"Totalizing Flow Meter" or"TFM" means a meter associated with a Well that is designed <br /> and manufactured for the purpose of measuring the flow of water, has a totalizing feature <br /> in acre-foot measurements, and meets the requirements of Rule 16.5. <br /> 16. "Verification", "Verified", or"Measurement Method Verification" means the test performed <br /> by a Qualified Well Tester to verify the accuracy of a Well's method of measurement. <br /> 17. "Well Distribution System" means the pumping and piping systems through which the <br /> Well water is pumped. <br /> 18. "Well" means any structure or device used for the purpose or with the effect of obtaining <br /> ground water for beneficial use from an aquifer except those exempted under Rule <br /> 16.2A. <br /> 19. "Well User" means any Person diverting ground water. <br /> B. Any other term used in these Rules that is defined in sections 37-80-102, 37-80-104, 37-90-103, <br /> 37-90-107, 37-90-137 or 37-92-103, C.R.S., (as may be amended) shall have the same meaning <br /> given therein. <br /> C.

All <br /> measurement devices must be tamper-resistant. <br /> A. Totalizing Flow Meter(TFM) Method <br /> 1. Any meter that is designed and manufactured for the purpose of measuring the flow of <br /> water, and that has a totalizing feature in acre-feet, shall be considered to be acceptable <br /> for purposes of these Rules. A TFM installed prior to the Rules 2009 effective date, that <br /> reads in gallons and contains sufficient recording digits to assure that"rollover"to zero <br /> does not occur within two years, will be acceptable. The State Engineer may adopt <br /> written standards and specifications for the installation, calibration, testing, repair, and <br /> maintenance of meters. When a TFM is used, it shall be the Well User's responsibility to <br /> keep the meter in accurate operating condition. An installed TFM shall be deemed to be <br /> in accurate operating condition when the flow measured by the meter is within plus or <br /> minus 5% of an independent field measurement made using calibrated test equipment. <br /> The Division Engineer may order any meter that fails to meet this standard to be <br /> recalibrated or replaced. <br /> 3 <br />
