  Ultrasonic Benefits

  • Low Pressure Drop - The same as an equal length of straight pipe
  • Low Maintenance - No moving parts that need replacement due to wear, providing stable measurement over the life of the meter
  • Diagnostic Capabilities - Real time, on-line performance verification   
  • High accuracy – Custody transfer accuracy over wide range of product types and viscosities
  Ultrasonic Features
  • Software Capabilities - Integrated meter software provides real-time logs, trends, signal performance and parameter reports for operation, diagnostics and maintenance
  • Web based Interface – Easy-to-use interface accessible through a standard web browser for ease of access  
  • Integrated or Remote Color Touch Screen Display - The optional color touch screen display can be attached as the front panel of the meter electronics or remotely mounted using the optional wall mount enclosure suitable for hazardous areas
  • Optimized transducer design - Specialized transducers are available to extend meter size and viscosity capabilities
  • In-line Transducer Replacement - Designed so there is no need for special tooling or process shutdown to replace a transducer
  • Reciprocity - Transducer and electronic design that virtually eliminates zero flow offset and drift to provide long-term measurement stability independent of pressure, temperature and transducer aging

Online Diagnostics and Support

Remote Support from Factory Experts:

  • Web based meter software does not require special interface software improving access to meter diagnostic features and fluid property calculations
  • Service technicians can access a meter from any computer with a secure network connection allowing quicker and more flexible access to diagnostic information
  • Simple intuitive screen designs encourage usage of advanced features and diagnostic capabilities
  • Download historical log files from the meter's on board memory to compare conditions before, during, and after process upsets or line integrity alarms for an in depth follow up.

The Smith Meter Ultra Series diagnostic capabilities provide the operator with the real time tools to monitor the meter's health, performance, and operating conditions ensuring the most accurate measurement over time. The visual interface to the meter electronics is accessed through any simple web browser and the meter's unique IP address through a secure network. Because of the unique web based interface, no additional software is needed to maintain on you PC or hand held device on the network for remote access.

In addition, the on board memory will revolutionize the use of historical data in diagnostic analysis. While other meters require PC memory to log meter performance data, the Ultra Series meter stores the meter data on board in real time. Any meter alarms can be investigated against detailed historical log data for a root cause analysis.  This is because you can download the meter performance history before, during, and after an alarm condition. This provides the critical data and insight for fast troubleshooting and decision making in service.

Fluid Properties

  • Viscosity, Density and Reynolds Number - Properties are estimated using algorithms with temperature and pressure inputs

Flow Profile Parameters

  • Profile Flatness - Axial flow velocity of outer paths compared to the center paths compared to the center paths. Reynolds number dependent. Deviation at similar conditions < 2.0%
  • Profile Symmetry - Velocity of top paths compared to the bottom paths. Reynolds number dependent. Deviation at similar conditions < 2.0%
  • Swirl Flow - Amount of transversal flow that is rotating in the pipe. Reynolds number dependent. Deviation at similar conditions < 2.0%
  • Cross Flow - Amount of transversal flow that has two rotating vortexes. Reynolds number independent. Deviations at similar conditions < 2.0%
  • Turbulence - Describes the stability of the flow measurements on each path. Flow velocity dependent. Deviation at similar conditions < 1.0%

Note: Swirl and Cross Flow are only available with the Ultra 6c and 8c meter.

Signal Parameters

  • Velocity of Sound (VOS) - Measured on each path to ensure correct measurement of ultrasonic pulses. Density dependent. Deviation <1.5m/s
  • Signal to Noise Ratio (S/N) - Measures the signal strength and noise. Should be >20dB. Used drop in performance on similar conditions should be examined.
  • Signal % - Designates the signal quality. Should be >50%. Drop in performance on similar conditions should be examined.
  • Gain - Indicates signal strength. Influenced by density, viscosity, and impurities. Deviation <6
