Design Philosophy and Principle of Operation

Haimo LiveFlo FR is a combination of a gas / liquid two phase flow meter and a three phase water cut meter.

Measurement of the gas and liquid flow rates is carried out in the gas / liquid two phase meter that consists of a venturi and a single gamma meter. The Water Liquid Ratio (WLR) is measured with the dual gamma meter which is located downstream of the flow conditioner.

The phase fractions are derived from these two independent measurements and net oil flow rate is finally calculated using the gross liquid flow rate and water cut measurement.

In general, the Water Liquid Ratio (WLR) measurement accuracy deteriorates  with slugging as well as very high Gas Volume Fraction (GVF), therefore in order to measure WLR accurately Haimo has introduced a flow conditioner upstream of the dual energy gamma water cut meter to condition the multiphase flow by mitigating slugs and reducing the higher GVF level. This helps achieve the water cut measurement error within ±2% absolute for the full range of stated GVF in the meter’s operating envelope.

Full Range Multiphase Flow Meter (MPFM)

Total flow rate of the multiphase stream is measured by the venturi flow meter. Gamma ray technology is used to measure phase fractions, GVF and WLR respectively. A patented inline sampler helps to decrease gas fraction in the multiphase flow and enables accurate WLR measurement even at extremely high GVF. The multivariable transmitter (MVT) measures pressure, temperature and differential pressure. The pulses from the gamma meters are processed by a new design of high-frequency transmitter. A Data Acquisition Unit (DAU) performs all calculations and converts flow measurements from line to standard condition.
