Flow Measurement a. For each sewer of a Party that has, or is expected to have, a discharge of 60,000 GPD or greater which discharges from a sewer of the District, Fairfax or WSSC into a sewer owned or operated by the District, DC Water, Fairfax or WSSC; the owner/manager of such discharging sewer(s) shall provide and install wastewater flow meters of the maximum practicable accuracy, at its own expense. The receiving Party directly involved shall mutually approve all such meter installations, shall designate who shall read, test, operate and maintain all such meters, and shall determine the methods and procedures to be followed. DC Water, Fairfax and WSSC may jointly read, test and inspect such meters at reasonable times at the request of any Party.
Flow Measurement. The measured average daily and maximum daily flow, in gallons per day, to the POTW from regulated process streams and other streams.
Flow Measurement. For flow measurement several types of instruments can be used - differential pressure devices, area meters, positive displacement meters, sonic meters, vortex meters, turbine meters, magnetic meters, coriolis, etc. For specific information and further guidance on the selection of Flow measuring devices please see the following specifications: 5578-E2-SP-IE-00001, Flow Instruments 5578-E2-SP-IE-00002, dp type Flow Elements and Meter Runs
Flow Measurement. The calibration of gas flowmeters or flow measurement instrumentation shall be traceable to national and/or international standards. The maximum error of the measured value shall be within ± 2 per cent of reading.
Flow Measurement. 6 CAP water transported for AWBA pursuant to this Agreement shall be measured at or near 7 the Point of Delivery in accordance with requirements of maintaining the accuracy of these 8 systems within plus or minus five (5) percent of actual flows.
Flow Measurement. EXXONMOBIL, at its sole expense, shall install, operate and maintain any flow measuring facilities designated by the CITY’S Public Works Director (“Director”), for the purpose of measuring the flow of the EXXONMOBIL industrial wastewater discharge being conveyed to the Point of Compliance described in Section 3. EXXONMOBIL shall keep said facilities in good operating condition at all times. The flow measuring facilities shall accurately and continuously indicate and transmit to the CITY’S wastewater treatment plant the rate of flow and volume of all Industrial Wastewater discharge at the Point of Compliance.
Flow Measurement. A User, when required by the District or the City Engineer, shall install and maintain a flow measurement device for instantaneous rate and/or cumulative flow volume determinations. Metered water supply may be used in lieu of flow measurement devices if it can be documented that the water usage and waste discharge are the same, or where a measurable adjustment to the metered supply can be made to determine the waste volume. Meters and flow records shall be maintained at the User’s expense in good operating condition at all times. The User shall notify the District in writing within five (5) days in the event that the User becomes aware that the meter or flow recorder has failed to accurately register the flow. The User shall also notify the District of the User’s intention to alter the installation of a meter or flow recorder so as to affect the accurate recording of industrial waste entering the Facilities.
Flow Measurement. Geothermal Fluid flow measurement is required for the Binary Plant (and each unit if more than one provided), and on the dump flow to the Wairakei stream. Currently, the total flow is not measured by a single meter. Instead it is calculated by using a number of flow meters at various points in the Geothermal Fluid System and assumptions made for volumes flowing through two take-off points. A meter measuring total flow will therefore be required to be installed by the Contractor for input into the Binary Plant control system. The bypass flow shall be calculated by subtraction of the binary unit flows from the total Geothermal Fluid flow. The bypass flow shall be shown on the control screens and totalised in the reports (for assessment of lost generation potential). The flow to the reinjection system shall be calculated by subtraction of the Prawn Farm flow and dump flow from the total Geothermal Fluid flow. The effects of scale forming within the Geothermal Fluid path shall be taken into account when selectiing flow measuring instruments.
Flow Measurement. The calibration of gas flow-meters or flow measurement instrumentation shall be traceable to national and/or international standards. The maximum error of the measured value shall be within ±2 per cent of reading. For partial flow dilution systems, the accuracy of the sample flow GSE is of special concern, if not measured directly, but determined by differential flow measurement: GSE = GTOTW – GDILW In this case an accuracy of ±2 per cent for GTOTW and GDILW is not sufficient to guarantee acceptable accuracies of GSE. If the gas flow is determined by differential flow measurement, the maximum error of the difference shall be such that the accuracy of GSE is within ±5 per cent when the dilution ratio is less than 15. It can be calculated by taking root-mean-square of the errors of each instrument.
Flow Measurement. 5 17.1 City shall, at its sole expense and with the approval of the Authorized Representatives, construct, install and maintain in accordance with manufacturers' specifications for the specific 6 application, a flow measurement system and communications interface at each Point of 7 Receipt and each Point of Delivery compatible with Association telemetry requirements. The Authorized Representatives may waive or reduce the requirements of this Section 17.1 for 8 any Point of Receipt or Point of Delivery for which they deem the requirements excessive with respect to the quantity of water to be taken at that Point of Receipt or Point of Delivery. 10 and detection device) as close to zero error as practical, but in no event shall error exceed plus or minus five percent (5%) of actual flow except when the flow being measured is to a 11 City water treatment plant (WTP) operating at thirty percent (30%) or less of maximum operating capacity. In such circumstances, the accumulated volume delivered to a WTP 12 during the periods of exception in a calendar year shall not exceed six percent (6%) of the total volume delivered to that WTP during that calendar year. City shall prepare and regularly 13 implement testing and recalibration procedures for the flow measurement systems, which procedures must be approved by the Authorized Representatives. At least once every six 14 months, unless otherwise agreed by the Authorized Representatives, City shall recalibrate its 15 flow-measuring system as close to zero error as practical, but in no event shall error exceed plus or minus five percent (5%) of actual flow except as provided above in this Section. City 16 shall notify Association of when such recalibration is planned so that Association may observe the procedure. Association may at reasonable times, at its sole expense and after reasonable 17 notice to City, test or have tested the flow-measuring system to determine its accuracy. Association may discontinue service to City hereunder during any period of noncompliance 18 with this Section unless City agrees to accept Association's billing and water accounting pursuant to Section 17.3. 17.3 In the event that water accounting records or any routine or special test of the flow 20 measurement system discloses an annual volume, or a flow measurement error, that exceeds the limits provided in Section 17.2, all bills and water accounting affected by such limits having 21 been exceeded may be adjusted by Association based on th...
