Haimo Water Cut Meter (WCM) uses a Dual Gamma Meter (using a gamma source of extremely low activity as to be exempt per IAEA standards) and determines the Water Cut (WC) in three phase (oil+water+gas) flow up to 90% GVF. The meter is independent of oil / water emulsion effect.

APPLICATIONS
Water cut monitoring
Onshore and offshore
BENEFITS
Reduce costs of field development
Remote and automated operation
Acquisition of real-time data
Exemption Source based WCM consists of detector, meter body, gamma source and cabinet and data processing unit.
WCM is based on the principle that different materials have different absorption ability to gamma ray. The exempted gamma source is able to emit multiple energy levels gamma ray, and WCM uses two of them, namely high energy and low energy level gamma ray. Based on the absorption of the two gamma rays, two equations could be established and phase fractions could be solved. WCM is a non-contact type of meter which means the sensor (radiate source and detector) do not need to contact the medium being tested.
WCM could be used for Water Cut measurement in oil/water two phase flow or for both WC and GVF measurement in oil/water/gas three phase flow.
