Level Controller Overview and Installation

GENERAL INSTALLATION
CONSIDERATIONS

The accuracy of a level control measurement depends upon proper
installation of the controller and impulse piping. The piping between
the process and the controller must accurately transfer the pressure in
order to obtain accurate measurements.

Mount the controller close to the process and use a minimum of impulse
piping to achieve best accuracy. Keep in mind, however, the need for
easy access, safety of personnel, and a suitable controller environment.
(Refer to Figure 2-6 for Level Controller dimensions.) In general, install
the controller so as to minimize vibration, shock, and temperature
fluctuations.

The high pressure side of the level controller must always be plumbed
to the bottom of the tank. For open vessels, the low pressure side of the
Level Controller should be vented. For closed vessels, the low pressure
side must always be plumbed to the top of the tank.

The following sections discuss the factors to consider for a successful
Level Controller installation.
