Bill Johansen, P.E.

Director of Engineering & Flow Measurement Instructor

Bill Johansen
Bill is the Director of Engineering at CEESI and is licensed as a professional engineer in Wyoming, Colorado and Texas. Bill joined CEESI in 1996 as a staff engineer after graduating from the University of Wyoming with Bachelor and Master’s Degrees in Mechanical Engineering. Prior to entering college he had served in the US Navy as a nuclear reactor mechanic and operator. Bill currently oversees quality control of internal and customer calibrations for both the Colorado and Iowa calibration facilities. He directs how the technicians are to set up and perform meter and instrument calibrations, manages how calibration data reports are created for customers, and answers customer questions about calibrations. Bill directs efforts to improve customer meter calibrations by: improving and extending the range of gravimetric primary sensors, reducing the uncertainty of primary systems and data acquisition systems, adapting lab procedures and equipment to keep pace with current metering technologies, using Statistical Process Control (SPC) data to insure that laboratory equipment is correctly functioning, and training technicians to correctly understand new flowmeter electronics and software. Bill also works with the software development staff to ensure that new data acquisition, processing, and reporting software adheres to CEESI quality assurance procedures, industry standards, and customer requirements. Bill's work with the engineering staff at CEESI focuses on supporting and improving the quality of the calibrations at the Colorado and Iowa facilities. This work includes supporting the biannual National Voluntary Laboratory Accreditation Program (NVLAP) audits and the design and construction of the low flow calibration standard used at the Iowa calibration facility. Since Bill started working at CEESI, he has planned and taught a variety of flow measurement training courses. He has also written and presented papers at various industry conferences including the International Symposium on Fluid Flow Measurement (ISFFM) and the CEESI Ultrasonic Meter User’s Workshop.
