meters offer peace of mind to pipeline operators
Custody Transfer - Level flow measurement
When you’re transferring ownership of high-value raw and refined assets like petroleum and crude oil, you need to know you’re getting highly accurate, custody transfer-level flow measurements that meet the strict requirements of regional authorities. Our Sentinel high-accuracy ultrasonic flow meters deliver those high accuracy measurements – even in the unstable conditions typical of pipelines – to reduce uncertainty and increase peace of mind.
Meet the Sentinel high-accuracy ultrasonic flowmeters. And see why they’re the last word in flowmeter technology.
Our Sentinel flow meters deliver custody transfer-level measurement, easy integration, rugged construction, and reliable performance – even in the unstable conditions of typical pipelines. When you spec a Sentinel flow meter, you can rest easy knowing you’re getting the high-accuracy measurements and insights you need to operate cost-effectively and free from false alarms.
Product Features
-
Sentinel LNG Custody Transfer Liquid Flow Meter
-
The Sentinel LNG ultrasonic custody transfer liquid flow meter extends cryogenic applications to -200 C. Like other Sentinel meters it is reliable, robust and cost effective. With no moving parts, a robust path configuration and bundled waveguide technology, the signals can enter the process while protecting the transducers from cryogenic temperatures.
-
Sentinel LCT8 Custody Transfer Liquid Flow Meter
-
The Sentinel LCT is uniquely designed to meet the strict requirements for custody transfer of hydrocarbons. Its robust path configuration provides trouble-free operation that will not drift, even when the liquid product changes in the line.
The Panametrics LCT8 is the latest addition to the high-accuracy product line of ultrasonic flow meters. It delivers custody transfer-level measurement, even in the unstable conditions typical of pipelines. Its 8 measurement paths give operators enhanced visibility into their pipelines to support informed decisions and minimize risk.
-
Sentinel LCT4 Custody Transfer Liquid Flow Meter
-
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 LCT Custody Transfer Liquid Flow Meter
-
Sentinel LCT demonstrates new levels of performance and accuracy, reacts to changes in flow rate with incredible speed and is based on proven technology. Sentinel LCT is designed specifically for the custody transfer measurement of crude oil and other liquid refined products.
Ultrasonic flowmeters use transit time to determine the liquid or gas flow in a pipeline. Measured transit time consists not only of the time the ultrasonic signal spends in a fluid, but also of a portion of “dead time,” being the time that the electrical signal is converted into an acoustical signal and the time the acoustic signal travels inside the transducer. To allow for the utmost accuracy, Sentinel LCT uses pulse echo to actively measure the dead time. By sending a pulse and measuring its reflection, the dead time is measured in real time rather than using a preset value.
Sentinel High-Accuracy Ultrasonic Flow Meters: The right technology for your application
Liquid Custody Transfer
Liquid Custody Transfer
Custody transfer requires the highest level of accuracy of any pipeline application. That’s why operators choose Sentinel flow meters. They deliver custody transfer-level performance, accurate and repeatable flow measurements, and a design that’s rugged and easy to integrate.
Allocation Measurement
Allocation Measurement
Sentinel meters use a multipath inline flow meter method that permits a wide range of measurement for liquid hydrocarbons, making them ideal for custody transfer as well as allocation measurement applications. Whether you’re supporting ownership allocation or allocation in a comingled flow, you can count on Sentinel meters to deliver the accuracy you need.
Pipeline Leak Detection
Pipeline Leak Detection
Keep people, the environment, and your company’s reputation safe from harm by monitoring pipeline leaks with Sentinel meters. Ultrasonic flow meters like our Sentinel LCT8 provide enhanced diagnostics that compensate for changes in flow, giving you better visibility into your system and better confidence to determine real from false alarms.
