An instrument manifold or data header is a length of pipe ported to receive various probes and measuring instruments. The instrument manifold should be rated to the maximum expected surface pressure. A dead weight tester (manual or electronic) measuring wellhead flowing pressure and a thermometer for wellhead flowing temperature can be installed. Wellhead samples can be obtained at the manifold and a port for chemical injection is provided. A sand detection probe, if required, would be installed in the data header. The instrument manifold should be located as close as possible to the surface control head and upstream of the choke manifold.
