INSTALLATION

 

Step

 

Six

 

The

 

LVU2800

 

Series

 

should

 

always

 

be

 

mounted

 

perpendicular

 

to

 

the

 

liquid

 

surface

 

and

 

installed

 

using

 

the

 

provided

 

FKM

 

mounting

 

gasket.

  

Make

 

sure

 

that

 

the

 

fitting

 

and

 

transmitter

 

threads

 

are

 

not

 

damaged

 

or

 

worn.

  

Always

 

hand

tighten

 

the

 

transmitter

 

within

 

the

 

fitting.

  

Perform

 

an

 

installed

 

leak

 

test

 

under

 

normal

 

process

 

conditions

 

prior

 

to

 

system

 

start

 

up.

  

Note:

 

The

 

preferred

 

mounting

 

fitting

 

for

 

the

 

LVU2810

 

series

 

is

 

a

a.

 

For

 

LVU2810

 

Series

 ‐ 

mount

 

at

 

least

 

2”

 

from

 

the

4.

 

Do

 

not

 

mount

 

where

will

 

intrude

 

on

See

 

Specifications

 

on

5.

 

Do

 

not

 

mount

 

in

 

a

 

vacuum

 

6.

 

Avoid

 

mounting

 

in

 

the

 

center

 

of

 

a

 

dome

 

top

 

tank.

 

7.

 

In

 

cone

 

bottom

 

tank,

 

position

 

the

 

sensor

 

over

 

the

 

deepest

 

part

 

of

 

the

 

tank.

 

 

Do

 

not

 

install

 

at

 

angle

 

relative

 

to

 

the

 

liquid.

 

Do

 

not

 

install

 

within

 

3”

 

of

 

tank

 

sidewall.

 

Do

 

not

 

install

 

with

 

objects

 

in

 

the

 

beam.

 

Do

 

not

 

install

 

in

 

applications

 

with

 

vacuum.

 

 

Installation

 

in

 

existing

 

fittings

 

If

 

the

 

existing

 

fitting

 

is

 

larger

 

than

 

the

 

threads

 

of

 

the

 

LVU2800

 

Series,

 

select

 

a

 

reducer

 

bushing

 

such

 

as

 

a

 

2”

 

thread

 

x

 

1”

 

thread,

 

a

 

2”

 

slip

 

x

ultrasonic

 

transmitters

 

have

 

been

 

optimized

 

for

 

use

 

in

 

non

metallic

 

fittings.

   

1.

 

For

 

best

 

performance,

 

avoid

 

the

 

use

 

of

 

metallic

 

fittings.

   

a.

 

Use

 

a

 

plastic

 

2”

 

x

 

1”

 

reducer

 

bushing,

 

or

 

a

 

plastic

 

1”

 

flange

 

(See

on

 

next

 

page).

 

2.

 

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

 

coupling

 

is

 

tightly

 

wrapped

 

in

 

vinyl

 

tape

 

to

 

dampen

 

vibrations.
