Manifold operation

Improper installation or operation of manifolds may result in process leaks, which may cause
death or serious injury.
Always perform a zero trim on the transmitter/manifold assembly after installation to eliminate
any shift due to mounting effects. See
Three and five-valve configurations shown:
In normal operation the two block
valves between the process and
instrument ports will be open and the
equalizing valve will be closed.
1.
Hardware Installation
Align the Conventional Manifold with the transmitter flange. Use the four manifold
bolts for alignment.
Finger tighten the bolts, then tighten the bolts incrementally in a cross pattern to final
torque value. See "Flange bolts" on page 36
and torque values. When fully tightened, the bolts should extend through the top of
the sensor module housing.
Leak-check assembly to maximum pressure range of transmitter.
To zero the Rosemount 2051,
close the block valve to the
low pressure (downstream)
side of the transmitter first.
