The Haimo full range multiphase flow meter 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 sl ing 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.

Features:

Best in class for water cut measurement – a key factor in resulting net oil accuracy
Flow regime independent
Wide operating range with low pressure drop
Non–intrusive and in–line measurement techniques
Field oriented design, small footprint and cost effective mobilization
Compact, robust and easy to install meter –ideal for remote locations
High frequency data acquisition, provides real time well data at line and standard conditions
