Intrusive Ultrasonic Meter
Ultrasonic Meter Ultra 4c
Manufacturing: Guidant Measurement, Smith Meter® brand
The Ultra 4c Ultrasonic Liquid Meter is a four-transducer-pair meter designed for Fiscal and Custody Transfer measurement of low- to medium-viscosity crude oil and refined products. Featuring advanced multi-path measurement technology, the Ultra 4c accurately resolves complex flow profiles while maintaining exceptional linearity and repeatability across a wide range of operating conditions. Ideal for compact installations, the equipment exceeds the most demanding industry specifications.
How it works
The Ultra 4c calculates flow by measuring the transit time of ultrasonic sound signals traveling back and forth through the moving fluid. Signal transmission and detection are performed by piezoelectric transducers located on both sides of the measurement path. Flow velocity is calculated from the transit times, and these velocities are integrated to determine the total volumetric flow rate through the meter. The transducers are non-intrusive and mounted flush, ensuring low maintenance requirements and no obstructions to the full flow passage through the pipeline.

Ultrasonic Meter Ultra 8c
Manufacturing: Guidant Measurement, Smith Meter® brand
The Ultra 8c Ultrasonic Liquid Meter is a meter with four pairs of transducers, designed for Fiscal and Custody Transfer measurement of low to high viscosity crude oil and refined products, operating under low Reynolds number conditions (with dynamic profile compensation that allows extremely linear performance, from laminar to turbulent flow systems).
Its advanced multi-path measurement technology accurately resolves complex flow profiles while maintaining exceptional linearity and repeatability across a wide range of operating conditions. Ideal for compact installations, the equipment exceeds the most demanding industry specifications.
How it works
The Ultra 8c calculates flow by measuring the transit time of ultrasonic sound signals traveling back and forth through the moving fluid. Signal transmission and detection are performed by piezoelectric transducers located on both sides of the measurement path. Flow velocity is calculated from the transit times, and these velocities are integrated to determine the total volumetric flow rate through the meter. The transducers are non-intrusive and mounted flush, ensuring low maintenance requirements and no obstructions to the full flow path through the pipeline.
