LD303 - Operation and Maintenance Instruction Manual
1.8
Existing standards for the manifolds have also been taken into account, and standard designs fit
perfectly to the transmitter flanges.
Should the process fluid contain solids in suspension, install valves or rod-out fittings at regular
intervals to clean out the pipes.
The pipes should be internally cleaned by using steam or compressed air, or by draining the line
with the process fluid, before such lines are connected to the transmitter (blow-down). Do not allow
steam to enter the measuring chamber. Observe operating safety rules during wiring, draining or
blow-down
.
Some examples of installation, illustrating the position of the transmitter in relation to the taps, are
shown in Figure 1.3. The location of pressure taps and the relative position of the transmitter are
indicated in Table 1.1.
