Abstract

A flow meter for determining the flow rate of a liquid or slurry flowing in a pipeline or similar conduit. The flow meter is capable of metering the flow of a multiple-phase medium such as a gas-oil combination from a sub sea oil well. The meter includes a tube-like J-bend member which is connected to the pipeline by a non-restricting, ring-type universal joint. The J-bend member is usually arranged with the member arranged in a horizontal plane with the member supported or suspended by a pair of load cells which are arranged 90.degree. apart and measure the reaction forces in a vertical and horizontal plane passing through the center of gravity. In this way, the load cells measure the weight of the J-bend member as well as the reaction moment produced by the liquid flow. In another embodiment the J-bend member is supported by a pair of rollers positoned 90.degree. to each other and arranged to suspend the J-bend member.
