摘要： A leak sensor for sensing fluid flow through the bearings and seals about a shaft extending from a prover. Any leakage of fluid through the bearings and seals will migrate into the annular cavity within a housing and surrounding the shaft. A conduit or passageway in fluid communication with the annular cavity conveys the leaking fluid into a collection chamber. A float within the collection chamber will trigger an electrical or mechanical signal when the float rises a preset distance. If electrical, the signal is transmitted to an alarm unit to trigger a warning indicative of the amount of fluid in the collection chamber.

摘要： A prover mounted upon a supporting lower framework includes a piston supporting rod extending longitudinally through a cylinder, which cylinder receives and discharges a fluid to measure the flow rate of the fluid by translation of the piston from the fluid receiving end to the fluid discharging end. Motive means supported on a frame mounted on the prover draws the rod toward the fluid receiving end of the cylinder. An upper framework is attached to the lower framework through a plurality of stanchions. Various I-beams formed as part of the upper framework enhance rigidity to the combination of lower framework and upper framework. The combination of lower framework and upper framework provides support for the prover in a horizontal or a vertical orientation without affecting the operation, repair or maintenance of the prover.

摘要： A self-flushing small volume prover apparatus, method and system for removing foreign materials. A piston can be configured with a valve arrangement located within a cylindrical object in order to permit fluid to pass through an annular passage when the piston travels from a downstream position to an upstream position. An inlet port and an outlet port can be located at the bottom of the cylindrical object. The outlet port can be welded at the bottom of the bore cylinder so that foreign material can flow directly out of the prover bore cylinder via the outlet port. The velocity of the piston can remove the collected foreign material from the bore cylinder via the outlet port, thus creating a self-flushing prover.

摘要： A small volume prover apparatus and method for precisely measuring the flow rate of a fluid via a cylindrical component such as a flow tube. A precision bore cylinder and a piston can be configured with a valve arrangement in order to permit fluid to pass through an annular passage when the piston travels from one position to an opposite position. An accelerometer sensor can be mounted to the piston for continuously detecting the velocity of the piston traveling in the pipe by integrating acceleration data with respect to time data. The volumetric flow rate can be automatically calculated by multiplying the velocity with respect to the area of the flow tube.

摘要： A prover includes a piston supporting rod extending longitudinally through a cylinder, which cylinder receives and discharges a fluid to measure the volume and flow rate of the fluid by translation of the piston from the fluid receiving end to the fluid discharging end. Motive means includes at least one element for drawing the rod and piston toward the fluid receiving end of the cylinder. Travel of the piston in the direction from the fluid receiving end to the fluid discharging end of the cylinder is sensed at discrete locations to provide an indication of the quantity of fluid therebetween and the related flow rate. Each of a plurality of switches, linear encoder or laser detector provides position sensing signals reflective of the volume and rate of fluid flowing in the cylinder. These signals, representative of this volume and flow rate, are compared with preset parameters to determine the degree of equivalence. Thereby, self testing and validation occurs.
