INTRODUCTION

Two 16" Wall Tap Flow Nozzle Meter Runs, Serial Numbers 158458/FEI 101/1395 and 158459

/1102/1398, were calibrated at the Alden Research Laboratory, Inc. (Alden) for Omaha Public Power

District under their Purchase Order Number 00077262, using Alden's standard test procedures, QA-

AGF-7-86, Revision 6. Flow element performance is presented as discharge coefficient, C, versus

pipe Reynolds number, in both tabular and graphical format for two tap sets.

FLOW ELEMENT INSTALLATION

The flow meters were installed in Test Line 2 in the Allen Facility, which is shown in plan view on

Figure 1. A pair of centrifugal pumps (300 horsepower each) provide a maximum head of about 150

ft and a maximum flow of about 44 ft3/s. Water was provided from a heated 180,000 gallon sump

under the test floor.

The detailed piping arrangements used for the calibrations, immediately upstream and downstream

of the flow element, are shown in Figure 2, including all significant fittings and pipe lengths.

Careful attention was given to align the flow element with the test line piping, and to assure no

gaskets between flanged sections protruded into the flow. Vents were provided at critical locations

of the test line to purge the system of air. A specially fabricated elbow was included downstream

of the meters to simulate field conditions

TEST PROCEDURE

The test technician verified proper installation of the flow element in the test line prior to introducing

water into the system to equalize test line piping and primary element temperature to water

temperature. After attaining thermal equilibrium, the test line downstream control valve was then

closed and vent valves in the test line were opened to remove air from the system. With the line flow

shut off, the flow meter output was checked for zero flow indication.

Prior to the test run, the control valve was set to produce the desired flow, while the flow was

directed to waste. Sufficient time was allowed to stabilize both the flow and the instrument readings,

after which the weigh tank discharge valve was closed and the weigh tank scale indicator and the

electric timer were both zeroed. To begin the test run, flow was diverted into the weigh tank, which

automatically started the timer.

At the start of the water collection, a computer based data acquisition system was activated to read

the meter output, such that the meter output was averaged while the weigh tank was filling. At the

end of the run, flow was diverted away from the weigh tank and the timer and data acquisition

system were stopped to terminate the test run. The weight of water in the tank, elapsed time, water

temperature, and average meter output were recorded on a data sheet. The data were entered into

the computer to determine the flow and the results were plotted so that each test run was evaluated

before the next run began. The control valve was then adjusted to the next flow and the procedure

repeated.

FLOW MEASUREMENT METHOD

Flow was measured by the gravimetric method using tanks mounted on a scale having a capacity

of 100,000 pounds with a resolution of 2 lbs. Water passing through the flow element was diverted

into the tank with a hydraulically operated knife edge passing through a rectangular jet produced by

a diverter head box. A Hewlett-Packard 10 MHz Frequency Counterwith a resolution 0.001 sec was

started upon flow diversion into the tank by an optical switch, which is positioned at the center of

the jet. The timer was stopped upon flow diversion back to waste and the elapsed diversion time was

recorded. A thermistor thermometer measured water temperature to allow calculation of water

density. Volumetric flow was calculated by Equation (1).

B = buoyancy correction, I PaPw

IbmP = air density, -ift -

The buoyancy correction includes air density calculated by perfect gas laws with the standard

barometric pressure, a relative humidity of 75%, and measured air temperature. The weigh tank is

periodically calibrated to full scale by the step method using 10,000 Ibm of cast iron weights, whose

calibration is traceable to NIST. Flow calculations are computerized to assure consistency. Weigh

tank calibration data and water density as a function of temperature, are stored on disk file. Data

were recorded manually and on disk file for later review and reporting.

DISCHARGE COEFFICIENT CALCULATIONS

Discharge coefficient, C, is defined by Equation (2) and plotted versus pipe or throat Reynolds

number. The discharge coefficient relates the theoretical flow to the actual flow.

The theoretical proportionality constant, KM, between flow and square root of differential head is a

function of the meter throat area, the ratio of throat to pipe diameter;and the local gravitational

constant, as defined by Equation (3).

FLOW METER SIGNAL RECORDING

The secondary element, which converts the primary element signal into engineering units, was one

of several "Smart" differential pressure transmitters having ranges of 250" W.C., 1000" W.C. and

100 psid. Each transmitter was calibrated with a pneumatic or a hydraulic dead weight tester having

an accuracy of 0.02% of reading. Transmitter signals were recorded by a PC based data acquisition

system having a 16 bit A to D board. Transmitter calibrations were conducted with the PC system

such that an end to end calibration was achieved. Transmitter output was read simultaneously with

the diversion of flow into the weigh tank at a rate of about 34 Hz for each test run (flow) and

averaged to obtain a precise differential head. For primary elements with multiple tap sets,

individual transmitters were provided for each tap set and all transmitters were read simultaneously.

Average transmitter reading was converted to feet of flowing water using a linear regression analysis

of the calibration data and line water temperatures to calculate appropriate specific weight.

TEST RESULTS

The results are presented in tabular and graphical format. The measured values of weight, time, and

.line temperature, which are used to calculate the listed flow, are shown in the tables. The average

transmitter reading used to calculate the differential head in feet of water at line temperature is also

Alden Report 080-05/C I 160 Page 6 of 29

shown in the tables. Flow meter performance is given as the discharge coefficient versus pipe

Reynolds number for both tap sets. The discharge coefficient was measured over a test range of

Reynolds numbers shown in the table below.

158458/FE1101/1395 FW145-FW146 & FW612-FW6I1 985,300 3,346,700

Mr. Neil Florentine of Westinghouse witnessed the tests.

As the operating Reynolds number exceeds the capability of the test facility, the discharge coefficient

at operating conditions must be estimated. The extrapolation utilizes the ASME MFC-3M 1988

Equation (32) page 35 describing discharge coefficient versus pipe Reynolds number as shown by

equation (5).

C = 0.9975- 0.00653( 106J (5)

The deviation of the measured coefficient from the equation value was calculated at each test

Reynolds number. The average deviation was used calculate the discharge coefficient at any

Reynolds number by equation (6).

C = 0.9975- 0.0065 + AClj0 (6)R D

Tables are given indicating the measured coefficients versus Reynolds number, predicted coefficients,

deviations, and average deviation over the test range. Plots of test data, predicted coefficients, and

extrapolated coefficients are shown for each meter.

Analysis shown in the following tables an plot of uncertainty versus Reynolds number indicates that

the flow measurement uncertainty is better than 0.15% at the 95% confidence level. Calibrations of


of the test instrumentation (temperature, time, weight, and length measurements) are traceable to the

National Institute of Standards and Technology (formerly the National Bureau of Standards) and

Alden's Quality Assurance Program is designed to meet ANSI/NCSL Z540-1-1994 "Calibration

Laboratories and Test Equipment-General Requirements" (supercedes MIL-STD-45662A).

Thermal Expansion Factor

The dimensions of a differential producing flow meter are affected by the operating temperature,

requiring a Thermal Expansion Factor (F.) to be included in the calculations. The calculation

requires the temperature at which the meter dimensions were measured be known. If this

information is not available, an ambient temperature of 68"F is assumed. The Thermal Expansion

Factor is calculated according to the American Society of Mechanical Engineers Standard ASME

MFC-3M-1989, Equation 17 (pg 11).

a= 1+ 2 (acc _4as a)(t- tme.)

where = ratio of throat diameter to pipe diameter, dimensionlessaPE = thermal expansion factor of primary element, TFap = thermal expansion factor of pipe, 'Ft = temperature of flowing fluid, 'Ftmnas = temperature of measurements, *F

Thermal expansion factors, a, excerpted from MFC-3M-1989, are listed in the Table below for six

typically used materials at three temperatures. Linear interpolation is used to determine the

coefficients at flowing temperature.
