What make Gas different

ITS COMPRESSABLE

So what does that mean?

We need to know the angle of the beamWe need to know the path lengthWe need to know the internal diameter

We send two beams of sound and look for the time difference. From this Dt we establish the velocity of the gas.From the velocity and cross sectional area we can compute Volume in ACTUAL CUBIC FEET.


How do we install it



why you need to measure and install correctly

Dirty Gas = Bad Measurement12” pipe 0.1” build up internally Cross sectional change 113.09 to 111.22 =1.65%

Incorrect measurement of pipe will have the same errors


Why use ultrasonic meters on pipelines

No pressure drop = no cost of use

Recompression costs approx $68000/psi/year

Low installation cost

No fugitive emissions from installation


What variable effects the measurement most?

Temperature an 80 f increase or decrease in temperature will give you a 14.4% volume change.

Composition / compressibility factor will vary from 0.997 to .75 dependent upon composition , pressure and temperature This is the “ Z “ FACTOR

Pressure Pressure changes the Standard volume mostExample 900psi gas 900 + 14. 696 = 62.24 times compressibility 14.696


GAS FLOW = CASH FLOW

EXAMPLE 16” Meter 90000acf/hr(actual) Average flow Pressure 720psig (50 times compression) Temp 60f = 4.5mmscfhAssume gas price is $5.5/mscf Per Month 30 x 24 x 4,500 x 5.5 =$17,820,000/Month

0.1% error = $17,820/month or $213,840/year

Chromatograph

Analyzes composition to enable the calculation of BTU value and Super compressibility factor

Compressibility factor is dependent on P , T and Gas compositionValued typical are from 0.94 - 0.79
