Testing Of Two 10-Inch Insertion Propeller Flow Meters, Stuart Styles, Sierra Layous, Jack Evans Sep 2020

Testing Of Two 10-Inch Insertion Propeller Flow Meters, Stuart Styles, Sierra Layous, Jack Evans

BioResource and Agricultural Engineering

With funding from the US Bureau of Reclamation, California – Great Basin Region (Region 10), the Cal Poly Irrigation Training & Research Center (ITRC) conducted flow measurement accuracy testing on two 10-inch insertion (strap-on saddle) McCrometer Water Specialties propeller flow meters. Both meters were new and recently purchased by Westlands Water District. One of the meters is shown in Figure 1. Testing was performed at the ITRC Water Resources Facility (WRF) using the ITRC volumetric tank as the standard flow rate measurement for all tests. The ITRC volumetric tank was calibrated with the NIST1-traceable ITRC gravimetric tank using …


Magnetic Flow Meter Testing, Stuart Styles, Sierra Layous, Jack Evans Sep 2020

Magnetic Flow Meter Testing, Stuart Styles, Sierra Layous, Jack Evans

BioResource and Agricultural Engineering

With funding from the US Bureau of Reclamation, California – Great Basin Region (Region 10) and the California Department of Water Resources (Agreement No. 4600011908), the California Polytechnic State University, San Luis Obispo Irrigation Training & Research Center (ITRC) conducted testing on 4-inch and 10-inch spool-type magnetic flow meters ( also known as mag meters and electromagnetic flow meters) from six manufacturers (12 meters total). The testing was performed to assess the effects of various hydraulic conditions on meter accuracy.

Testing Of Two 10-Inch Insertion Magnetic Flow Meters, Stuart Styles, Sierra Layous, Jack Evans

BioResource and Agricultural Engineering

With funding from the US Bureau of Reclamation, California – Great Basin Region (Region 10), the Cal Poly Irrigation Training & Research Center (ITRC) conducted flow measurement accuracy testing on two 10-inch insertion (saddle-mount) McCrometer Mc Mag3000 magnetic flow meters. The meters were two of 360 new meters that were purchased by Westlands Water District. One of the meters is shown in Figure 1. Testing was performed at the ITRC Water Resources Facility (WRF) using the ITRC gravimetric (weigh) tank as the standard flow rate measurement for all tests. The ITRC gravimetric tank has a NIST1-traceable uncertainty of …


Testing Of Two 30-Inch Magnetic Flow Meters, Stuart Styles, Jack Evans, Sierra Layous, Chad Tenbrink Aug 2020

Testing Of Two 30-Inch Magnetic Flow Meters, Stuart Styles, Jack Evans, Sierra Layous, Chad Tenbrink

BioResource and Agricultural Engineering

With funding from the US Bureau of Reclamation, California – Great Basin Region (Region 10), the Cal Poly Irrigation Training & Research Center (ITRC) conducted flow measurement testing on two (2×) 30inch spool-type magnetic flow meters in March of 2020. Figure 1 shows the meters installed at the testing facility. The testing determined the accuracy for each test meter in a straight pipe configuration across a range of typical water velocities (0.4 to 3.8 feet per second). Testing was performed at the ITRC Water Resources Facility (WRF) using the ITRC volumetric tank as the standard flow rate measurement for all …


Testing Of A 10 To 48-Inch Insertion Magnetic Flow Meter, Stuart Styles, Jack Evans, Sierra Layous, Chad Tenbrink Aug 2020

Testing Of A 10 To 48-Inch Insertion Magnetic Flow Meter, Stuart Styles, Jack Evans, Sierra Layous, Chad Tenbrink

BioResource and Agricultural Engineering

With funding from the US Bureau of Reclamation, California – Great Basin Region (Region 10), the Cal Poly Irrigation Training & Research Center (ITRC) conducted flow measurement testing on one (1×) 10 to 48-inch Seametrics EX21x insertion magnetic meter (“Seametrics”, “test meter”) in April 2020. Figure 1 shows the meter installed at the testing facility. The testing determined the accuracy of the test meter in a straight pipe configuration across a range of typical water velocities (0.5 to 5.8 feet per second). Testing was performed at the ITRC Water Resources Facility (WRF) using calibrated measurements from a 30-inch Krohne Enviromag …


Assessing Laser Lifetime Test Performance, Joe Weichman, Hamid Hemmati, Malcolm Wright Aug 2011

Assessing Laser Lifetime Test Performance, Joe Weichman, Hamid Hemmati, Malcolm Wright

STAR Program Research Presentations

Assessing expected component lifetime is necessary in developing instruments for future space-flight projects to ensure long term operation in the challenging environment. Although semiconductor diode lasers have widespread use in terrestrial applications, their use in space is still an emerging technology that requires on-going testing to demonstrate their capability. The project called for re-establishing the test setup for assessing lifetime performance of 20 continuously running 200mW 830 nm diode lasers. These lasers underwent previous testing based on parameters for NuSTAR’s laser metrology system, and met the six month lifetime project requirements under nominal operating conditions. Laser testing is currently underway …

Measurement And Analysis Of Truck And Rail Shipping Environment In India, Sher Paul Singh, A. P. S. Sandhu, Jay A. Singh, E. Joneson

Industrial Technology and Packaging

Free trade agreements have been on the rise in all regions of the world in the past decade. This has allowed for global distribution and marketing of products in an international market. Products once produced for domestic markets must now be able to compete in international markets without trade barriers. Increased international commerce and manufacturing have forced many packaging and logistics engineers to broaden their true understanding of the global distribution environment. India is a recent entrant on the global arena for manufacturing and services. While China’s economic developments have dominated global headlines, India’s own growth has been impressive as …
