Mounting the EchoSonic® II
The sensor should always be mounted perpendicular to the liquid surface using the
provided Viton® mounting gasket. Insure that there are no restrictions or obstacles in the
path of the ultrasonic signal. Further mounting information can be found on the Flowline
website at
www.flowline.com .
The EchoPod® has a 1” NPT or G fitting and requires more care in mounting to reduce any
coupling of the ultrasonic signal to the mounting structure. The below listed fittings are
recommended.
For installations in existing 2” fittings:
1) Use a LM52‐1400 2” thread x 1” thread adapter (shown to
the right) or a LM52‐1410 2” slip x 1” thread adapter.
(An adapter with an air gap around the 1 inch threads as
shown is recommended)
For installations in plastic tanks (use one of the following):
1) Use a 1” Bulkhead fitting, such as the LM52‐1890 Bulkhead
fitting.
2) Use a larger Bulkhead fitting, such as the LM52‐2890 in
combination with a reducer bushing such as the LM52‐1400.
3) Weld a plastic 1” half coupling to the tank top.
For installations in metal tanks (use one of the following):
1) Use the recommended bulkhead fittings as shown above.
2) Use a flange with a 1” riser, such as the LM52‐1850 (the
thread is above the plane of the flange). Do not use a blind
flange with a tapped 1” thread.
3) Use a larger flange with a 2” thread and add a reducer
bushing such as the LM52‐1200.
Note: While installations directly into a 1”metal fitting are not
recommended, acceptable results may be obtained if the 1”
fitting is a half coupling in form and the outer diameter of the
coupler is tightly wrapped in vinyl tape to dampen vibrations.
For installations in open tanks and sumps:
1) Use Flowline's LM50‐1001‐1 side mount bracket.
