Abstract

A manifold which mounts a transmitter to a pipeline comprises a body of rectangular-like shape. The body has a first surface and a second surface at right angles to the first surface. The second surface of the body includes a first and second input port, and the first surface of the body includes corresponding first and second output ports. The body also includes a first and second channel internal to the body such that fluid is conducted between the first input port and the first output port, and fluid is conducted between the second input port and the second output port. The body further includes an internal crossover channel between the first channel and the second channel. A first and second valve is included for controlling the conducting of fluid in the first channel and the second channel, respectively. A third valve is included which controls the flow of fluid in the internal crossover channel.

Claims

1. A manifold for mounting a transmitter to a pipeline, said pipeline having fluid flowing therein, said pipeline further having a first and second process pipe to couple said fluid to said transmitter, said manifold comprising:

a) a body of rectangular-like shape having a height, length and width having a first surface formed by the plane of the width and length and having a second surface at right angles to said first surface formed by the plane of the length and height, and further wherein the second surface includes a first and second input port, and the first surface includes corresponding first and second output ports, the body including a first and second channel internal to the body such that fluid from the first process pipe is conducted from the first input port to the first output port and fluid from the second process pipe is conducted from the second input port to the second output port, the body further including an internal crossover channel between the first channel and the second channel;

b) a first and second valve, the first valve controlling the flow of fluid in the first channel and the second valve controlling the flow of fluid in the second channel, the first and second valve being placed between the internal crossover channel and the first and second output port, respectively;

c) a third valve for controlling the flow of fluid in the internal crossover channel; and

d) a vent drain valve, the valve controlling the flow of fluid from the first channel to the outside of the body, the vent drain valve being placed in a vent channel, the vent channel being between the first input port and the internal crossover channel, and the outside of the body.

2. A manifold according to claim 1 wherein said transmitter includes a coplanar meterbody.

3. A manifold according to claim 3 wherein said coplanar meterbody further comprises:

a) a header coupled to said meterbody, having a first and second input port, the first surface of the manifold mounting on the header, such that the first and second output ports of the manifold are opposite the first and second input ports of said header.

4. A manifold according to claim 3, wherein said second surface of said manifold mounts to said first and second process pipe in accordance with a predefined pattern spacing and a predefined mounting mechanism, such that the first and second input ports of said manifold and corresponding mounting mechanism of the manifold correspond to the predefined pattern spacing.
