FLOW METERING DEVICE
First Claim
1. A fluid flow metering device comprising:
- a ball valve locatable in the fluid flow, having at least two transverse bores through the ball valve, a first transverse bore and a second transverse bore;
the first transverse bore including a fluid flow metering apparatus for measuring the rate of fluid flow through the first transverse bore;
the ball valve being rotatable between a first metering position where fluid is flowable through the first transverse bore and a second open position where fluid is flowable through the second transverse bore; and
the second transverse bore being dimensioned so that a tool is movable through the second transverse bore when the ball valve is in the second open position.

Abstract
A fluid flow metering device comprises a ball valve locatable in a fluid flow, having at least two transverse bores through the ball valve, a first transverse bore and a second transverse bore. The first transverse bore includes a fluid flow metering apparatus for measuring the rate of fluid flow through the first transverse bore. The ball valve is preferably rotatable between a first metering position where fluid is flowable through the first transverse bore and a second open position where fluid is flowable through the second transverse bore. In addition, the second transverse bore is dimensioned so that a tool is movable through the second transverse bore when the ball valve is in the second open position.

13. A method for measuring fluid flow, the method comprising the steps of:
-
positioning a ball valve in a fluid flow, having a first transverse bore and a second transverse bore through the ball valve, the first transverse bore including a fluid flow metering apparatus; rotating the ball valve to a first metering position where fluid is flowable through the first transverse bore; measuring the fluid flow rate of the fluid moving through the first transverse bore by means of the fluid flow metering apparatus; and rotating the ball valve to a second open position where fluid is flowable through the second transverse bore, the second transverse bore being dimensioned so that a tool is movable through the second transverse bore, when the ball valve is in the open position. - View Dependent Claims (14, 15, 16, 17)
