Installation Guidelines
IV. INSTALLING THE SENSOR
Having followed the installation guidelines in Section 2, “Installation Guidelines”, Subheadings I through III, you
may now proceed with installation.
CAUTION
1. Use proper eye protection and any other safety equipment as required by your installation site.
2. Check electrical power to ensure that all power has been disconnected
and ‘locked out’.
3. Ensure the process tank and/or line pressures are ‘zero’.
4. Ensure that steam, hot water, acids or any other potentially hazardous media will not be
released.
5. Follow all safety precautions as specified for your installation site and / or local codes.
1. Process Connections
•
Threads: Coat with a thin layer of thread tape or sealant/lubricant.
Do not overtighten threads when installing.
•
Flanges: To ensure a correct seal on mating flanges, mount and tighten flanges according
to ANSI standards.
2. Sensor Orientation
•
To optimize the sensor’s performance ensure the sensor is positioned as outlined below.
As shown in Figure 13 below, ensure the
arrows etched on the sensor flats
( ) are oriented
parallel to the process flow. Blue arrows indicate the acceptable directions of the flow.
Notes: 1.
Liquids & Slurries: When mounted in a tee or section of pipe larger than the normal process pipe,
position sensor at a sufficient insertion point so as to avoid contact with any air or gas bubbles that
occur in the larger section of pipe.
2.
Avoid locations where sediment may accumulate and eventually isolate the sensing tip from the
process. Sediment covering the sensor tip may prevent the switch/transmitter from being able to
sense any changes in the process as the sediment will insulate the sensing tip.
