Title:
MASS FLOW METER
Document Type and Number:
WIPO Patent Application WO1993005366
Kind Code:
A3
Abstract:
The invention relates to an apparatus for continuously determining the variation in weight of fluent bulk material and more particularly, in detritus in drilling fluid discharged during a well drilling operation where drilling fluid discharged from the borehole is passed through a shale shaker (5) to remove the detritus. The apparatus has a plurality of receptacles (82), each of which are supported on a device (84) for sequential movement to and through a detritus receiving position. A mesuring device (90) is operatively connected to measure the weight of detritus collected in a selected receptacle and produces an output in response to the weight of detritus measured. A lock device (92) is operatively associated with the supporting device for maintaining a selected receptacle in the receiving position for receipt of detritus, the lock device being releasable when the weight in the selected receptacle reaches a predetermined weight to allow the support device to move under the weight of detritus in the receptacle away from the receiving position while at the same time a receptacle moves into the receiving position.
