Q.Sonic Ultrasonic Gas Flow Meters Instromet

1 Ultrasonic Gas Flow Meters Instromet Ultrasonic Gas Flow Meters 02 Elster Instromet Elster Instromet Ultrasonic Gas Flow Meters Deliver Unparalleled Performance Elster Instromet 's series is the most accurate and flexible Ultrasonic meter for custody transfer applications. Advantages Large turn down ratio Theory of Operation An Ultrasonic flow meter takes advantage Bi-directional of the principle that an Ultrasonic pulse Flow profile detection travels faster with the gas flow than against the flow.

2 The larger the difference CMB signal processing between the upstream travel time versus Swirl and asymmetry detection the downstream, the more gas has passed through the meter. The advent Reflective technology of high speed computer processors has TwinSonic, a with made it possible to detect very small time redundant electronics differences between the upstream and Uniguard diagnostic the downstream travel times. Because software Ultrasonic Meters do not depend on the kinetic energy from the field, very low Flow conditioner and flows can be detected.

3 Adjacent spool pieces Assure measurement and Ultrasonic Flow Meters operational integrity Based on performance, reliability and availability the patented single and Advanced path configuration double reflection paths have proven to Dynamic flow profile correction be the standard in custody transfer gas Extended diagnostic functions measurement systems. series is the most accurate and flexible Ultrasonic Ultrasonic noise suppression meter for custody transfer applications Application Related Path and our single and double reflective path Substitution (ARPS) technology delivers unparalleled flow velocity recognition and range.

4 High-pressure calibration Meters are available in sizes ranging Material certificates: from 4" to 64" with a turndown ratio EN 10204 - , NACE MR-01-75 as high as 100:1 and can be used in bi-directional applications. No moving parts No pressure drop Fit for Purpose with ISO CD17089 compliant Integrity in Measurement AGA-9 compliant In practice, there are no simple solutions and a one size fits all solution cannot Highest noise immunity be optimal. Ultrasonic gas flow meter Highest repeatability applications have expanded considerably since their introduction over two decades ago.

5 Tougher applications demand technically advanced solutions and Elster Instromet continues to meet the challenge. The 4th generation Ultrasonic Meters produced by Elster Instromet today are the most sophisticated on the Ultrasonic Gas Flow Meters 03 Elster Instromet market and contain many advancements. The line of Ultrasonic flow Meters are the only ones featuring extended diagnostics with the possibility of detecting fouling and Ultrasonic flow pattern recognition. Cost Advantages &. Installation Savings Maintenance Savings: Because of no pressure drop and high Ultrasonic Meters with no moving parts The optional retractable transducer rangeability, Ultrasonic Meters can have and rugged, field tested design have design cuts down on the cost of a beneficial impact on installation capital a real maintenance cost advantage maintenance and installation by expenditures.

6 Over the life of the metering application. allowing removal of transducers Ultrasonic Meters can also communicate under flowing pressure without In the example below, twelve 12 orifice their diagnostics remotely, saving the need for block valves or meter runs were replaced by one 18 . maintenance time and expense. bypass lines. Ultrasonic meter. The cost savings for the Ultrasonic installation were in excess of $850, Before After Ultrasonic Gas Flow Meters 04 Elster Instromet Ultrasonic Expertise User Interface Long-term Stability Our Guarantee UNIFORM the most used Ultrasonic Regular verification is mandatory Elster Instromet not only provides the Flow Meter (USM) interface now available to maintain accuracy of a metering highest quality, best performing Ultrasonic for monitoring Series-IV electronics.

7 The system, but contributes heavily to the Meters but also a wide range of technical communication capabilities include four operational cost of the system. The solutions using an unprecedented range independent serial ports and allows verification intervals depend mostly of products and services. parameter setting "on the fly". on the primary flow measurement Elster Instromet products and solutions element and indirectly on the Upgrades of software can be simply support is among the most experienced measurement technology.

8 Downloaded while parameters and in the world. logged data are preserved. The graph above confirms the excellent repeatability, which is the key to accurate Data logging: more than 35 days measurement, and long-term stability of hourly records of an Elster Instromet USM which, due to the unique path configuration, is even Path substitution: calculates failing able to monitor its performance in the path value based on historic process itself. ratio's of your application Verification and audit trail: traceability of parameter settings and alarm listing Data security: 5 levels of password protection available now Integration algorithm.

9 Recent research of distorted flow profile effects results in improved characterization of flow profile properties and reduces measuring errors due to installation effects Ultrasonic Gas Flow Meters 05 Elster Instromet Ultrasonic Advancements Transducer Technology Diagnostics Coded Multiple Burst Elster Instromet 's proprietary transducer The Elster Instromet meter design allows Coded Multiple Burst (CMB) technology designs have been the vital element two major diagnostic capabilities: to help solve noise problems.

10 Enabling Elster Instromet Meters Regulating valves create line noise to perform to the highest industry Snapshot Diagnostic whose frequencies often fall in a meter's standards. The high efficiency and checks USM operation within accuracy Ultrasonic range. Part of the energy power of these devices enable the use specifications via extensive self testing. created during pressure reduction is of longer path lengths with multiple It allows the operator not only to examine transferred into acoustic energy, which reflections, resulting in unmatched flow signal waveform and amplitude but also, can lower the meter signal-to-noise ratio velocity recognition and range.
