Conduit Entry Plugs And Adapters; Tables Table 1 - Conduit Entry Plugs - Honeywell SmartLine ST700 Installation Manual

Flush Mounting
To mount a flush mounted transmitter model, cut a hole for a 1-inch standard pipe in the
tank or pipe where the transmitter is to be mounted. See
Weld the 1-inch mounting sleeve to the wall of the tank or to the hole cut on the pipe.
Insert the meter body of the transmitter into the mounting sleeve and secure with the
locking bolt. Tighten the bolt to a torque of 6.4Nm ±0.30Nm [4.7ft.-lbs. ±0.2ft.-lbs.]
Once the transmitter is mounted, the transmitter housing can be rotated to the desired
position. See Figure 7.

Quick Start Installation Guide
Remote Seal Mounting
Mount the transmitter at a remote distance determined by length of capillary tubing.
Note: The combination of tank vacuum and high pressure capillary head effect should
not exceed 9psi (300mm Hg) absolute.
On insulated tanks, remove enough insulation to accommodate the mounting sleeve.
Example – Typical Remote Seal Transmitter installation.
Figure 8
Note: For Sanitary 3-A installations, only mount the transmitter outside of the Non-
Product Contact area where incidental contact with the process material is unlikely,
use a minimum capillary length of 1.5m (5ft.)
